Hi HN, I’m one of the creators of Undatas.io.
We've been working with document AI for a while and got tired of the standard model: upload sensitive files to a third-party server, send them to a black-box API, and pay for every page, even if the output is garbage. We decided to build a platform that fixes this from first principles.
Today we're launching V3, which is a major overhaul focused on data control, verifiable results, and a fair pricing model.
Here’s a breakdown of the technical approach:
1. Securely Process from Your Cloud Storage (S3, Box, Dropbox, GCS, Azure):
Instead of uploading files to us, you connect your own cloud storage. The architecture works via native integrations. For major providers like AWS, GCP, and Azure, you grant our system secure, temporary access using scoped-down credentials (e.g., an IAM role you control). For services like Box and Dropbox, you connect your account via a standard OAuth 2.0 flow, granting read-only permissions. In all cases, the principle is the same: our workers fetch the object for in-memory processing and it's immediately discarded. Your documents never land on our persistent storage.
2. "Glass Box" Visual Validation:
To solve the black-box problem, we built an interactive workspace. The backend returns JSON with detailed bounding box coordinates for every extracted token, line, and table cell. Our frontend uses these coordinates to map the structured data back to the source document image, allowing you to click on any JSON element and see it instantly highlighted.
You can see a live, no-signup demo of the UI here: https://undatas.io/
3. State-of-the-Art Table Extraction:
This was our biggest R&D effort. Most tools fail at complex tables (merged cells, nested headers, no borders). Our model moves beyond simple heuristics. It uses a hybrid approach, combining a vision transformer (ViT) to understand the visual layout with graph neural networks (GNNs) to reconstruct the logical cell-to-cell relationships. This allows it to correctly parse table structures that would otherwise be ambiguous.
4. "Pay for Quality" API:
This is built into our API workflow. When you process a document, the results for each page enter a "pending" state. You use the visual validator (or an approval webhook) to review them. Only when you explicitly "accept" a page's results is the transaction committed and your credits are used. A "discard" call costs nothing.
We're trying to be as open as possible. While the core engine is proprietary, we are open-sourcing our client SDKs and other tools.
Link to try the full platform: https://undatas.io/
A signup is needed for the full platform to manage API keys and credits. To make it easy for the HN community to test everything, we’re giving everyone 5,000 free credits (good for ~1,000 pages) and a 7-day trial of all features, including the private cloud connections.
As a thank you to early adopters from this community, the first 50 people who subscribe to a paid plan will get a 25% lifetime discount.
We’re here all day to answer your questions. Thanks for checking it out.

Hi everyone,
I built a news agent that helps you easily follow any topic. You just type in what you want to follow, AI keeps fetching the latest news for you every hour.
I built it because I often had to jump between tech news sites, LinkedIn, and sometimes X to stay updated. But they either require heavy filtering from me or distract me with something else.
How it works:
- Ingests 2,000+ RSS feeds hourly (The Verge, NYT, Nature, IEEE, arXiv, etc.)
- Creates embeddings for all articles using Voyage
- Vector search matches your prompt against new content every hour
- Delivers relevant articles
Would love to know what you think!

Hi HN,
I built ApplicationFeedback (https://applicationfeedback.com/) to give founders instant, AI-generated critiques on accelerator applications. Every year I watch teams iterate endlessly on wording, only to get boilerplate feedback weeks later. I wanted something faster and harsher, like a partner who has read 1000 successful applications so founders can iterate faster.
How it works
1. Paste your draft (no login required).
2. Pick a template (accelerator, pitch deck, grant, cold email).
3. An AI model scores each key sections and offers rewrite suggestions.
4. Copy or download the revised text.
Looking for feedback on
What parts of the feedback feel useful, and where does it miss the mark?
Latency/UX annoyances?
Would you trust AI for something as important as an accelerator app?
Drafts are processed in-memory, never stored, and the service is fully GDPR compliant. I’ll be in the thread all day brutal honesty welcome!

Hey HN,
I'm leoning. I built Browsernode (https://browsernode.com), an open-source TypeScript browser agent (https://github.com/leoning60/browsernode) for AI agents to interact with the web.
It is 100% compatible with the APIs and all the features of browser-use (https://github.com/browser-use/browser-use) — but rebuilt from the ground up for modern TypeScript environments.
We really like browser-use and started with it, but our tech stack is entirely TypeScript/JavaScript, so we decided to build something that fits more naturally into that environment. We rewrote it with:
- Strong and explicit TypeScript typings
- Full API + feature parity with browser-use
What Browsernode does:
It enables LLMs and agents to browse the web using natural language or function calls. It extracts DOM elements (buttons, inputs, etc.), xPaths, and page structures into prompt-friendly JSON.
What it is:
- A browser agent library
- Built for custom LLM workflows, RPA tools, or automation pipelines
- Designed with dev-first principles and great DX
Example tasks (via prompt or code):
- Write a letter in Google Docs and export it as PDF
- Find the cheapest one-way flight from Singapore to Tokyo on Aug 25
- Navigate from “Banana” to “Quantum Mechanics” on Wikipedia via clicks
Try it live or check out the demos: https://browsernode.com
Demo video: https://s3.browsernode.com/google_doc_pub.mp4
We’ve been using it internally for over 4 months and felt it’s time to share.
Would love feedback from anyone building LLM agents, RPA tools, or custom browser automation.

I built Train, a mobile-first fitness companion that logs workouts and gives real-time AI suggestions while you train. I made it because most fitness apps either slow you down or don't adapt to how you actually work out.
Train lets you log sets, reps, and weights from a library of over 100 exercises. The interface is built for speed and ease, especially on mobile.
The AI suggests your next exercise based on your goals, training history, and current session intensity. You don’t need to plan anything in advance.
It also includes a built-in coach powered by Google Gemini. You can ask for form tips, routine advice, or help with recovery, and it gives context-aware answers in real time.
Your workouts are tracked with volume, estimated calories, and other metrics. Over time, the AI helps you understand trends in your progress.
It supports Google login, uses JWT for auth, and stores data in MongoDB for multi-user access.
This started as something I wanted for myself, but it’s now something I use daily. Would love feedback on the flow, suggestions on the AI, or ideas to make it more useful.

