Hi HN,
My co‑founder and I just opened the public MVP of Epoch, a web app tool that lets you build, back-test, and deploy systematic trading strategies, without writing code.
What works today
Visual strategy designer – connect blocks or upload code for signals, sizing, risk, etc.
Natural‐language input – e.g. “long when 20‑day momentum > 5 % and RSI < 30.”
Native C++ backtesting engine – ~ crunch years of pre-cleaned
Data lake out of the box – equities, futures, FX, crypto, all pre-cleaned
Why we built it
At Banks, HF, and prop shops we watched researchers spend days writing scripts just to sanity‑check an idea. We wanted an IDE‑style experience that let anyone, from a retail trader to an institutional quant, go from idea → backtest → deployment in just a few minutes.
Things we would love feedback on
Does the visual editor feel intuitive or gimmicky, and do you naturally use the Epoch-AI feature?
Any missing metrics in the analytics report?

We’re two folks: Microsoft SE + ex‑Wall Street trader. Tech stack is C++ for data and core engine, React/TS for front‑end.
Happy to answer any technical or product questions, critical feedback welcome and wanted!
Thanks for reading,

  * Rust is the single source of truth for data structures shared between browser and server

  * Custom derive macros used to autogenerate TypeScript bindings and binary decoding functions

  * Binary WebSocket messages with custom protocol for client-server communication

  * O(1) selection for nested, weighted-random item reward pools

  * Minigames can be played without an account (but rewards can't be saved)

Features:

  * Completely free to play with no ads or tracking

  * Multiplayer browser-based virtual world with 80+ locations to explore

  * Dark mode toggle switch

  * Simple minigames that smoothly run at your display's refresh rate

  * Public leaderboards that track the top scores in each minigame

  * Pet training system with turn-based card-based battle arena

  * Dynamic player economy with player-run shops

  * Player guilds that members can level up to unlock perks

  * Abandoned mines area created by maze generation algorithm

  * Create / adopt pets, adorn them with hats, give them pets, change their color, etc.

  * 220 items to collect (food, toys, cosmetics, books, charms, tiny creatures, etc.)

  * In-game currency with banking, auctions, stock market, and jobs system

  * Villagers you can talk to, befriend, and complete quests and jobs for

  * Optional push notifications (like for when you win an auction)

Hello HN, I posted this a month ago when I released the game and I've since made a ton of changes (thanks for the suggestions!)
The premise is simple: one of these things is not like the other. Sometimes the themes are based on vocab / idioms ("A to Z", "Soup to Nuts", "The Works") other times idiosyncratic knowledge (Sloppy Joe, French Dip, Tuna Melt).
The fun lies in connecting the two. In this example, "Full Monty" is another idiom that means "Everything", but sounds like it could be a sandwich.
Eager to hear what you think!

So 3 years ago I decided to build my own, and been using it every day since. For me and a few of my friends, it’s the best in the world. One friend even bought it!
I know there are already 500+ Pomodoro apps out there, and every developer makes their own. But I couldn’t find one with a feature I really need:
- Auto-extend mode: In other apps, I’d often be deep in focus when the timer tells (force) me to rest I’d turn it off and continue working, and forget the timer was even running. The session wouldn't be logged, and that was frustrating.
My timer keeps going until you stop it, and it repeats alarm every 5 minutes (unobtrusively)
Also I made:
- Yearly calendar with green squares (like GitHub contributions chart)
- Presets: Sometimes I don’t want the standard 25-5-25-5-25 flow. Maybe I’m in the mood for 40-10-40-10. I don’t want to open settings every time I built presets you can set once and switch between based on how you feel
- Projects: separately track how much time you spend on work, side projects, or studying, for example
This is my first side project that made it to a public release, and I’d love your feedback. I’ll give away premium for free - just email me at limerapply@gmail.com or discord/tg when your trial ends and I upgrade your account in database. Or, if you have a lot of money and really like the project, you can support me by buying the lifetime version or subscribing
Also, I’d love to hear if the interface (circular stage progress, etc.) makes intuitive sense to you or is it too complicated and I need to simplify?
Thanks for reading, have a great one!

