I was working on validating some of my own project ideas.
While trying to find how to validate my idea, I realized the process itself could be turned into a tool.
A few late nights later, I had something that takes any startup idea, fetches discussions, summarizes sentiment, and gives a quick “validation score.”
It’s very rough, but it works, and it’s already making me rethink a few of my own ideas.
It's still a work in progress. I don't actually know what I'm doing, but I know it's worth it.
Honest feedback welcomed!

Hey HN! We've been working on Station, an open-source runtime for what we call "operational agents" - simpler AI agents focused on ops tasks rather than full application embedding.
The key insight was that agent management shouldn't be confined to your IDE. We built Station with an SSH-first approach using wish + bubbletea for a rich terminal experience that feels natural for ops workflows.
What makes Station different:
- MCP-native: Station itself is an MCP server supporting both STDIO and SSE, working seamlessly with Claude Desktop and other MCP clients
- Tool restrictions: Assign specific tools to agents to prevent model degradation from tool overload
- GitOps-friendly: MCP configs as template bundles with proper secrets management
- Single binary: Deploy anywhere with SQLite + optional Litestream replication
- Export flexibility: Generate dotprompt files to manually tweak agent behavior
- API access for programmatic control alongside the SSH interface
We're in early beta and would love feedback from the community. The vision is to make operational agents as easy to deploy and manage as any other ops tool.
GitHub: https://github.com/cloudshipai/station
Happy to answer questions about our architecture choices, MCP implementation, or anything else!

I'm building a workspace for doing focus work while also managing constant multi-tasking and context-switching that's required in a lot of roles. Currently this is done by using a notes system where we can split-screen AI chat, an object-based data table system for tracking entities, as well as viewing other documents.
We can define agents directly from documents by giving instructions in plain language and then defining the trigger conditions. This helps automate workflows directly in the place where we're reading and writing content.
I'm continuing to experiment with instructions and templates to figure out the best ways to automate tasks like content creation and responding to emails or leads.

Hi HN,
I’ve been working on Gore – a port of the classic Doom engine written in pure Go, based on a ccgo C-to-Go translation of Doom Generic. It loads original WAD files, uses a software renderer (no SDL or CGO, or Go dependencies outside the standard library). Still has a bit of unsafe code that I'm trying to get rid of, and various other caveats.
In the examples is a terminal-based renderer, which is entertaining, even though it's very hard to play with terminal-style input/output.
The goal is a clean, cross-platform, Go-native take on the Doom engine – fun to hack on, easy to read, and portable.
Code and instructions are at https://github.com/AndreRenaud/Gore
Would love feedback or thoughts.

Hi Hacker News,
I'm excited to share a small side project I've been working on: *www.chivalrytest.online*. This is a fun, quick online quiz designed to help people explore a concept that's often seen as archaic but holds timeless values: chivalry.
The idea behind this project isn't to be a historical authority. Instead, it's a lighthearted way to reflect on some core virtues that are still relevant today, such as:
* *Courage:* How do you react when faced with a difficult choice?
* *Honor:* What role do integrity and responsibility play in your decisions?
* *Humility:* Are you willing to admit your mistakes and learn from them?
The test asks a series of simple questions and provides a result that categorizes you as a specific type of knight, like a "Knight of Honor" or a "Knight of Wisdom." It's a quick and engaging way to spark some self-reflection.
I built this project using `html、JQuery、TailwindCSS` and it was a great learning experience. I'd love to get your feedback on the questions, the results, and the overall concept.
What do you think? Are these virtues still relevant in today's world?
Thanks for checking it out!

Hey HN!
I made a tiny tool called mirroranimage.com.
It does just one thing – flip or mirror any image – but it does it fast and entirely in your browser.
Why I built it
I often needed to mirror images for quick design checks, social posts, or just to see how something looks reversed. The problem? Most tools are slow, ad-filled, or upload your images somewhere. I wanted something instant, private, and pleasant to use.
What you can do:
 • Flip horizontally or vertically with one click
 • Drag & drop or paste directly from clipboard
 • No sign-up, no upload, no tracking – works 100% locally
 • Download instantly when you’re done
Why it’s nice:
 • It’s fast. Like, under 3 seconds fast.
 • No clutter – just you and your image
 • Works on desktop & mobile
Try it here → mirroranimage.com
I’d love feedback on what could make it even smoother.
Would batch mirroring or rotation be useful? Let me know!

30 days ago, I was just a backend dev writing CRUD APIs. Then AI came along — and suddenly, it felt like my skills might be obsolete.
The past two years have been a whirlwind. AI models now create images, videos, and even code faster than humans. I felt both amazed… and scared. If AI could do my job, what would be left for me?
Instead of waiting for the wave to wash over me, I decided to build something of my own. Video tools were too costly, so I started with images — the foundation of video — and began working on photor.ai, an AI-powered image generation and editing tool.
No design skills. No frontend experience. No budget.
1.V0 for the product page
2.Cursor for both frontend & backend code
3.GitHub for source control
4.Cloudflare Pages for hosting frontend
5.A tiny cloud server for the backend
It wasn’t smooth:
1.Broke deployments at 2 a.m. more than once
2.Rebuilt features from scratch when early versions failed
3.Hit API rate limits just hours before launch
There was a night I nearly quit. I told myself, “Maybe I’m not cut out for this. I’m just a CRUD dev.”
The next morning, I decided to keep going anyway. One bug at a time, one feature at a time, one tiny improvement at a time. Slowly, photor.ai came to life.
If there’s one thing I’ve learned, it’s this: you don’t need to be a “full-stack rockstar” to launch something in the AI era. Curiosity and persistence matter more than credentials.
If you’ve been hesitating, start now. Even if it’s messy, even if it’s small — the best way to understand this new era is to create in it.

In the era of big models, the barrier to entry for mind mapping has become lower. While many software programs offer built-in functionality, their features are limited.
For example:
1. Generated mind maps cannot be edited.
2. Mind maps cannot be exported to other formats.
My idea was to create a lightweight tool that would meet the needs of novice users and require only a single operation. Therefore, I've broken down various functions into separate software, including PDF, image, URL, and text generation. Other features will be added later.