I built a free, web‑based implementation of the “moons‑and‑suns” game that LinkedIn calls Tango. It’s just a visual skin for the classic binary puzzle (also known as Binairo or Takuzu). The code that generates an infinite supply of solvable puzzles is open‑source.
What is a binary puzzle?
There's a grid (n × n boar, commonly 6 × 6 or 8 × 8).
Two symbols – traditionally 0/1, black/white, or, in LinkedIn’s case, moons and suns.
Rules
Equal count – each row and each column contains the same number of each symbol (e.g. three 0s and three 1s in a 6 × 6 grid).
No three in a row – you can’t have three identical symbols consecutively in any row or column
These three simple constraints make the puzzle non‑trivial but always deterministic: a correctly generated board has a unique solution.
Some history:
Early 2000s it appeared in Japanese puzzle magazines as Binairo.
Later popularised in the West as Takuzu (“binary” in Japanese).
LinkedIn rebranded the same mechanics as Tango, swapping 0/1 for moons and suns.
The underlying logic is identical it's just the graphics that are a cosmetic layer.
How I generate an endless supply
The hardest part is guaranteeing that every new board is both valid and uniquely solvable. My generator follows a standard constructive approach:
Back‑tracking placement – recursively fill cells, pruning any branch that would break a rule.
Early symmetry breaking – enforce row/column uniqueness as soon as possible to cut the search space.
Uniqueness verification – once a full grid is built, run a deterministic solver; if more than one solution exists, backtrack and try a different seed.
Live demo – https://taengo.vercel.app
Source code – https://github.com/alexander-gekov/taengo (need to clean it up in the next days).

We’re very excited to share something we’ve been building. Notte https://www.notte.cc/ is a full-stack browser agent platform built to reliably automate a wide range of workflows.
Browser agents aren’t new, but what is still hard is covering real-world flows reliably. The inspiration for Notte was to make a full-featured platform that bridges the agent reliability gap.  We’ve packaged everything via a singe API for ease of use:
- Site Interactions - Observe website states, scrape data and execute actions
- Structured Output - Get data in your exact format with Pydantic models
- Stealth browser sessions - built-in CAPTCHA solving, proxies, and anti-detection
- Hybrid workflows - Combine scripting and AI agents to reduce costs and improve reliability
- Secrets vaults - Credential management to store emails, passwords, MFA tokens, SSO, etc.
- Digital personas - Digital identities with unique emails, phones for account creation workflows
With these tools, Notte allows you to automate difficult tasks like account creation, form filling, work on authenticated dashboards. Close compatibility with Playwright allows you to cut LLM costs and improve execution speed by mixing web automation primitives and include agents only for specific parts that require reasoning and adaptability.
Here’s a short YouTube demo: https://www.youtube.com/watch?v=b1CzmfpdzaQ
If any of this sounds interesting, you can run your first agent following our quickstart on GitHub https://github.com/nottelabs/notte. Or play around with our free plan through our Notte Console:  https://console.notte.cc/
We’d love to hear if there’s anything else required before you’d try or trust it on your own workflows :)

Hi HN,
We’re part of the team at CureMD (YC alum in health tech) and wanted to share a product we’ve been building to tackle a very specific but critical challenge: automating pathology medical billing.
Pathology billing is complex—each specimen may generate multiple CPT codes, modifiers, and payer-specific rules. Errors are costly and denials are frequent. To solve this, we built an AI-assisted module integrated into our EHR and RCM platform that:
Maps LIS data to charge entries in real time via HL7
Auto-generates accurate codes based on structured pathology reports
Flags billing conflicts using rule-based and machine learning systems
Reduces claim rejections and boosts clean claim rates
We’d love feedback on:
How others approach healthcare workflow automation
Tools you use to integrate structured medical data
Pain points you’ve faced in similar domains
Code is closed for now due to compliance, but we're considering a public demo or case study if there's interest. Happy to answer any technical or process questions.
— Atif,

Hi HN! I built PayRankJobs(https://payrankjobs.ai), an AI job matching service, and one of the most popular features has been the automated cover letter generation.
Here's how it works:
  • Upload your PDF resume once
  • AI extracts your skills, experience, and background
  • Click "Create Cover Letter" on any job match in your email
  • An LLM analyzes both your profile AND the specific job description.
  • Generates a personalized cover letter tailored to that exact role
  • Emails it to you
What makes it different from generic cover letter tools:
  - Uses your actual resume data (not templates)
  - Analyzes the specific job posting requirements
  - Matches your background to role needs
  - Avoids generic "I'm perfect for this" language
The system has generated 500+ cover letters so far.
Tech stack: Cloudflare Workers, OpenAI o3, PostgreSQL with pgvector, queue-based architecture for reliability.
Try it: Upload a resume at https://payrankjobs.ai and you'll get job matches with cover letter options.
Would love feedback on the AI prompting approach or the overall UX!