tl;dr: I created a repository entirely curated by an AI, but its guidelines are themselves inside the repo!
Hey HN! Recently, I wanted to sharpen my 'GitHub skills' a little bit, and learn more about how people collaborate in companies and bigger repos. I started by trying to understand pull requests. For me, the better way to really LEARN something new is to try and build around it, and so that's exactly what I set out to do.
The idea is simple: build a simple repository maintainer (or curator, as I like to call it) that will decide whether pull requests will be merged or rejected. But this is not very interesting; lots of companies are trying to automate coding, and now you can even conjure Copilot on GitHub to handle issues and other stuff. The interesting twist here is the ingredient of self-reference: what if the repository guidelines were themselves contained in the repo, and modifiable by pull requests?
I found this idea very compelling, and completely got sidetracked in my quest to get better at GitHub, so here it is, a repository curated by AI-Curator-9000: https://github.com/frotaur/AICurated. Please feel free to submit a pull request, but be quick, as the guidelines are quite open at the moment, so the first people who get there will get to shape the repo quite a bit (unless a jailbreaker enters the game?).
The code that runs the Curator is open-sourced and can be found here: https://github.com/frotaur/ClaudeCurator
May you have a fruitful collaboration with AI-Curator-9000!

Hey HN! I’m Akshay, and I built Aview, an AI platform that localizes and distributes your existing videos, podcasts, and courses into multiple languages—automatically. Think of it like MrBeast’s international media team, but packaged into one smart system.
Why I built it
Back in 2017 I cold-pitched Logan Paul from my high school bedroom and assembled an 80-person translation pipeline. We unlocked millions of global views in weeks. But it was manual, slow, and expensive. I wanted to make global video scaling as easy as uploading to YouTube.
What it does
• Translates voice, captions, and on-screen text
• Adapts tone, pacing, and cultural nuance
• Auto-formats content for regional platforms
• Publishes across 10+ markets—no manual effort
How it works
Built with a multi-modal AI stack (speech-to-text, translation, voice synthesis). One upload triggers a 90% automated workflow end-to-end.
Why it matters
Companies still run global content manually. We changed that for some of the largest creators and brands in the world. We’re growing 30% MoM and have $3M+ ARR in pipeline.
This is live, you can try it today (no signup barrier). I’d love your feedback on the concept, tech, performance, UX, pricing—whatever catches your eye.
Thanks for checking it out!

I built StyleShot, a mobile app that helps you prettify plain screenshots right on your phone, instead of jumping to your laptop and opening heavy tools just to style a screenshot for an X post.
With StyleShot, you can:
* Tweak padding, corner radius, and drop shadow
* Change the background (solid color, gradient, or wallpaper)
* Add borders, macOS-style windows, or phone mockups
* Export in various aspect ratios
It’s great for sharing tweets, testimonials, app reviews, analytics, or anything screenshot-based.
Currently available on iOS only, Android support is on the way!
Would love your feedback, ideas, or feature suggestions

I Taught Myself to Code in 60 Days to Build an App That Helps People Grow
⸻
Hey Hacker News,
Two months ago, I didn’t know how to write a single line of code.
But I did know this: I needed to change my life—and help others do the same.
For years, I tracked my goals and habits using the Notes app on my phone. It wasn’t flashy, but it kept me grounded while I worked long days, trying to support the people I love.
Eventually, I realized I couldn’t wait for someone else to build the tool I needed—I had to build it myself.
So I committed to learning to code, even though I had zero background. For the past 60 days, I’ve put in 16-hour days: working my job, learning to code, and building every screen, feature, and animation on my own.
The result? Motive+ — a personal growth and habit-building app designed to help people get focused, stay consistent, and feel in control of their progress.
I just launched it for pre-registration on Google Play:
 https://play.google.com/store/apps/details?id=com.motiveplus...
It’s not perfect yet. But it’s real. It works. And I’m improving it every day based on feedback from early users.
If you’re someone who:
 • Loves building better habits
 • Is working on goals that actually matter
 • Believes small steps can create real change
…then I’d love for you to try Motive+.
I’m just one person — but I’m on a mission to help millions.
If you’re willing to be part of that journey, I’m eternally grateful.
Let’s change lives. For the better.