Introducing Coherence OS / Coherence UI
This tool resolves in part several frustrations I have with attempting to accelerate actual production ready outputs from my collaborations with AI.
It solves the fact that the best AIs fail to allow infinite memory, in 2s, through copy and paste into the system.
It solves the issue of privacy with sensitive IP that I don't want leaked to big brother, while retaining AI accelerants.
It creates a personal knowledge base that you control on your computer locally, instantly searchable.
It exports sections of that to external AI instantly as you deem fit to create a 2nd brain for your collaborations with AI thats infinite in scope.
And its all built within a project management framework, GTD, one of the worlds most established. So it manages to do lists, habit lists and you don't have to write down what you got done to instantly see and celebrate it, its built for you.
Plus it provides a system for AI to do your work for you in a fashion much more efficient that chatGPT chat or claude chat Alone.
The Video attached shows a peek into my accelerated learning stack, AMA.  Its one part of how I use Coherence and GPT and Text Expander to accelerate learning anything.
Right now Im building ( with no effort given the coherence tools solving of critical gaps ) a tool for mock interviews and interview prep for the high paying machine learning roles in silicon valley...
This is a peek into that.
Love your feedback.
Target is prepping for open source release, not public yet but your feedback or collaboration offers will accelerate that, and if you want early access we will shoot an invite to folks registered at ixcoach.com so grab a free account there to get on the mailing list if you want a heads up first.
Tell me what you think.  Its far from perfect but Im addicted to it, it went down for a day and drove me nuts ( while I was upgrading and adding auth ), I was pulling my hair out, its been so essential to me.
Target impact
Subjective:
Allow you to make sense of your world, drop all of the chaos you find riveting into one place, then act on it in an organized fashion.
Intersubjective:
Break from the "we own your data" drama of the western world, empower those who value privacy on principle
Give private actors who want full capability full control and leverage with ai
Objective:
Provide tangible tools that impact human flourishing
Systemic:
Power open source past the boundaries of capitalism, optimize for impact at scale and prove this can self sustain:  alignment + impact + scalability + healthy unit economics

Hi, I implemented a real-time physics simulation optimized with multithreading. The simulation runs on your browser, so check it out if you're interested!
You can drag the soft bodies, and change the simulation boundary size by resizing the window.
Demo: https://floaty-fluid.netlify.app/
Repo: https://github.com/matsuoka-601/Floaty
I'll briefly explain how it works under the hood.
For simulating fluid and soft bodies, a method called Position Based Dynamics (PBD) is used. This method is often chosen when real-time performance is required. Fluid and soft bodies interact with each other, and buoyancy is simulated based on a paper "Unified Particle Physics for Real-Time Applications".
The most time consuming part of the solver is optimized with wasm-bindgen-rayon. Since PBD is relatively easy to parallelize, multithreading greatly improves the performance of the solver. Thanks to this, the simulation runs smoothly on relatively weak devices I guess.

Hey everyone! I recently built ThumbFlow AI, an AI-powered tool that creates viral YouTube thumbnails in seconds. I'd like to share it with the HN community.
*How it started:* As a solo maker, I kept seeing creators struggling with thumbnail creation - either spending hours learning design tools or paying $50+ for each thumbnail from freelancers. Most existing AI tools produce mediocre results that don't actually drive clicks. I thought there had to be a better way to solve this.
*What makes ThumbFlow different?*
*4-in-1 AI toolkit in one chat interface:*
- Text-to-Image: Just describe your scene, get a complete thumbnail
- Background Transform: Upload any photo, AI changes the background while keeping the subject
- Face Swap: Natural face replacement for brand consistency
- Smart Edit: Use plain English like "make the text bolder" or "darker sky"
*Built for actual results:* Early users report 3x higher click-through rates compared to their previous thumbnails. One creator told me a thumbnail made in 30 seconds helped their video go viral.
*Transparent pricing:* Every operation costs exactly 5 credits. No hidden fees, no complex tiers based on features. New users get 20 free credits to try everything.
*Real usage scenarios:*
*YouTube Creators:* Stop spending hours in Photoshop or paying designers. Describe your hook → get a click-worthy thumbnail in seconds.
*Small Businesses:* Need product promo images? Upload your product photo, tell the AI to put it in any scene you want.
*Social Media Managers:* Maintain consistent branding across channels with face swap, then customize backgrounds for different platforms.
*Content Agencies:* Batch-create thumbnails for multiple clients without hiring a design team.
*How to use:* Super simple, just like chatting:
1. Sign up at https://thumbflow.io (20 free credits, no card needed)
2. Go to /create and either describe a scene or upload a photo
3. AI generates your thumbnail in ~15 seconds
4. Download or use smart edit to fine-tune
*Technical details for the curious:*
- Built with Next.js 14 + Supabase + TypeScript
- Uses state-of-the-art AI models optimized specifically for thumbnail generation
- Real-time chat interface with session management
- Integrated payment processing and credit system
- All images stored securely with user ownership
*Try it here:* https://thumbflow.io/create
*Current status:* Fully launched with paying customers! The core functionality is solid, and I'm now working on features like template libraries and batch processing based on user feedback.
*Special offer for HN:* Use code RMZYR9OMPZ for 40% off your first 3 months if you decide to subscribe.
I'd love to hear your thoughts! What other AI-powered creative tools would be useful for content creators? Any technical questions about the implementation?

Hey everyone,
I want to show you my iOS app.
For the past 8 months I worked on this revamp and the app was approved on the App Store two days ago on the first go.
How did I come up with the idea?
Last year while I was looking for a new app to build I found lots of Reddit posts where people were asking about "How to practice flirting" or "How to flirt". Most of the posts had a ton of engagement and I thought that it might be a good opportunity to build an app which helps people with this problem.
The first version of the app was not great, but I got 4 customers and made $94. Two paid monthly and 2 paid for the yearly subscription.
What problem does the app solve?
Online dating apps are "broken". You either get no matches or if you somehow match you are ghosted or you have no clue how to avoid an awkward conversation.
We have to learn how to engage better in offline and online conversations.
How does the app solve the problem?
* There are over 120 structured video & text lessons, each with multiple questions. On each response you receive feedback and if you still have things to clarify you can ask an Ai tutor questions about the lesson.
* Real-world scenarios with voice practice. Multiple scenarios like coffee shop meeting or at the dog park etc. You have a goal and some tasks. Don't worry If you get stuck during the conversation, you can ask for hints. During the conversation an Ai analyzes your emotions through your language and at the end of the conversation you will receive a beautiful report which you can use to improve, see strengths or fix your weaknesses.
* 3 Daily challenges with different difficulty levels.
* Stats screen where you can see progress
I have a ton of ideas on stuff to do in the app, but I ll implement them slowly. Now I'm trying to get feedback from users.
The app is behind a paywall after sign in, because it might have Ai APIs cost. If you feel the subscription is too expensive or cannot afford DM and I'll make your account paid in exchange for feedback ( Make sure you don't hide email when you sign in so I can find you in the db )
Looking forward to your feedback.
Thank you