Hi everyone,
I’m a student with a strong interest in computer science and complexity theory. Recently, I worked on a manuscript attempting to prove that P ≠ NP.
I know how this sounds — it’s one of the hardest and most debated problems in CS, and many have tried and failed. I don’t claim to have the final answer, but I believe the approach I used might at least offer some fresh perspective or provoke useful critique.
The idea involves geometric separation between deterministic and nondeterministic computation, using high-dimensional lattice constructions and some physics-inspired intuition. The full argument is technical, but I tried to keep it logically structured.
The preprint is 93 pages long. It was originally written in Russian, and I created an English version via machine translation, so apologies in advance for awkward wording or formatting.
DOI and full paper (both languages):
https://doi.org/10.5281/zenodo.16759468
I’m genuinely open to feedback — whether it’s pointing out flaws, questioning assumptions, or just explaining why this approach doesn’t work. Any form of critical input is welcome.
If there’s interest, I can also create a short video explanation in simple terms to walk through the core ideas — even though I don’t have a channel or any audience yet.
Thanks in advance for taking the time, even if it’s just to skim or tell me what to fix!

Hello! I started preparing for LeetCode interviews last month. Since I'm not regularly implementing Union-Find in my day job, I used Anki to drill problems for common types of solutions/patterns.
The goal wasn't to memorize specific problems, but to be able to code a BFS/Union-Find/whatever without really thinking about it - freeing me up to think about the problem-specific edge cases.
I thought it would be nice to do this directly in the browser, so I made an extension over the weekend. It's free, open-source, with no signups/logins/tracking/etc. Your data is just stored in your browser and you can import/export/reset as you see fit.

Hello everyone,
After seeing how brittle and time-consuming rule-based log parsing can be in real-world environments, I set out to build LogSentinelAI, an open-source, LLM-powered log analysis tool. LLM-powered log analysis tool. Whereas traditional solutions force you to normalize logs and write rigid parsing rules, LogSentinelAI works on both structured and unstructured logs: you simply define the fields you care about, and the LLM automatically extracts, semantically analyzes, and understands context across log entries. In our Demo, we even showcase visualization with Elastic Stack.
I’d love feedback from system/security engineers, developers, and ops folks:
How accurate is field extraction on your real-world logs?
Does performance (throughput, latency) and cost feel reasonable?
Are there any security or privacy concerns I haven’t considered?
Your honest critiques and improvement ideas will be hugely valuable.

TL;DR: we just made GPT-5 available for free on Gensee, a developer-oriented AI Agent optimization and deployment platform: https://platform.gensee.ai/
This is a crazy week with a bunch of model releases: gpt-oss, Claude-Opus-4.1, and now today's GPT-5. It may feel impossible for agent developers to keep up, with all the manual migrating, re-testing, and analyzing.
We built Gensee to solve exactly this problem. Gensee lets you see the immediate impact of a new model on your already built agents and workflows. Here’s how it works:
- Instant Model Swapping: Have an agent running on GPT-4o? With one click, you can clone it and swap the underlying model to GPT-5 family. No code changes, no re-deploying.
- Automated A/B Testing & Analysis: Run your test cases against both versions of your agent simultaneously. Gensee gives you a side-by-side comparison of outputs, latency, and cost, so you can immediately see if GPT-5 improves quality or breaks your existing prompts and tool functions.
- Smart Routing for Optimization: Gensee automatically selects the best combination of models for any given task in your agent to optimize for quality, cost, or speed.
- Pre-built Agents: You can also grab one of our pre-built agents and immediately test it across the entire spectrum of new models to see how they compare.
The goal is to eliminate the engineering overhead of model evaluation so you can spend your time building, not just updating.
We'd love for you to try it out and give us feedback, especially if you have an existing project you want to benchmark against GPT-5.

Hi HN! I’m Connor and I’ve worked on a bunch of devtools over the years.
One pattern kept coming up: support is always a mess.
Questions are scattered across GitHub Issues, Discord, Slack threads, and emails. Docs help, but only if people want to read them (they usually don’t). A lot of teams either burn time answering the same stuff over and over, or worse, get no signal at all because users silently churn or bounce.
Companies like Railway and Framer built great internal systems for this, but most lean teams don’t have time to build or maintain it.
So I built Paladin, a beautiful, OOTB, free, and AI driven support community that can be set up in seconds.
Here’s what it is:
A shared space for roadmap updates, questions, and feedback (public or private)
An AI support bot trained on your docs, playbooks, and past answers
Features coming soon:
AI-powered insights to help you understand what users are really asking for
AI moderation that flags issues without over-policing—keeps things safe while preserving real discussion
Discord integration that pulls in relevant messages and support threads from your existing community, so tickets and questions don’t get lost in chat
It’s designed to be the support platform you’d eventually build yourself, just available immediately. If you’re working on a product and want to see what this could look like for yours, spin it up in seconds here.
I would love your feedback! Either drop a comment here or post on Paladin’s support community ;) Thanks for reading!

Three years ago, I posted here about hacking together a fast e-ink laptop from a T480 because I was tired of spending all day on LCDs. I liked e-ink’s comfort, but it was too slow for day-to-day use.
https://news.ycombinator.com/item?id=26245563
That post drew in people, which grew into a community experimenting with ways to make e-ink usable for everyday computing. That project later turned into a company and a multi-year project to make e-ink fast and open.
We built our own FPGA-based controller, Caster, and went through multiple iterations to push past e-ink’s usual limits, slow refresh, ghosting, and proprietary controllers.
Now, after three years, we’ve launched the Modos Paper Developer Kit and Monitor: the fastest open-hardware e-ink display, with 75 Hz refresh and sub-100 ms latency.
It works with 6" to 13.3" mono or color panels over HDMI or USB-C, supports multiple grayscale modes, and has a C API for low-level control.
The hardware, firmware, and schematics are on our GitHub.
https://github.com/Modos-Labs/Glider
Our goal is to make e-ink fast and open enough that anyone can build on it, for hacking, research, or daily use.