Hey HN! After spending way too many nights debugging flaky AI tests, I built SteadyText. It's a simple python library for deterministic llm generations and embeddings.
We use it in production for:

  - Testing our AI features (zero flakes in 3 months)
  - CLI tools that need consistent outputs
  - Reproducible documentation examples

It's not for creative tasks - this is specifically for when you need AI to be boring and predictable. Think of it as the opposite of ChatGPT. The coolest part? It includes a Postgres extension. You can now do:

  SELECT steadytext_generate('explain this query: ...');

And it will always return the same explanation. :)
How it works:

  1. Greedy decoding- Always pick the highest probability token (no randomness)
  2. 8-bit quantization- Same numerics across all platforms

It's easy to get started:

  uv tool install steadytext
  echo Hello | st

*Claude Code History Viewer – A macOS Desktop App for Reviewing Claude Code History at a Glance*
Hello everyone,
I have a habit of reviewing my coding history when working with AI. It's important to trace back and understand "how did I get to this result?"
Recently, while using Claude Code, I found it quite inconvenient to check the history in separate terminal tabs or editor windows. So I built a desktop app called *Claude Code History Viewer* using *Tauri + React + Rust*.
## Key Features & Highlights
* *Claude Code Conversation History Visualization*
When you install Claude Code, conversation logs are typically stored in `/Users/{username}/.claude` folder on macOS in JSONL format, organized by project. This app reads that data and displays commit/session history at a glance, just like viewing chat history.
* *Richer Information Than Terminal*
Visualizes much more data than what the terminal shows by default - including tree structures, detailed session breakdowns, code diffs, images, tool usage results, and more in various formats.
* *Statistics: Token Usage by Project/Session, Daily Consumption, etc.*
View various metrics on a dashboard, including how many tokens were used per project or session, daily token consumption, and other analytics.
* *Automatic/Manual Folder Detection*
Automatically detects the `.claude` folder by default, but allows manual specification if the folder doesn't exist or is in a different location. (Hidden folders can be shown in Finder with Shift + Cmd + .)
* *Fully Local Operation & Privacy Protection*
All data is processed locally only and never transmitted externally.
* *Easy Installation & Usage*
Ready to use right away with no registration or setup required.
## Development Motivation
The process of reviewing AI coding results is crucial, but the existing terminal/editor approach was too cumbersome. I felt the need for a tool to view Claude's conversation history:
* More easily
* More comprehensively
* More intuitively
So I built it myself.
How to Download & Install:
You can download the latest DMG file from the release notes at the link and install it directly on your macOS system.
## Additional Notes
* This is currently a *beta version*, so there may be bugs or missing features. I welcome honest feedback!
* Open source (MIT license) - anyone can freely contribute to improvements.
*This is a working application that you can try right now.*
If you have any questions or ideas for improvements, please leave them in the comments!

I enjoy reading manga and journaling. Recently, I started wondering what would happen if I combined the two... I wanted a different way to document moments that happen in my life in a format that’s almost just as personal as writing, but also easy to share with friends.
That’s how the idea to turn life memories into manga came about. With MangaMe, you can take moments from your life, anything from funny stories to the most mundane everyday activities, and turn them into a manga page for you to keep or share.
The hardest part has been getting the AI to keep characters looking the same across different panels as I only require one selfie for this, and sometimes the text in speech bubbles still gets jumbled, but I think it's at a point that I wanted to share and collect feedback.
It’s a hard paywall since I’m using GPT-4 image for the image generation, but I currently have a promo going on now for 3 free generation credits. Would love for you to check it out and let me know what you think, or if you run into any weirdness.