Hi HN,
I built a library to simplify Digital ID verification because existing protocols are overcomplicated and locked behind expensive ISO specs.
I think the recent Tea app fiasco is a good enough example for why uploading your full ID everywhere is a terrible idea. That's partly why I'm a fan of mobile ids with selective disclosure (e.g. proving you're over 21 without revealing your actual birthdate).
Unfortunately, besides the existing protocols being inaccessible and complex, there are already 4 different credential formats that you might want to support, and there's no automated process for verifying that the ID actually came from an issuer you trust. So I built this library to abstract out the protocols, various formats, and automatically verify the ID against trusted issuer lists like the AAMVA DTS or my wrapper for Apple's recommended IACA certs. Issuer info is indexed on an open source trusted-issuer-registry that I also built that automatically fetches the latest information from supported trust lists.
Hope someone finds it useful, and would love any feedback folks have!

The principle is to use the hash of a Git empty commit as the unique identifier for a short link, storing the original long link in the commit message. When the short link is accessed, the system retrieves the long link by requesting the corresponding .patch file from GitHub and performs a redirect. Combined with the analytics dashboard of a WAF (Web Application Firewall), this creates a link shortening service with access statistics.

My co-founder and I work in B2B sales. We’ve seen how genuine prospect research and personalized outreach can win deals — but also how exhausting it is to manually research and track every prospect.
We tried CRMs and popular sales intelligence tools, but they felt like static directories — good for contacts, not for real insights or engagement. GPTs were great at generating content, but to get a usable Customer 360° strategy, we had to constantly engineer prompts and feed it fresh data about both the customer and us.
So we built intellisell.ai — an AI-first sales research assistant that:
a) Aggregates information from multiple public sources, and
b) Uses AI to deduce and distill it into insights and strategies that align with your solution.
The User Experience:
- You complete your profile (your solution, ICP, UVP) once.
- You then provide the company URLs you want to track
- We aggregate company information from multiple sources across web, news, social media, etc
- We then feed this context and structured prompts to build a comprehensive account profile.
- You can then
 Ask any questions - e.g "What are the top 3 priorities for their CTO based on recent interviews?" or "Draft me an email referencing their latest product launch."
 Auto-Generate a comprehensive account plan and Engagement Strategy - matching your solution and ICP.
 Track updates & buying signals - See a weekly summarised view of the latest updates with insight and buying signals, sentiment, and tags.
We're trying to build something more dynamic than a CRM and more strategic than a simple data firehose. Instead of just giving you data, it helps connect the dots.
Is this a problem you or your sales teams have faced? We would love to hear your feedback.

I got tired of SSH-ing into each of my servers to run htop and check disk usage, so I built SSH Monitor – a terminal-based dashboard that monitors all your remote hosts in real-time.
Key features:
• Automatically discovers hosts from your ~/.ssh/config
• Real-time CPU, memory, disk, and GPU monitoring
• Timeline charts showing historical usage
• One-line installer: curl -sSL https://raw.githubusercontent.com/tsugumi-sys/ssh-monitor/ma... | bash
• SQLite storage for historical data
• Cross-platform (Linux, macOS Intel/ARM)
GitHub: https://github.com/tsugumi-sys/ssh-monitor
Would love feedback on the UX and feature suggestions!

Try it: We mapped 2,970 Y Combinator companies in 3D by product similarity - 57% of YC's entire portfolio since 2005. Jump right in and explore: pan/zoom around, click for detailed profiles, explore clusters.
No signup required, works best on desktop.
Why
Sometimes it's hard to grasp the bigger picture and see the forest for the trees. This map gives an overall representation of the whole space - companies, clusters, and outliers (companies that don't have obvious similar counterparts). For example, there are three companies supporting innovation labs. Also it's fun to see how LegalTech is very compact but very far away cluster.
What stood out
A surprisingly large Government & Public Sector Solutions cluster and Accounting for SMBs.
LegalTech forms a compact but isolated cluster.
And three lone outliers — all research lab equipment companies.
How it works
Input: company URL → Our own crawler extracts product signals from public pages.
Representation: ML embeddings (multidimensional similarity).
Projection: UMAP algorithm reduces to 3D coordinates.
Clustering: hybrid algorithm groups similar companies; clusters auto-labeled by AI. Anthropic has similar approach in their Clio paper, if someone is interested.
UI: three.js scene + d3 interactions (search/filter/hover).
Visualization inspired by Music Galaxy (https://galaxy.spotifytrack.net/)
Scope & coverage
Dataset: 2,970 companies from YC's 5,200+ portfolio (Summer 2005 to August 2025).
Coverage includes active companies plus many acquired/defunct ones we could access.
We respected robots.txt; some sites missing or had limited crawlable content.
UMAP is non-deterministic; we use consistent seeds but local neighborhoods can shift.
Similarity ≠ endorsement; not affiliated with YC!
Looking for feedback
This sits on top of our B2B company mapping engine and we are launching more products.
Would letting you drop in any company URL to see where it lands be useful? API?
Roadmap
Projecting any company in this space for comparison;
Regular refresh as companies pivot and grow;
API to get consteallation for your own project.
Learnings
Visualization started as a small project with 5 moving points in 3D space and escalated to a full solution based on three.js and d3. This wouldn't be possible without AI assistance powering data collection, embeddings, and clustering.
Happy to dig into the technical details if folks are curious.