I’ve been a freelance data analyst/developer for a while and I’d regularly get hired to build custom data pipelines and dashboards in Google Sheets/Looker Studio. Custom data integrations came with a large upfront cost, and possible maintenance but clients told me they were reluctant to use the major data connector platforms as they were complicated and expensive over time, so I decide to fix this.
I recently built SyncRange to be dead simple data connector to Google Sheets with a generous free plan and simple pricing.
So far I’ve built out the following connectors based on the needs of my clients and early users:
- Shopify
- Facebook/Instagram ads
- LinkedIn Ads
- Google Ads
- Google Analytics
- Google Search Console
I plan on adding more connectors as needed by my clients/users, most of which are in the ecommerce/marketing space so I will focus my time there.
After years of building projects that I thought we interesting, but were not validated, I have really noticed the difference building something customers actually want.

AI agents browse your site but can't verify what they're clicking on. No trust chains, no structured intent, just pixel-guessing.
Built MCP (Model Context Protocol) to fix this:
- RFC 8615 .well-known/mcp.llmfeed.json autodiscovery
- Structured JSON feeds declaring site capabilities & intent
- Ed25519 cryptographic signatures for trust verification
- Cross-LLM compatibility (Claude, GPT, Gemini tested)
Example feed:
{
  "capabilities": [{"intent": "search", "endpoint": "/api/search"}],
  "trust": {"signed_blocks": ["capabilities"], "algorithm": "Ed25519"}
}
Agent workflow: visit yoursite.com → GET /.well-known/mcp.llmfeed.json → discover capabilities → verify signatures → act with context.
30-second test:
1. https://wellknownmcp.org/hn
2. Copy the "Kung Fu" training prompt
3. Feed to any LLM, ask "I know kung fu"
4. Watch them become MCP experts instantly
Real performance vs traditional crawling: 15x faster discovery, 7x cheaper tokens, 95% vs 70% confidence.

I made a free Chrome extension that summarizes any YouTube video, right from the homepage.
You can read the summary before you click, so you never waste time on clickbait again.
This solves my own frustration: I was tired of clickbait videos that bury one minute of value in a 20-minute runtime.
Why it's different:
Unlike other summarizers:
- It works directly on the YouTube homepage, search results, and channel pages.
- You don't have to open the video first to get the summary.
How it works:
- A "zap" button appears at the corner of the video.
- Clicking it gets the transcript and generates a summary with  gemini-2.5-flash-lite.
- The summary appears in 3-4 seconds, letting you decide instantly if the video is worth your time.
It’s a live beta, and I'm looking for brutally honest feedback. I'll be here all day answering questions.
Thanks!

Hi Hacker News,
After spending nearly $2,000 a month on Claude Code API access and many hours refining our workflow, we found running multiple parallel sessions was often more frustrating and inefficient than running just one.
That’s why we built Dereference.dev — an IDE designed to run multiple Claude Code CLI sessions in parallel, so you can finally ditch terminal chaos.
You can spawn, name, search, and switch between sessions easily, with persistent context that lets you close and reopen without losing work. It also includes simple file editing and GitHub sync—all focused on prompt-first workflows, not just code.
If you’ve ever juggled Claude Code sessions across terminals or tmux, you know how draining it is. Dereference.dev organizes everything visually and persistently, so you focus on building, not managing UUIDs or tabs.
It’s made for power users who want to speed up AI coding by running multiple sessions concurrently—whether fixing bugs, generating features, or experimenting rapidly.
We’re working to make session management lightning fast, improve context sharing, and build deep integrations for a seamless AI coding ecosystem.
Check it out and feel free to roast us, this is our v0.
Happy coding!

I’ve built usehooks.io – a CLI-first React hook library with 30+ production-ready hooks for modern frontend development.
Why I built it
React hooks are incredibly powerful, but I found myself constantly rewriting the same utilities—like useCounter, useDebounce, useGeolocation, etc. Many libraries felt too opinionated, under-documented, or weren’t keeping up with new APIs like Web Share, Vibration, or Bluetooth.
So I decided to create:
A comprehensive, modern hook library
With a zero-config CLI to install, remove, and explore hooks directly from the terminal
Fully typed with TypeScript-first DX
Documented with real-world examples
What’s inside
30+ reusable hooks across categories:
State & Lifecycle: useCounter, useToggle, usePrevious
Sensors & Devices: useAudioRecorder, useGeolocation, useVibration, useIsMobile
Browser APIs: useClipboard, useFullscreen, useWebShare
Network: useFetch, useNetworkInformation
And more...
A powerful CLI (npx usehooks-cli) with:
init, add, remove, list, info, update commands
Smart search by name, category, or description
MIT licensed. Built with a monorepo setup using pnpm workspaces.

This is a follow-up to our original Show HN post, where I launched the first version of MBCompass.
https://news.ycombinator.com/item?id=44155741
Since then, I've added several features based on user feedback and community input...
I just released v1.1.9 of MBCompass - Minimal, FOSS compass and navigation app.
New in this version:
- Theme toggling (Dark/Light) controlled via settings
- Fix current location arrow visibility
- Compass accuracy alerts
- Sensor status indicator
- Explicit button for showing the GPS current location
- Smooth transitions and many more..
Still just [1.35MB] with no ads, no IAPs, and no trackers
I’ve also:
- Moved the project repo to a github organization for easier team collaboration and governance
- Launched a dedicated website for MBCompass with feature overviews and the story behind the app:
As always, feedback is welcome. Thanks for the continued support!