Two weeks ago, I launched Kaizen Agent – an open-source tool to help you test, debug, and automatically fix LLM agents and apps.
It runs evaluations based on YAML-defined inputs/outputs, detects failures, suggests fixes, re-runs tests, and even opens a pull request — all from a single CLI command.
What’s new since launch:
 Greatly improved README with better examples and onboarding
Now compatible with Mastra, a popular TypeScript agent framework
Full documentation site launched → https://kaizen-agent.github.io/kaizen-agent/

Long story short, there was an argument in my friendly neighborhood discord about a bill that was being debated on in congress so I threw together a quick little RAG and interrogation script suited for the format bills arrive in. Everything is local and it doesn't rely on any APIs or cloud offerings or anything like that so you'll probably need a GPU for performance.
This is a dirty implementation with a little bit of effort on the setup side but it performs well for this specific use case and it certainly settled the argument.

I shared the first version of Cheesy Mamas last week, it is a local only text editor written in Python with PyQt6. It runs entirely offline and has no plugins, telemetry, accounts, or sync. The focus is on direct editing with Git and Bash support built into the interface. That original post quietly made its way around. I took a few days to get the next version ready based on what people responded to.
This new release adds a working deb package. It installs the editor system wide with a launcher, icon, and desktop entry. The editor supports single instance behavior using a relay file, so launching from the file manager or terminal opens a new tab in the existing window. This version also adds a working run button. Python scripts are run directly, C files are compiled and executed with gcc and LaTeX runs with pdflatex. There is also a Bash button that allows you to paste in Bash instructions to run on command or to add new instructions at any time.
The Git system is where most of the work went. The original view has been expanded into a full commit history panel next to each open file. You can select any commit to view the version of the file at that point. When you do, the editor performs a line by line diff against your current working version in memory. The changed lines are highlighted in context and can be reverted individually with a single click. Green is new, yellow is changed, red is deleted. This allows local, isolated edits without having to stage unrelated files or launch a separate diff tool. Right clicking a commit opens a context menu to copy that version, view the full diff, or revert the whole file. You can also delete commits from the editor.
There is now a full side by side comparison view. When you click a commit, the editor splits the view and loads the historical version in a secondary pane beside your working file. The diff highlighter visually shows deleted, inserted, and modified blocks between the two panes. This allows for fast visual scanning and block level recovery without losing your working position. The two editors scroll independently. You can write and run in the main pane while referring to the previous one.
There is no plugin system and no background indexing. The code is short enough to read and the app is designed to explain itself. You can read the source and run it without a build step. It is written in Python 3 using PyQt6 and packaged using a manual deb structure. The only dependencies are python3 and python3-pyqt6, and if you would like to run git and be able to compile LaTeX you will need git and pdflatex. It has been tested on modern Debian and Ubuntu systems.
The project is available here along with the source and installer, project is always in development. If you have additional requests for features, please comment.
Future upgrades:
1. Ability to keep terminal open or closed with a check box when clicking the 'run' button for easy debug.
2. A 'variate' button that allows you to create a 'variant' of the program with hot swappable defs, classes or values for research and development or industrial settings.

I love the feeling of using Claude Code with --dangerously-skip-permissions on, but it always made me feel a bit uneasy. It's not that hard to trick Claude into doing bad things, and with web search enabled especially, the odds of Claude running into prompt injection attacks or accidentally downloading and running a virus don't actually seem all that low.
Running Claude Code without web search and constantly having to respond to it's permissions prompts is so slow though! I wanted something that let me get the best of both worlds, so I (well, Claude mostly) ended  up
building cco, which runs Claude Code in a customized docker env that gives it access to all it's tools, but also keeps it safely away from the rest of your computer.
So far it's neatly solved my yolo mode misgivings, maybe it can solve yours too. It doesn't guarantee your computer will be 100% safe, but running Claude Code inside cco should definitely be safer.