I've been using AI coding assistants like Copilot and Claude a lot, but I constantly hit the limits of their context windows, forcing me to re-explain my code over and over. I also work on projects with sensitive IP, so sending code to a third-party service is a non-starter.
To solve this, I built AntiGoldfishMode: a CLI tool that gives your AI assistant a persistent, local-only memory of your codebase. There are enough cloud-based tools that solves some of the issues relating to AI persistent memory, but not a lot that combines all the features I have placed in AGM.
- Verifiable Zero-Egress - How to verify: Run agm prove-offline
- Supply Chain Integrity for Shared Context: The .agmctx Bundle, Checksums First, Cryptographic Signature: An Ed25519 key pair (generated and stored locally in keys) is used to sign the SHA-256 hash of the concatenated checksums. This signature is stored in signature.bin.
- Policy-Driven Operation
- Transparent Auditing via Receipts and Journal. You should never have to wonder what the tool or your AI coding agent did. It is like a "Glass Box" where you see and verify every move your AI coding agent makes, every edit is recorded.
Receipts: Every significant command (export, import, index-code, etc.) generates a JSON receipt in receipts. This receipt contains a cryptographic hash of the inputs and outputs, timing data, and a summary of the operation.
Journal: A journal.jsonl file provides a chronological, append-only log of every command executed and its corresponding receipt ID. This gives you a complete, verifiable audit trail of all actions performed by the tool.
This combination of features is designed to provide a tool that is not only powerful but also transparent, verifiable, and secure enough for the most sensitive development environments.
It's built with a few core principles in mind:
Local-First & Air-Gapped: All data is stored on your machine. The tool is designed to work entirely offline, and you can prove it with the agm prove-offline command.
Traceable & Verifiable: Every action is logged, and all context exports can be cryptographically signed and checksummed, so you can verify the integrity of your data.
No Telemetry: The tool doesn't collect any usage data.
The core features are MIT-licensed and free to use. There are also some honor-system "Pro" features for advanced code analysis and stricter security controls, which are aimed at professional developers and teams.

Hey,
I'm really excited to release Claude Control today.
You can check it out here - https://claudecontrol.com
It's an app which connects claude code to your Slack & Discord and lets you open PRs and iterate on them without leaving the chat app.
More importantly, it lets you share this with your whole team or community.
Quite frequently, non-technical people on the team or support engineers would like to understand how something in the product works, so this lets them get their answer without setting up anything, just by chatting with Claude Code.
I think it also unlocks a lot of other capabilities, a few that come to mind:
 - run it in your docs repo & let it answer questions for your slack/discord community
 - connect notion via mcp and let it work as an always available knowledge base in your slack
There's probably a lot more interesting use-cases.
It's currently free in open beta and I can't wait for you to try it out. I'm actively iterating on it and looking for some engaged early users to help me shape the app direction.
Hope you like it & find it useful!

Hi HN community,
I built this because I was tired of juggling 3–4 different tools just to work on a single project.
When I’m doing research, analysis, plain old reading or knowledge work I usually have:
A note-taking app open
A PDF viewer in another window
ChatGPT in a separate tab
Switching between them constantly killed my focus and made it harder to connect information.
So I decided to merge everything into one workspace:
Rich text editor for notes
PDF viewer for reading & annotating documents
AI chat assistant for instant summaries, Q&A, and analysis
You can open multiple files at once and resize panels however you want. It’s already been helpful for students, lawyers, consultants and pretty much anyone with multiple sources of information at once or just likes to have everything in one window.
I’d love for you to try it and tell me what you think, what works, what doesn’t, and what’s missing.

Hi HN, my name is Emre. I am one of the co-founders of Fume - a tool to generate Playwright test suites from product walkthrough videos.
HOW DOES IT WORK
1. Upload a Loom or equivalent video where you describe what you want to be tested in your app
2. Gemini extracts test scenarios
3. We spawn multiple computer-use agents in parallel to explore your app and write Playwright code.
WHAT’S DIFFERENT
Your voice and a screen recording is the most natural way of describing what you want to be tested in an app. Compared to other test builders (AI powered or not) you do not have to spell out steps, think about test design or dynamic data within the app.
HOW YOU CAN TRY IT
We have a no-sign-up demo at https://app.fumedev.com/demo
Would love to hear what you think of this UX for creating Playwright tests. Especially if you wrote E2E tests before or used any of the test builders.

Hi HN,
I'm Adriano, one of the makers of Vaultrice. I'm excited (and a little nervous!) to share what we've been building.
For years, we found ourselves in a frustrating loop: whenever we needed a simple real-time feature—like a "who's online" list, a collaborative app, or just sharing state between a marketing site and our main app — we'd end up spending days setting up the same stack or discarded to do it. Setting it up, it always involved wiring together a database, a WebSocket server, an API, and managing the connection state. It felt like massive overkill for what we were trying to achieve.
We wanted a tool that felt as simple to use as the browser's `localStorage` API but worked across domains and devices, with real-time sync and security built-in.
So, we built Vaultrice.
It’s a key-value data store built on top of Cloudflare's Durable Objects, which gives you a strongly consistent backend for each data object. You interact with it through our TS/JS SDK, which comes in two flavors:
1.  `NonLocalStorage`: A low-level client with a `localStorage`-like API (`setItem`, `getItem`, etc.) plus real-time events and presence (`.on()`, `.join()`).
2.  `SyncObject`: A higher-level, reactive JavaScript Proxy. You just change a property on an object (`doc.title = 'New Title'`), and it automatically syncs to all other connected clients.
The goal is to let you build the real-time features you want in minutes, not days. We've also put a lot of thought into a layered security model, allowing you to go from simple API key restrictions all the way to server-signed object IDs and client-side E2EE.
We’ve just launched and would be grateful for any feedback from the HN community. What do you think of the API design? Are there use cases we haven't considered? Any thoughts on the security model?
We'll be here (or via email (support@vaultrice.com)) to answer any questions. Thanks for checking it out!