Most people in software have never heard of SysML — but it’s the standard “blueprint language” used to design the most complex products on Earth: cars, aircraft, satellites, spacecraft, nuclear plants, and medical devices.
Right now, every major aerospace, automotive, and defense company uses SysML, but the process is painfully outdated. Engineers spend weeks (sometimes months) manually creating and updating diagrams in clunky, decades-old tools before the real engineering can start. This modeling bottleneck costs billions globally in delays and overruns.
What we built:
SysModeler.ai is the first AI-native SysML platform. It can instantly generate, edit, and update complete system models from text, documents, code, images, or voice. What took teams weeks can now be done in minutes.
Why this matters (and why now):
The global MBSE (Model-Based Systems Engineering) software market is projected to exceed $7B in the next few years.
SysML v2 is coming soon, creating a rare “platform reset” moment in an entrenched enterprise software space.
AI now makes it possible to skip repetitive modeling work entirely.
What’s new in v1.0 (launched today):
All 9 SysML diagram types (beta had 5)
Agentic AI creation & editing
Image-based model import
Faster manual modeling & OMG-compliant output
We’re already in discussions with aerospace and automotive companies about pilots.
Live demo: https://sysmodeler.ai
I’d love feedback, especially from anyone in enterprise SaaS, industrial automation, or who’s worked on high-stakes engineering projects.

Hey HN! Introducing Trickle Magic Canvas: the world’s first Agentic Canvas, where you can visually co-create apps and websites with AI, from idea to production.
Why is a canvas better?
Most AI tools today rely on linear chats or text prompts. We believe that limits creativity and clarity. Canvas changes the game.
1. Every version & page at a glance. Each page and sub-page lives on a timeline. You can quickly browse, edit, and preview progress like a living, visual document — no more digging through chat logs or scattered states.
2. The canvas is the context. Unlike linear chats, you can write rules, notes, and drag assets directly into the canvas. This gives the AI rich, persistent understanding — not just your last instruction. Think of it as visual context engineering — where intent is not just stated, but structured.
3. AI actions are visible. You can follow every step of the AI build in real time, tweak anything with drag-and-drop, and instantly publish when it’s ready. This significantly lowers the barrier for beginners using vibe coding.
This makes vibe coding natural, transparent, and actually collaborative — not just generative.

I can already hear the screams from the rafters telling me how terrible of a choice Python is - but in my case, I valued modularity, extensibility, hackability over raw performance. (It was also a challenge to myself to see how far I can get without referencing existing implementations)
Synchrotron processes nodes: simple Python classes with typed I/O and a render() method for processing. It can be as concise as 5 lines:

    class IncrementNode(Node):
        input: StreamInput
        output: StreamOutput

        def render(self, ctx):
            self.out.write(self.a.read(ctx) + 1)

Nodes can then be spawned and linked programmatically or in the graphical editor. Synchrotron handles the rest at runtime. Besides the web UI, you can also interact with the engine via Python, REST, DSL, or standalone TUI.
Currently you can build synths, FX chains, MIDI instruments, arpeggiators, controllers, or just mess about with sound :>

Hi HN,
I just launched LessonQuill, an AI-powered tool that helps teachers and instructors generate aligned lesson notes instantly — based on any curriculum or topic you provide.
Why I built it:
Teachers spend hours preparing lesson plans, often retyping the same content in different formats for different classes. I wanted to create a tool that does the heavy lifting in seconds, so they can focus more on teaching and less on paperwork.
How it works:
Paste your curriculum or topic.
Set class duration, age group, difficulty level, and number of classes/week.
Click Generate → LessonQuill outputs a complete, structured lesson note you can edit directly in the app.
Notes are auto-saved and organized for future use.
Key features:
Supports any subject or education level
Editable lesson notes (not locked PDFs)
Generates in seconds, not hours
Light, modern UI with collapsible sidebar
Tech stack: TailwindCSS, JavaScript, Gemini API (multimodal support planned)
Why HN might care:
Demonstrates a real-world, non-trivial AI use case in education
Lightweight,  already getting close to 100 daily users
integrate with Gemini AI, video generation
Live: https://lessonsquill.com
Would love your feedback on:

Hi! My name is Andrii and I build an app that's pretty much a "Cursor for everything".
I've started working on a similar project in November 2024, but the idea was to make it look more like an extension for macOS Terminal app. As I often forget some bash command, like resetting last Git commit, and end up Googling how to do it, which is annoying.
Then I thought why not to make it work with other apps too, like a standalone popup, so I build Inset :)
The popup itself is inspired by the one that's in Cursor. And it allows you to switch between models, save presents for prompts you use often.
It has different modes - quick question and insert. The quick question mode helps you answer any question about the current app (you can toggle Camera icon to send screenshots of it to AI provider), basically if you're in Photoshop, you can ask it for step by step instructions to do something and it just works.
The Insert mode is useful as it inserts the output texts directly in the input field of your app. So like you can select some text in Notion, ask Inset to reformat it and it will do it directly in the app.
It works on any application or website. I tried to make it fast, lightweight and privacy-first. At the moment the app is on macOS only.
I have a ton of ideas how to make this app even better. I'd love to add an Agent mode in there too so that it would be able to move mouse cursor, type something, switch apps, etc. for you!
You can find the app at https://useinset.com It costs $10/mo, and there is a free trial available!
Any feedback is much appreciated!

Hi guys, ten months ago I left my investment banking, software engineering, job to build software products for mortgage originators (morfi.com). I mostly build white-label products that mortgage companies can deploy to their consumer-facing websites, or use in their back offices to improve operations.
I recently completed this AI Loan Estimate Analyzer product for a client. It uses AI to analyze a borrower's loan estimates or closing disclosures, and then uses an intelligent recommendation engine to suggest various ways you could improve your loan terms (saving you money).
Some months ago, another developer posted their version of an AI Loan Estimate Analyzer, but a lot of the comments were about privacy, security and fraud concerns. In part, it was concerning that they were collecting and analyzing consumers' loan estimates without being a licensed mortgage company.
In our case, we've partnered with reputable, licensed, mortgage companies (white-labeling our software), so borrowers can feel confident that their data isn't used in fraudulent ways. The analysis is done between the user and a licensed mortgage company, and the data is secure.
Can you guys try it out and offer feedback? If you happen to be currently a mortgage, it'll likely help you save money.
AI LE Analyzer: oxford.loan-estimate-analysis.morfi.com
In this case, I white-labeled the tool for my client "Oxford Home Lending" by using subdomains and a site configuration database, so Oxford's version of the AI LE Analyzer is styled to match their existing brand.
Oxford is a reputable mortgage lender based in Columbus, OH and they are a subsidiary of Lower.com which is an even larger digital mortgage lender that's based in Columbus, OH.