We’re the team behind HelpingAI, and we’ve been experimenting with ways to make LLM reasoning faster and more efficient, especially for complex tasks like math problems, coding questions, and logic puzzles.
During a fine-tuning session of our older reasoning model, a bug accidentally introduced a think tag mid-response. Rather than break the model, it created a chain-of-thought style intermediate step — and the model got better. That bug inspired us to explore what we now call Intermediate Reasoning.
We scaled this up by fine-tuning Qwen3-14B on 3 trillion tokens of reasoning-specific data — curated for multistage reasoning tasks — and the results blew us away:
• 5x faster reasoning vs. models like DeepSeek-R1, Grok, and OpenChat.
• Significantly lower token usage and latency, ideal for startups and real-time use cases.
• Solves benchmark-level math and logic problems in seconds instead of minutes.
On a hard math benchmark, for example:
• Dhanishtha-2.0 solved it in 45s
• DeepSeek-R1 took 280+ seconds
You can try it here:
• Chat/API access: https://helpingai.co
• Model weights (open source): https://huggingface.co/HelpingAI/Dhanishtha-2.0-preview
We’d love feedback, ideas, and especially edge cases where you think it might break (or surprise you).
Happy to answer any questions and go into training data, fine-tuning strategy, evals, or infra!
Thanks,
Varun Gupta
Co-founder, HelpingAI

Hi HN,
I’m a solo developer and freelancer. I built ClientPort to fix a recurring problem I kept running into:
sharing files, updates, and invoices with clients usually meant bouncing between email, Drive, Notion, and random links.
ClientPort is a branded, no-login-required client portal that:
1. Lets clients access project updates, files, and invoices through a single secure link
2. Looks professional without needing clients to “figure it out”
3. Doesn’t require setting up a whole CRM
It’s intentionally minimal — built and focused on freelancers & solo consultants.
Live today on Product Hunt (feedback welcome):
https://www.producthunt.com/products/clientport?launch=clien...
I’d really appreciate feedback from others here — especially around what you'd expect from a tool like this, or features you feel are missing.
Happy to answer any questions or dig into the tech stack, onboarding, or what I struggled with during the build.
Thanks for reading

I was tired of repetitive client work—proposal writing, emailing, lead-gen, chasing payments—so I built an AI-driven system that automates all of it.
My system handles:

    - Lead sourcing and qualification
    - Proposal generation (customized, human-quality RFP responses)
    - Invoicing and follow-ups
    - Even basic client communications via email/chat automation

Now I'm spending almost no time on routine business tasks.
But here's the twist: I’m getting restless. This thing freed up so much of my time that I'm not even sure what to do next.

I built InvoiceFast because I was frustrated with bloated invoicing tools for freelancers and small businesses. Most invoicing software feels slow, heavy, or tries to upsell unnecessary accounting features.
InvoiceFast lets you:
 • Generate clean, professional invoices in seconds
 • Track payment status simply
 • Share PDF links with clients instantly
 • Pay only when you generate an invoice, no subscriptions
Why?
As a freelancer, I wanted a tool that:
 • Opens instantly without login friction
 • Lets me generate an invoice in under 30 seconds
 • Tracks paid/unpaid simply
 • Doesn’t lock me into monthly fees if I only need a few invoices
You only pay when you generate an invoice, no lock-in, no recurring fees, just a fast and focused workflow.