Hey HN, this is Igor, one of the engineers behind Inworld Runtime, which we're releasing today in public preview.
We built it to solve the common problem we and our customers had: engineers spend more time on AI ops and plumbing than on actual feature development. This was often due to the challenge of using Python for I/O-bound, high-concurrency workloads and complexity maintaining pipelines with streams that use always-changing ML models.
Our solution is a high-performance runtime written in C++ with the core idea of defining AI logic as  graphs. For instance, a basic voice-to-voice agent consists of STT → LLM → TTS nodes, while the connecting edges stream data and enforce conditions. This graph engine is portable (Linux, Windows, macOS) and can run on-device.
We built a few key features on top of this C++ core:
- Extensions. Runtime architecture decouples graph definition from implementation. If a pre-built component doesn't exist, you can register your own custom node/code and reuse it in any graph without writing any glue code.
- Routers. You can dynamically select models/settings on the per-node basis depending on the traffic as well as configure policies for fallbacks and retries to get the app ready for production.
- The Portal. A web-based control plane UI to deploy graphs, push config changes instantly, run A/B tests on live traffic, and monitor your app with logs, traces, and metrics.
- Unified API. Use our optimized models or route to providers like OpenAI, Anthropic, and Google through a single, consistent interface and one API key.
We have a Node.js SDK out now, with Python, Unity, Unreal, and native C++ coming soon. We plan to open-source the SDKs, starting with Node.js.
The docs are here: https://docs.inworld.ai/docs/runtime/overview
We're eager for feedback from fellow engineers and builders. What do you think?

About nine months ago I posted about a language I had begun experimenting with, called XferLang. I got several helpful comments, and since then I've completely revamped the design and built a complete language spec and library around it. I've even integrated it into some apps I use daily. The language, intended to be an alternative to JSON and YAML, is a strongly typed, human‑readable/writable, structured text language. Where it differs from JSON is support for comments, strict typing of data, support for processing instructions (which are extensible), nascent scripting features, and embedding of text without the need for character escaping.
Right now it is implemented in a .NET 8.0 library, but I want to port it to other languages as well.
I'm looking for critiques on the language's ergonomics, opinions on its real-world applicability, and any reasons you would or wouldn't adopt something like this over JSON/YAML/TOML. Thanks for your feedback!

I hacked this together last week; it’s still very experimental. The goal is simple: help founders prioritize outreach by surfacing investors who’ve recently raised funds (i.e., have capital to deploy). Right now we diff recent EDGAR/Form D filings and public announcements, normalize to a Postgres schema (fund → check size, stage, sector, geo, contacts), and do light entity resolution for aliases/shells. Expect gaps and false positives while we iterate.
Grants: today we’re only pulling federal sources (SBIR/STTR, Grants.gov). The roadmap is to add state, county, and municipal portals, plus agency- and foundation-specific programs—basically anything a startup can actually apply for.
Also included: accelerators/venture builders (terms, equity, timelines) and a “founder freebies” section (~$4.5M in credits/tools many teams miss).
We've kept it simple: no login wall, no upsell, no paid introductions.
This is a working prototype we plan to keep improving.

I’ve been tinkering with AI search optimization and noticed a gap: most brands have no idea whether they show up when someone asks ChatGPT (or other LLMs) for relevant recommendations.
If you’re invisible there, you’re invisible to a growing slice of your potential audience.
Enterprise tools (Profound, Semrush AIO, etc.) track this for big companies on pricey subscriptions, but I wanted something a small team or indie maker could run in seconds, with no recurring cost.
GetGPTScore works like this:
- Enter your brand website url
- We run targeted prompts against ChatGPT (Search mode)
- See a GPTScore (0–100) + top fixes to improve it
You get a the full report for $4.99 flat—no upsells, no monthly plan.
Roadmap: Add Perplexity, Google AI Overviews, Claude, Gemini.
Built with Python + OpenAI APIs under the hood. Nothing fancy, but it solved my own frustration trying to get a side project cited in AI answers.
Would love feedback from HN:
- Is a single “AI visibility score” useful?
- Should I expand to more engines first or go deeper into ChatGPT?

Claude Code and Cursor can run (semi-)productively for increasingly long times without supervision (at least on side projects I don't care too much about). I built an MCP server that lets agents page your phone (free iOS and Android apps) with an alert when they're done so I could walk away from my desk.
30 second demo videos:
Cursor: https://youtu.be/Zod_1ChbqGc
Claude Code: https://youtu.be/e1HSazkcKz0
No need to host an MCP server instance: just drop a URL+token into your `mcp.json` or `claude mcp add` and you can get your first alert in under a minute. I recommend you start with a simple prompt such as: "Calculate the square root of 64 and page me with the answer" to test it out quickly before you try long-running prompts.

Hi, I’m Rok!
I recently started my solopreneur journey and quickly realized how much Domain Rating (DR) impacts traffic and growth, so I looked into existing directory listing services.
I was speechless when I found out that you can’t get your domain submitted to 100 directories for less than $200. In some cases, it was even $500! What’s worse?
They claim they’re using AI to automate the process. Either they’re lying because it’s cool to put "AI" in their marketing, or scamming you with insanely high prices.
That’s why I built AutoLaunched for myself and proved that you can automate directory submissions and make the process 10x cheaper and 1,000x faster.
I’m opening pre-orders to see if other founders want this too. If enough of you join, I’ll launch AutoLaunched. If not, you’ll get a full refund!
As a pre-order supporter, you’ll get 20% off FOR LIFE, as long as AutoLaunched exists. This exclusive lifetime discount will never be offered again after launch.

In everyday development, we sometimes need to develop in a highly secure environment. This leads to the existence of internal and external networks.
The internal network cannot use npm for dependency installation. Imagine if we added a new project on the external network each time and needed to synchronize it with the internal network for development—would we have to package the entire node_modules directory and transfer it to the internal network? This is clearly impractical.
The best approach is to set up Verdaccio on the internal network. Each time, we only need to synchronize our source code to the internal network. Therefore, managing dependencies between the internal and external networks becomes critical.
Common Issues with Verdaccio Usage
1. Manual publishing is cumbersome: Each package must be manually published to verdaccio using npm publish. When there are many packages, the workload is enormous, and the publication time is unpredictable.
2. verdaccio may not display packages that already exist, resulting in a poor user experience
3. Complex dependency relationships: Packages may have complex dependency relationships, and manual publishing is prone to omitting dependent packages
4. Repetitive work: Every project update requires manually republishing all related packages
5. Low efficiency: The entire process is time-consuming and labor-intensive, impacting development efficiency
Problems Solved by sptv-cli
1. Automated Synchronization: One-click automatic synchronization of external packages to internal Verdaccio, eliminating manual publishing
2. Intelligent Dependency Scanning: Automatically scans and identifies package dependencies, ensuring all dependent packages are synchronized
3. Batch Processing: Supports batch processing of multiple packages, greatly improving synchronization efficiency
4. Version Consistency: Ensures package versions in internal Verdaccio are completely consistent with external networks
5. Progress Visualization: Real-time display of synchronization progress, keeping users informed of operation status
6. Flexible Configuration: Supports multiple configuration options to adapt to different usage scenarios
SPTV-CLI allows you to focus solely on managing your packages.