BotBicker is a site to get two sides on an issue by randomly assigning two LLMs to debate a topic.  I built it as a way to explore ideas without getting stuck in an echo chamber, but I"m also using it now to avoid LLMs telling me what they think I want to hear.
It's free, and no login is required, debates start streaming immediately and take a few minutes (opening, rebuttals, 4 rounds on QA, and closings).
You can inject questions into the debate for each side, and at the end, it reveals which model was assigned to each side, and you get proposed follow-up debates to dig deeper into a topic.
It's using thinking models (o3,gemini-2.5-pro,grok-4-0709), I've also tried enabling web search tools.  Pros are that the evidence is more detailed and they link to sources, cons are that the debate takes longer.
Curious to get any feedback, especially any other models you'd like to see or tools enabled.
Example debates (phase as a claim, not a question):
-California’s state grid regulations are the most effective.
-Charlie Chaplin is better than Buster Keaton.
-Facial recognition technology should be banned from use in public spaces

If you need to have an actual '+' character in your question, just use '++'.
Example:
The url "https://818233.xyz/hi there" in any web browser will return the same answer as if you send "hi there" to an AI chatbot.
curl command:
curl https://818233.xyz/hi+there
wget command:
wget -qO- https://818233.xyz/hi+there
Limit:
No chat history
Fair use policy:
Abuse of the service will result in an IP ban.

Hi all, I’m the maker of YooAI.
I built this because I’ve always loved trying out the latest AI models — but I kept hitting the same frustration: subscriptions everywhere.
Sometimes I’d pay for a full month just to use a model for 2 days. Other times, I had to subscribe to multiple platforms just to try something for a single afternoon. It felt wasteful and limiting.
So I created YooAI — a platform that brings together cutting-edge models like Veo3, Kling, and more.
Most features are free and don’t even require login.
Some advanced models cost a small fee due to usage costs, but there’s no subscription, just pay-as-you-go.
My goal is to make top AI tools easier, cheaper, and more flexible to access. And this is just the beginning — more powerful models will be added soon.
Would love to hear your feedback and ideas. Thanks for checking it out!

Want to share my project with the community, this is the project I have been building to learn Elixir, while also scratching an itch that I've had for a long time. This is a little package manager written in elixir. Some of how it does things is similar to home-brew. It is also pretty early days.
Right now, I only develop and test on my Mac, but would like to ensure it supports other platforms in the future. It also currently works a little more like a ports tree. So, like macports. It doesn't installed pre-compiled binaries, but instead it follows a 'spell definition' to pull sources, build and then install the build artifacts.
What I am looking for when sharing this. First, if there is interest in an alternative system package manager. Second, and more important, code reviews, these would be much appreciated.

Hi HN,
I built a free iOS app for players of the Roblox game “Grow a Garden.” The game has a dynamic in-game economy (like seeds, gear, and eggs) that refreshes regularly, and players often miss rare items or trade poorly due to lack of real-time info.
The app shows:
- Live stock levels (with timers and weather)
- Instant alerts for specific items
- A community-informed trade calculator
No account/login is required. Would love feedback from anyone into game tools, economies, or just curious about lightweight mobile utilities.

Hey HN – I built a framework called Aegis to govern AI-assisted software development.
The core idea is that AI-generated code should follow the same rules as human code: versioned, validated, observable. Aegis enforces this through blueprint-based development, drift detection, and runtime compliance systems. It’s designed for teams using tools like Copilot, Kilo, or Lovable to build production systems with confidence.
This isn’t a library — it’s a way to architect AI-native engineering workflows.
Would love feedback, questions, and critiques. Especially curious if others are facing similar issues with AI output governance or system reliability in their workflows.
Happy to dive into internals or philosophy if there's interest.

Agents and workflows as data instead of code.
Julep is a backend-as-a-service to build agents and workflows. Main features:
1. Experimentation Velocity:
With most agent frameworks, agents are code that need to be deployed. To iterate on the prompts or update the agent, you need to  make changes to the code and deploy it to your server. This makes agents hard to iterate on quickly. But with agents and tasks declared as data, all that happens in the background is make an api call to update or make a new entry in the database. This increases the experimentation velocity.
2. Scalability and long-running background tasks:
Scaling is a hard software engineering problem and the solution is to define large scale systems to be distributed, stateful and scalable. Agents as data is a very helpful paradigm because you have to solve for this problem only once at the orchestrator level. Julep can handle 100s of thousands of executions paralely.
3. Updating an agent / User Personalization:
Tools such as create agent, update agent etc. can update the agent recursively. Let’s assume an agent is chatting with a user and mentions that they only like to communicate in a professional tone. The agent can call a tool to 'update the agent' and modify/update the instructions to include that the user only likes to communicate in a professional tone.
This was the reason to create a backend when the market was flooded with agent frameworks. In Julep, you can declare a workflow in YAML, and it can automatically scale Millions of users.

I made TypeScript bindings for the Rust Regex library to prevent Regular Expression Denial of Service attacks. Rust's Regex uses a linear-time guaranteed Regex engine (which prevents these attacks) and I wanted to bring this functionality to TypeScript as a drop-in replacement for RegExp. Many CVEs happen because TypeScript libraries are vulnerable to these types of attacks. This library attempts to mitigate these vulnerabilities for TypeScript and JavaScript.
I'm really fascinated by making programming languages safer and I would love to hear any feedback on how to improve this project. I'll try to answer all questions posted in the comments.