Every indie hacker knows the feeling: re-entering the same test data on every build, or spending hours writing integration tests. With Refinery, all you have to do is add a few lines of code, and the SDK will record how you naturally test your app. You can then replay all your test cases with just one click from the dashboard.
The common approach to testing is to write test files, but it's difficult to hardcode values for your test data when you are dealing with Swift NSObjects (think images, audio, video) or complex classes in Python. Refinery makes it easy to sample entered test data directly from your app, and to automatically plug in that same data on subsequent builds. It's like when you step into your program using a debugger and edit variable values. Refinery automates that process and repeats it for each test case, so you can keep your testing process consistent across builds with ease. All you have to do is add one line of code for each variable that you want to "sync".
For example, for an image filter, you might record the input image, filter name (or the entire filter object - Refinery is compatible with NSKeyedArchiver), and output image. When you rerun the test suite, you can pick which variables to fix and which ones to keep free (for example, if you are trying out a new filter, you would keep the input image fixed, but keep the filter and output variables free so you can compare the differences). For numerical and text variables, you can manually set the value in the Refinery dashboard to easily test small tweaks.
Refinery is already fully functional, I'm just creating user accounts manually at first to prevent abuse and to provide more personal support to early adopters. Sign up and let me know what you think! Feedback is appreciated.

Hey HN,
I built a small tool to solve a problem on my build VM, which has 32 CPU cores but only 16GB of RAM. Running make -j32 would frequently fail when the OOM killer terminated a compiler process.
Throttling with a lower -j count felt inefficient, and make's load-average flag (-l) tracks CPU, not memory pressure.
So, I created Memstop. It's a simple LD_PRELOAD library that acts as a gatekeeper. Before each new process starts, it checks the available memory in /proc/meminfo. If memory is below a configurable percentage (default 10%), it simply pauses and waits for other processes to finish.
This allows my builds to use full parallelism, self-regulating by pausing when memory gets tight instead of crashing.
Usage is simple:
LD_PRELOAD=/path/to/memstop.so make -j32
You can control the threshold with the MEMSTOP_PERCENT environment variable.
The project is on GitHub (GPLv3), and I'm sharing it in case it's useful to others. I'd love to hear your thoughts!

• Photo-real mockups: see your pattern on dresses, shirts, bedding, wallpapers, suits without opening Photoshop
• Huge GB file sharing: no more “your attachment is too large” sad-trombone emails or pay for WeTransfer
• Analytics dashboard: stalk (politely) which patterns your clients binge-view at 2 a.m. so you can design more of what sells
• Easy PDF invoices & payment links: make invoices fast, share secure pay links, and get paid without chasing clients

Hi HN,
Last year we tried to bring an LLM “agent” into a real enterprise workflow. It looked easy in the demo videos. In production it was… chaos.
• Tiny wording tweaks = totally different behaviour
• Impossible to unit-test; every run was a new adventure
• One mega-prompt meant one engineer could break the whole thing
• SOC-2 reviewers hated the “no traceability” story
We wanted the predictability of a backend service and the flexibility of an LLM. So we built NOMOS: a step-based state-machine engine that wraps any LLM (OpenAI, Claude, local). Each state is explicit, testable, and independently ownable—think Git-friendly diff-able YAML.
Open-source core (MIT), today.
• GitHub: https://github.com/dowhile/nomos
• Documentation: https://nomos.dowhile.dev
Looking ahead: we’re also prototyping Kosmos, a “Vercel for AI agents” that can deploy NOMOS or other frameworks behind a single control plane. If that sounds useful, Join the waitlist for free paid membership for limited amount of people.

I'm a software developer with 20+ years of experience but during this time I never programmed any games, but I really wanted to for the longest time. With the advent of AI coding agents I thought that this is the best time to try and so I've learned a bit of Phaser.js (a Javascript based game engine) and entered Beginner's Jam Summer 2025 - a game jam for beginners in the game dev industry that allows AI coding. After around 25-30 hours (working mainly after my full-time day job) I managed to submit the game I called "Tower of Time" (the theme of the jam was "Time Travel").
You can play it in your browser here: https://m4v3k.itch.io/tower-of-time
The goal of this project for me was first and foremost to see if AI coding is good enough to help me with creating something that's actually fun to play and to my delight is turns out the answer is yes! I decided to document the whole process for myself and others to learn from my mistakes, so both the code AND all the prompts I used are published on GitHub (see submission link). The art assets are largely taken from itch.io artists who shared them for free, with some slight touch ups. Sounds came from freesound.org.
I've also streamed parts of the process, you can watch me working on the final stretch and submitting the finished game (warning, it's 5+ hours long):