Hi, I’m Rok!
I’ve always wanted to build something of my own. But for years, I had no ideas. I was that guy, endlessly scrolling through Reddit threads about “how to get startup ideas,” hoping for a lightbulb moment that never came.
Recently, I stumbled on a Starter Story YouTube video. Steph France was talking about something he called the “Gold Mining Framework.” Guess what? Reddit itself is one of the best places to find startup ideas.
There are over 1 billion active Reddit users and 150,000 Subreddits. People share what they need and what they don’t need every day. If you listen, you can find problems worth solving. And when you solve real problems, you have a much better chance of success.
But there’s a catch! Steph’s method works, but it’s painfully manual. That’s why I built r/KaChing for myself and proved that you can automate startup idea generation.
Now, I’m opening pre-orders to see if other aspiring founders would find it as game-changing as I do. If enough of you join, I’ll launch r/KaChing. If not, everyone gets a full refund!

# gitego: Automatic Git Identity Switcher
I was juggling work and personal GitHub accounts with separate PATs for a long time and constantly forgetting to switch between them. Needed a way to commit to personal and work projects without the mental overhead of managing two Git identities.
My issue:
```<p>cd ~/work/important-project<p>git push<p>#  Authentication failed - using personal PAT for work repo<p>```
Then the dance:
```<p>git config user.email "work@company.com"<p># Update Git credential helper or remember which PAT to use<p># Rinse and repeat every time I switch contexts<p>```
My solution (I'm sure others exist?)
```<p># One-time setup<p>gitego add work --name "John Doe" --email "john@company.com" --pat "ghp_work_token"<p>gitego add personal --name "John" --email "john.personal@gmail.com" --pat "ghp_personal_token"<p>gitego auto ~/work/ work<p>gitego auto ~/personal/ personal<p># Now it just works
cd ~/work/any-project<p>git commit -m "fix bug" && git push  #  Uses work identity + PAT automatically<p>cd ~/personal/side-project<p>git commit -m "new feature" && git push  #  Uses personal identity PAT automatically<p>```
How It Works
- Uses Git's native `includeIf` for identity switching
- Acts as a Git credential helper for automatic PAT selection
- Stores PATs securely in your OS keychain
- Single Go binary, works on macOS/Windows/Linux
No more context switching overhead. Just cd and commit.

Install: go install github.com/bgreenwell/gitego@latest
Feedback welcome!
Keep in mind, I built this as a personal tool, making it public in case others have the similar problems and can benefit from the solution!

I built a multi-agent AI orchestration system and then had AI generate the ebook about the build from the project’s real artifacts: test outputs, Git commits, and CLI-generated docs.
It’s not a cleaned-up case study; it mirrors the actual workflow (failures, refactors, trade-offs).
What it is
 • AI Team Orchestrator: a free beta “captain’s log” of the build
 • Focus: architecture, orchestration patterns, memory, quality gates, evals/guardrails, and ops
Why it’s different
 • Content was compiled automatically by AI from dev exhaust (tests/commits/docs), then lightly edited
 • Emphasis on applied practices over prompt tinkering
Who it’s for
 • Builders shipping multi-agent systems
 • Founders/PMs evaluating AI ops beyond toy demos
 • Engineers interested in the glue: orchestration > single-agent prompts
Looking for feedback
 1. Where should I go deeper: orchestration vs. monitoring/telemetry vs. cost control?
 2. Would a starter repo + checklists be more useful than more chapters?
 3. What quality-gate thresholds do you use to keep progress moving without rubber-stamping junk?
Notes
 • Free, no email gate
 • Early beta; happy to share prompts/pipeline if useful

Hi HN,
I’ve been working on Magicnode — a visual platform to build AI-powered apps without writing code, and then share, embed, or monetize them. Think “Canva for AI apps”.
The idea came from repeatedly seeing friends and colleagues who had ideas for small AI tools (e.g., lead generation bots, TikTok content generators, onboarding assistants) but didn’t have the coding skills or time to build them. Existing no-code tools often require a steep learning curve or lots of manual integrations — we wanted something you could use in minutes, not hours.
With Magicnode you can:
Create an app by dragging blocks (prompts, APIs, UI components) on a canvas.
Share it instantly with a link, or embed it on a website.
Let others “remix” your app to make their own version.
Optionally publish to our public App Store for discoverability.
A few example apps made in Magicnode:
Podcast Summarizer → paste a link, get a 5-bullet summary.
Viral Caption Generator for TikTok videos.
Custom PDF Chatbot for onboarding docs.
We’d love feedback from the HN community, especially on:
Use cases you’d like to see pre-built.
Features we could add to make this useful for technical users.
Thoughts on our “remix” model for app virality.
You can try it here: https://magicnode.ai (no signup needed to test a demo).
Happy to answer all questions, and if anyone wants to build something together on Magicnode, I’d be excited to collaborate.

I’ve lost count of how many times I’ve rewritten CSV importers and webhook parsers over the years.
I built IngressKit to handle that once and for all. It’s an API plugin that:
Cleans & maps CSV/Excel uploads to your schema.
Harmonizes webhook payloads (Stripe, GitHub, Slack, etc.) into one predictable format.
Normalizes JSON output from LLMs or third-party APIs to a strict schema.
Key details:
Deterministic — not probabilistic — normalization.
Per-tenant memory so it gets better over time.
Audit trail for every change.
Quick example:
curl -X POST "https://api.ingresskit.com/v1/json/normalize?schema=contacts" \
-H "Content-Type: application/json" \
-d '{"Email":"USER@EXAMPLE.COM","Phone":"(555) 123-4567","Name":" Doe, Jane "}'
→ Returns perfectly normalized JSON with consistent keys, formatting, and validation.

Would love feedback from the HN community — particularly on:

What works today
Scene based authoring with simple branching and light state
Choice timers in the 1.0 to 2.0 second range with auto advance
Preloading to cut stalls on mobile
Optional ecommerce embed so a CTA can be shoppable
Defaults I use
First choice at 5 to 7 seconds
Total length 20 to 60 seconds
One or two variables to gate a payoff
Prebuffer the next two scenes

I created a Docker container that packages Claude Code in a completely isolated environment. This solves the problem of wanting to try AI development tools without installing them directly on your system.
Credentials are persisted via bind mounts, with clean workspace access and easy removal when done experimenting. Perfect for developers who are curious about AI coding assistance but cautious about system-wide installations.