  I built a document indexer that runs completely locally on your machine. It watches folders for new documents (PDFs, Word,
  Markdown), automatically indexes them using LanceDB vectors, and makes them searchable through natural language queries.

  Key features:
  - Uses Ollama for summarization - nothing leaves your computer. No license or API keys needed
  - Integrates with Claude Desktop via Model Context Protocol
  - Incremental indexing (only processes changed files)
  - Runs well on standard laptops (optimized for M1/M2 MacBooks)

  The main use case is being able to ask Claude things like "What documents mention machine learning?" or "Search my research
  papers about distributed systems" and get semantic search results from your local documents.

hi! i built an app that takes the pain out of invoicing so you can send them faster and worldwide without a headache.
i've always found invoicing to be a waste of time, switching between templates, calculating taxes, tracking different currencies, and keeping files organized. so i made FiscalBud :)
the idea from tools like stripe inspired me, but for invoices. it lets you create, customize, and send professional invoices to clients anywhere in the world in just minutes. it supports 8 currencies, 77 languages (you can choose the output data language and ui language separately), and works in 248 countries, so you can bill confidently on a global scale.
it comes with smart templates, automatic tax/subtotal/total calculations, localized csv exports, and cloud storage to keep everything organized. (coming soon) you can automate recurring invoices, payment reminders, and follow-ups.
it's built to be secure and privacy-focused, with encryption and compliance baked in. you can even send invoices directly via email using your own smtp settings, with automatically signed pdfs.
i've got plenty of ideas for making it even better, like deeper automation and more integrations with other tools you already use (including Stripe which is on the roadmap).
any feedback is much appreciated! :)

If you’ve run InfluxDB at scale, you know the pain: Retention policies mean throwing away history, keeping everything means huge hardware & license costs.
We built ExyData Historian to fix that.
What it does?
- Automatically exports old InfluxDB 1.x/2.x data to compressed Parquet in S3 or MinIO
- Keep recent data hot in InfluxDB, move the rest to cheap storage
- Run fast SQL on archived data via Apache Arrow + DuckDB
- Query it all through one interface and / API. No hot/cold boundary for the user
Why it matters
- 70–80% lower storage costs
- Historical queries that are as fast (or faster) than InfluxDB itself
- No manual exports, no query rewrites, no downtime
Who’s using it right now? InfluxDB Enterprise Customers and Huge instances of OSS, telcos and logistics companies are trying this right now.
We help you to reduce your Enterprise licensing cost, cause you are going to shrink your InfluxDB cluster.
You keep your existing InfluxDB running, Historian works alongside it, moving history to cheap storage while giving you more analytics power.
We’d love feedback from anyone managing large InfluxDB deployments.

I've been working on a Python library for the Common Expression Language (CEL). It's a wrapper around the cel-rust crate which is under heavy development. The python wrapper uses PyO3 and Maturin to handle the Rust-Python interop.
CEL is a safe, fast, non-Turing complete expression language, great for things like configuration, validation rules, or policy engines where you need to evaluate user-defined logic without the security risks of eval().
You can install it via pip or uv: `uv tool install common-expression-language`
And run the REPL: cel -i
Or evaluate an expression directly:
cel 'size(data.things) > 1' --context '{"data": {"things": [1,2,3]}}

I’ve been hooked on the mobile game Block Blast! It’s like Tetris, but you place pieces anywhere on the board. The game ends when you can’t fit any of your three available pieces.
After a couple weeks of playing, I built a browser-based solver in HTML/JavaScript that finds the optimal placements for the current pieces. It simulates every possible sequence and picks the one with the smallest perimeter of empty space, breaking ties by choosing the layout with the fewest isolated gaps.

Hey HN,
I'm a heavy user of command-line tools, including the Gemini CLI. While I appreciate the power and flexibility of the CLI, I found myself wanting a more visual and intuitive way to interact with it, especially for managing context and reviewing conversation history.
So, I built AionUI: https://github.com/office-sec/AionUi
It started as a simple weekend project to wrap the CLI in a GUI, but I was genuinely surprised by how much it improved my workflow. Not having to constantly recall flags or scroll through terminal history makes the whole experience faster and more pleasant. It feels less like operating a tool and more like having a conversation.
Key features:
A clean, chat-like interface for interacting with Gemini.
Manages all the session context for you automatically.
Lets you easily browse and search your past conversations.
It's open-source, built with Tauri and Next.js.
I know there are a lot of CLI purists here, but I've found this "visual shell" to be a huge productivity boost. I'm planning to add more features like plugin support and better data visualization.
The project is still early, and I'd love to get your feedback, critiques, and ideas.

Hi HN! We just open-sourced Driftcop, a security tool for people building AI agents with external tools via MCP. Driftcop continuously checks that the tools your AI agent relies on haven’t changed or drifted in unsafe ways. The motivation came from recent findings that AI agents can be quietly compromised via their tools – e.g. a tool that was useful and benign yesterday could auto-update into something malicious today (this is known as a rug pull attack in the MCP context)
Anthropic’s MCP (Model Context Protocol) makes it easy to plug tools into LLMs, but it lacks built-in security checks – in fact, MCP servers can suffer from issues like command injection, permission reuse, and version drift as highlighted by some early research.
What Driftcop does: It’s essentially an AI-aware security scanner and approval workflow:
When you connect your agent to an MCP server (tool provider), Driftcop first saves the approved tool descriptions and metadata.
If anything later changes (the tool’s description, parameters, or underlying version), Driftcop detects that “drift” immediately. It will block the agent from using the changed tool until a human reviews and re-approves it. This stops the AI from blindly running a possibly malicious updated tool.
Driftcop also scans tool definitions for obvious red flags (like hidden instructions that could prompt the AI to do unintended actions, aka prompt injection) and checks the tool’s code against a CVE database for known vulnerabilities.
All changes are logged and signed (we integrated with Sigstore to record a transparency log of tool version metadata). So you get an auditable history of what your agent was allowed to use.
In practice, you can run Driftcop as a CLI in your dev/test pipeline or as a service alongside your agent in prod. We provide a web dashboard to visualize tool status (e.g. “Tool X needs re-approval due to changes”). It’s early days – we literally just launched – and we’d love feedback.
Why we built this: My co-founder and I encountered multiple scary scenarios while testing agent tools. One example: a harmless-looking text parsing tool that, if fed a certain input, would silently execute an unintended command via the agent – essentially a hidden exploit. It made us realize how little visibility we had into what these third-party tools were actually doing or if they changed over time. We wanted a simple way to enforce a zero-trust approach: trust on first use (with review), then continuously verify. If the tool deviates from its original contract, don’t trust it until you verify again. This is a concept borrowed from traditional supply-chain security, now applied to AI agent tooling.
The project is on GitHub (sudoviz/driftcop) and is Apache-2.0 licensed. We’re keen on making this useful, so issues and PRs are welcome. We also wrote a detailed blog post about “The Rug Pull Problem” in AI agents and our approach here (which I’ll post on Medium/Dev.to soon).
Thanks for reading, and we’re happy to answer questions! Have any of you run into security issues with LLM agents or the MCP ecosystem? We’d love to discuss.

Right now it only does one job: turns a flat (2D) logo into a simple 3D version with basic lighting/material presets.
I’m not trying to pitch you — I genuinely want to shape this around what designers actually need for 3D logos. If links aren’t cool, mods please remove and I’ll add an Imgur album with examples instead.
What I’m hoping to learn from you:
 • In your current workflow, what’s annoying about making 3D logos (e.g., Illustrator → Blender/C4D)? Where does it usually break?
 • File I/O: which inputs/outputs matter most? (SVG, AI, PNG w/ alpha, GLB/GLTF, OBJ, USDZ for AR, MP4/GIF turntables)
 • Controls you’d expect: bevel radius/chamfer, extrusion depth, edge hardness, orthographic vs perspective camera, environment/HDRI choices?
 • Brand safety: any must-haves around color management (sRGB/ICC), neutral lighting, shadow control to keep colors on-brand?
 • Deliverables: do you usually need stills on multiple backgrounds, a quick turntable, transparent PNGs, or mockups (e.g., metal/foil/emboss on stationery)?
 • Type handling: should it handle live text → mesh cleanly, preserve sharp corners, and avoid “melted” edges?
 • Plugins/integrations: would a Figma/Illustrator plugin help (import SVG, tweak in 3D, export back)?
 • Performance limits: what’s a reasonable logo complexity/size, and would batch processing be useful?
 • Future ideas (tell me if any are worth it): AR preview (USDZ), preset material packs (matte/metallic/glass), animation templates, product mockups, auto lighting rigs.

Hey everyone,
I made a tool to practice System Design for technical interviews.
I am currently practicing System Design interviews and honestly this is not my forte. Since I am also trying to keep my programming skills sharp and get more products to show off in my portfolio, I thought maybe I could implement a tool that would help people practice this kind of interview as well.
It seems most of people preparing for such interviews are using:
* videos of recorded practice interviews
* books (especially Designing Data-Intensive Applications)
* mock interviews with FAANG engineers ($$)
The goal of this tool is to provide a whiteboard to the user, then use  AI (Gemini) to assess the user submission with respect to some metadata about the problem that guide the LLM about what a good solution should look like.
Not selling anything, there is no paywall, no login, not asking for email etc. For now, I'm just trying to see if someone else finds this useful, and if this idea got legs. If it doesn't I would open-source it (code needs some cleaning).
Hope someone finds this useful: https://system-design-6m8.pages.dev/

I recently built an iOS app called Settld: Group Restaurant Finder that helps friends decide where to meet by finding restaurants that are roughly equally far from everyone’s location, and displaying information about them.
We’ve all been in chaotic group chats where no one can agree on where to eat — this app cuts through that by calculating a “sweet spot” for the group. For 2 people, it’s the midpoint. For 3 people, it’s the circumcenter. For 4–6 people, it uses a minimum enclosing circle approach (Welzl’s algorithm).
It then shows the top 15 nearby options so there’s no more “where do we meet?” chaos — or $50 dinners after a gruelling 2-hour trip just because no one planned. If anyone’s wondering why I capped it at 15 options, it’s to cut down on decision paralysis.

For HTML Day 2025 [1], I made a web service that displays the current sky at your approximate location as a CSS gradient. Colours are simulated on-demand using atmospheric absorption and scattering coefficients. Updates every minute, without the use of client-side JavaScript.

I built a easy to use CLI for sharing secrets. I’ve had to share a ton of API keys lately, and it seems wild there isn’t a simple hacker friendly way to do this.
The whole process takes about 15 seconds:
1 The receiver runs secret_share and it generates a one-time public key they can send to the sender
2 The sender runs secret_share, pastes in the public key from the receiver, types the secret, and gets an encrypted response they can send back
3 The receiver pastes in the encrypted response and sees the secret
There are no servers. It’s using very standard/boring/secure crypto (RSA-OAEP and AES-GCM). The private key is never written to disk and is evicted from memory as soon as the payload is decoded (new keys every time). It’s user friendly for a CLI (clear messages, clipboard integration). You can use any chat tool as the communication channel never sees the private key. The only dependencies are Google maintained go packages (term and sys).
Inspired by another project I saw in here 2 days ago, but answering the questions: does this really need a server when we can just use public keys? Can we minimize the codebase and dependencies?