The container maintains all the functionality of Claude Code while keeping your host system pristine. Just docker run, authenticate once, and start coding with AI help. Remove the container later and there are no traces left behind.
The README on GitHub has examples for easy integration into existing projects. I welcome suggestions and feedback!

What it is
A practical pipeline to go from video → transcripts → bilingual subtitles (A/B at once) or voice dub (choose female or male). It targets lectures, tutorials, tech talks etc
Current constraints (honest version)
No speaker diarization yet → one TTS voice for the entire video
Voice choice: female / male
Bilingual subtitles (e.g., EN+JP, EN+ZH, EN+KR) with length-aware line breaking
You can add customized terms and translations in front of the listening model and the translation model to get the best accuracy
Long videos: we re-anchor timestamps periodically to fight drift
Pipeline (condensed)
ASR with word-level timestamps
Segment cleanup + merge tiny fragments
MT twice → produce A/B subtitle tracks; constrain length to reduce overflow; have multiple language model to supervise/double check the translation quality
TTS → single voice (female/male) for the full track
Mixback → keep ambience, duck original, SRT (mono or dual-lang) + dubbed MP4
Why post this now
It’s not “magic studio” quality, but it’s dependable for many real-world cases: course videos, onboarding, webinars. We found being explicit about limits (no diarization) actually speeds teams up.
What we’d love feedback on
The current User experience
Acceptable subtitle overflow rate on 30–60 min content
TTS pacing rules that feel most natural for multilingual reading speed
(If there’s interest, we’ll extract a minimal CLI with the exact steps and corner cases called out.)

We built this over the past week - Reverie, a GPT driven roleplay that blends interactive storytelling with cinematic video generation.
You type your actions, the plot advances and Wan 2.2 generates short “scenes” for interim hook moments — so you don’t just read the scene, you see it.
What it does
 • Lets you roleplay with fixed AI characters in real time.
 • Tracks character positions, obstacles, and state so scenes stay consistent.
 • Generates cinematic, frame-consistent video clips from the latest story beat.
 • Uses obstacle logic to maintain continuity (if a troll is on fire in scene 1, it stays on fire until the plot changes).
Tech
 • Story + dialogue: GPT with a structured RP prompt system.
 • Video: Wan 2.2 for text-to-video generation.
 • State tracking: Previous messages.
Why We made it
Most LLM roleplay feels like a chat log. We wanted something that feels more like a movie — immersive, reactive, and visual. We are aiming for Interactive Movie than Generative Games.
Observation
 • Wan 2.2 consistently adheres to prompts better than Wan 2.1.
 •       GPT-4.1 is excellent at text RP, maintaining better prompt adherence than 4o.
Current limitations
 • Video generation takes 30s per clip at 480p so can use once per turn rather than completely displace text.
 • Wan 2.2 still struggles with verbose aciton shots since it can generate only 5s video.
 • Character consitency forced us to only focus on main obstacles in a scene like monsters.
Future direction
 • Implement streaming video gen with Wan 2.2 following self-forcing, causvid papers
 • Character consistent workflows with comfyUI
 • Elaborate RP to track health, location map and more characters
 • More engaging Screenplay and Story lines
Demo - https://shorturl.at/L7zpR — Just pick a character and start.
Try it out here - https://www.reveriedr.com
Would love feedback on:
 • How to make the video feel even more like a live film set.
 • Ideas for better state tracking across long sessions.
 • Any moments where the immersion breaks for you.

I tried using the AudioContext API to make the most primitive browser-based multi-voice chiptune tracker conceivable. No frameworks or external dependencies were used, and the page source ought to be very readable.
Songs are written in plain, 7-bit safe text. Every line makes a voice/channel.
The examples given on the page should hopefully illustrate every feature, but as a quick overview: Sounds are specified using Anglo-style note names, with flat (black) keys being the lowercase version of the white key above so as to maintain one character per note. Hence, a full chromatic scale is AbBCdDeEFgGa. Every note name is interpreted as the closest instance of that note to the preceding one. +- skips up or down an octave, ~ holds the previous note for a beat, . skips a beat, 01234 chooses one of 5 preset timbres, <> makes beats slower or faster (for all channels), () makes the current channel louder or quieter. All other characters are ignored.
If you come up with a good tune, please share it in the comments!

We just launched SwarmZero, a platform for building, orchestrating, and monetizing AI agents without needing to code.
Most no-code AI tools are still designed for developers. SwarmZero is built to be truly accessible, so anyone with domain expertise can create an AI agent in minutes; no technical skills required!
The platform includes:
* No-code AI agent builder that connects to tools like Slack, Salesforce, Gmail, and more
* Orchestration for multi-agent swarms that can work together on complex workflows
* A marketplace (currently early-stage) where you can publish and share your agents, and in the future, monetize them
* Ability to “hire” agents built by experts from anywhere in the world
The goal is to make it possible for anyone to go from an idea to a working commercializable AI agent that solves real problems, without having to start a company, build a brand, or do distribution from scratch.
Would love feedback from the HN community on what we’ve built so far and what features you’d like to see next.

I was building an AI sales agent and hit same wall again. I was building a custom rule engine to determine how the agent should act.
Started thinking about how you could give AI agents safe and bounded permissions to act independently across multiple services without littering your code base with a bunch of conditionals?
I've repeatedly built these constraint systems before, it's always rate limiters in the email tool, domain filters in the CRM, spend limits in the payment processor. Every time, I (and others) end up solving the same auth/constraint problems independently.
So I built what I'm calling AAIP: The AI Agent Identity Protocol. It's a stateless standard for creating cryptographically signed delegations for AI agents.
With this, you can just create a "delegation". This serves as a signed permission slip, that specifies exactly what an agent can do, for how long, and with what constraints
{
  "aaip_version": "1.0",
  "delegation": {
    "id": "del_01H8QK9J2M3N4P5Q6R7S8T9V0W",
    "issuer": {
      "id": "user@example.com",
      "type": "oauth",
      "public_key": "public-key"
    },
    "subject": {
      "id": "outbound_agent_v1",
      "type": "custom"
    },
    "scope": ["email:send", "crm:read", "prospects:research"],
    "constraints": {
      "max_amount": {"value": 50, "unit": "email"},
      "blocked_domains": ["competitor1.com", "competitor2.com"],
      "time_window": {
        "start": "2025-07-24T09:00:00Z",
        "end": "2025-07-24T17:00:00Z"
      }
    },
    "expires_at": "2025-08-30T23:59:59Z",
    "not_before": "2025-07-24T00:00:00Z"
  },
  "signature": "ed25519-signature-hex"
}
Technical approach:
- Ed25519 signatures for cryptographic verification
- Self-contained delegations (no external key lookups)
- Time-bounded with automatic expiration
- Hierarchical scope system with wildcard support
- Standard constraints: spending limits, time windows, domain filtering
Full spec and reference implementation -> github dot com slash krisdiallo slash aaip-spec
This feels like where OAuth was in the early web, everyone solving auth differently until a standard emerged. What approaches are you taking? to building AI agent rails? to managing/updating existing constraints?

Hey everyone,
I'm excited to share a brand new side project I just finished building: phototopixel.art. It's a simple web tool that automatically converts any photo you upload into pixel art.
I've always been a fan of the aesthetic of pixel art, but manually creating it is a tedious process. After trying out some existing tools and not being fully satisfied with the results, I decided to build my own. My goal was to create a fast and easy-to-use solution that consistently produces great-looking pixel art.
Behind the Scenes
The core of the tool uses a combination of color quantization and pixelation algorithms. When you upload a photo, the system analyzes its color data and reduces it to a limited palette, while simultaneously creating the iconic blocky look.
One of the biggest challenges was fine-tuning the balance between preserving key details and achieving a genuine pixel art feel. I experimented a lot with the algorithm to find the sweet spot, allowing users to choose different settings to get the perfect result.
Potential Uses
Avatars: Make a unique, retro-style profile picture for social media.
Digital Art: Turn a favorite photo of a landscape or pet into a cool piece of pixel art.
Game Assets: It might even be useful for indie developers looking to quickly generate simple assets or mockups.
I’d love for you to give it a try and share your feedback. What features would you like to see added? Are there any use cases you can think of that I haven't mentioned?
Thanks for checking it out!

Hello HN,
I'm a solo founder, and for years, I've seen a recurring problem in the startup world: while AI has made brainstorming incredibly accessible, the output is often a raw, unstructured chat transcript. Great for initial ideation, but when it comes to turning those ideas into an actionable plan or a shippable strategy, I'd end up spending hours manually extracting insights, organizing them into coherent documents, and building execution steps.
I built IntutivAI to solve exactly this. It's designed to be your AI co-founder, transforming your high-level goals into an actionable, structured workspace you can genuinely act on. Instead of endless chat logs, you get scannable blocks of insight and a concrete execution plan.
What it does:
When you tell IntutivAI a goal (e.g., "analyze competitors for my SaaS," "validate my idea," "improve user retention"), it processes it and presents the output in an organized canvas. This canvas is broken down into Groups (like 'Competitors', 'Go-to-Market Strategy', 'User Personas', 'Key Risks') and Boxes within those groups, each containing concise, well-formatted markdown. It's built for rapid comprehension and iteration.
Crucially, it also generates an Execution Plan with concrete, sequenced steps, including checklists and 'Do it with AI' tasks. These AI tasks let you generate first drafts of content (like ad copy or email sequences) or structured analyses (like competitive breakdowns) directly within your plan. You can then refine or accept these outputs, keeping all your insights and progress in one place.
What's different:
The core difference is structure and actionability. Most AI tools give you a firehose of text; IntutivAI gives you a ready-to-use framework. It's engineered to be a strategic partner that helps you move from vague prompts to concrete execution, reducing the manual effort of organizing raw AI output. It's also designed to be concise and, if needed, challenge your assumptions based on established business frameworks.
How to try it:
You can try IntutivAI directly here: https://intutivai.com
We require a quick, minimal onboarding process to give the AI context about your project (your stage, what you're building, your role). This context is crucial for the AI to provide relevant and personalized strategic advice. There's a free tier available for you to experiment with, with no credit card required to start.
I'm a solo founder and built this from my own need. I'm keen to hear your thoughts, feedback, and any challenges you encounter. What could make it genuinely indispensable for your workflow?

I built a diffusion model that generates Tetris gameplay frame-by-frame, similar to Google's GameNGen/Genie but designed to run completely in your browser using ONNX.js. No servers, no APIs – just pure client-side neural frame generation.
The model is still in early training — this is just the first step. I plan to extend it to more games next.

I was trying to build a website for sharing robotics projects and realized the coolest way to visualize a robot is in 3D.
I could only find a few open-source projects that did this, but each was for a specific environment (think MJCF vs URDF vs USD) and some were damn hard to run. I know Next.js so I decided to merge them all and call it mechaverse.
I wanna fix bugs and make the viewers faster so please test it and break it.

value: The implementation is purely static, agents are added via PRs, and updates are made via CI. Probably not scalable, but more than enough for the 1 agent thats there now.<p>Any one know if there are other A2A agents in the wild that I can index here?

Hello HN,
I had submitted my website link sometime back but submitting again after many tweaks. https://embit.ca started out for me to check tech news every morning and several times a day, then few friends found out and started using it. It still has small audience but whoever has used finds it useful. I would appreciate some feedback from HN folks as there is lots of room for improvement without making it too complex. Thanks
The website is at https://embit.ca