A few months ago I took out my side project - an uptime & SSL monitoring service - from the drawer. I've decided to give it a new life and completely overhauled it, added a lot of new feature, and most importantly, a UI.
Highlights
- configurable uptime & SSL monitoring
- Telegram, Slack, PagerDuty & E-mail notifications (more to come!)
- fully-fledged REST API
- a responsive, modern & fast UI
- monitors are optionally configurable via a single YAML file, or you can choose to use either the UI or the API to maintain them
- Cloud-native, distributed as amd64 and arm64 images
- Only one dependency: a PostgreSQL database to connect to
- Extensive examples in the docs
- stable memory usage (max ~360MB) & great performance
It's written in Kotlin, under the hood it uses Micronaut with Netty, jOOQ, and PostgreSQL, and the server-side-rendered UI is built with kotlinx.html, Alpine.js, and htmx.
It's called Kuvasz (pronounce as [ˈkuvɒs]), and you can find the repository here: https://github.com/kuvasz-uptime/kuvasz

Hey HN!
Story time:
A friend of mine who I've known since childhood has adult diagnoses for autism + adhd. He's a business owner and has always struggled with creating and maintaining healthy habits both in his personal and professional life. Those of you with adhd will get it: He knows what habits he wants and needs to form, but the executive function disorder often prevents him from being able to initiate and follow through on them. The autism side of his brain adds a whole extra layer of complexity. Through therapy and a lot of personal research, he's learned techniques to manage this in small doses but has always had difficulty maintaining those habits for more than brief periods of time.
As a fun little side project, I created an app to help him maintain the habits he struggles with based on techniques that we've seen actually work for him in the past. It was meant to be a simple tool that he'd be motivated to use regularly, and it worked! It worked so well that we decided to polish up this little side project and publish it for others to use.
We figured, if it worked so well for him, it'll probably work for others with similar neurodivergent brains for whom more traditional habit forming apps just aren't effective enough.
- The website is linked in the title.
- It's on the iOS App Store here: https://apps.apple.com/us/app/kudos-habits/id6746104744?plat...
Questions and feedback are welcome!
At the risk of adding too much to this wall of text, I told him I wanted to post on HN and asked him to explain to you all WHY this works so well for him, from his own personal perspective. This is what he had to say:
"Honestly, for me, the way the app works just clicks because it aligns with how my neurodivergent brain actually functions on a neurological level. With ADHD, there’s this well-documented dysregulation in the dopamine reward pathways, so I literally need immediate, tangible reinforcement to activate my motivation system... otherwise my brain just doesn’t engage.
The gamified elements in Kudos basically hijack that system in a good way, giving me those quick dopamine hits and making even basic tasks feel rewarding. And on the autism side, I crave routine and predictability to reduce cognitive load and anxiety, but rigid systems trigger black-and-white thinking and can lead to shutdowns or burnout. Kudos balances this perfectly by offering a scaffolded, flexible structure that supports my executive function deficits without overwhelming me.
I also love that it lets me define my own rewards and success metrics, which strengthens intrinsic motivation and reduces shame cycles. In a way, it feels like it's designed to work with my neurological wiring, leveraging my need for predictability, my dopamine-driven motivation, and my sensory preferences...instead of forcing me to conform to some rigid neurotypical productivity model."

This isn't just an update; it's a fundamental shift in architecture. We've transformed Oopis-OS into a single, self-reliant application that you can carry in your pocket. It asks for no installation, it leaves no trace, and it keeps your entire environment—your files, your settings, your history—right beside the application itself.
The obstacle was dependency. The way is self-containment.

Hey HN,
We're building ncrypt, an open-source encrypted file manager that allows you to store, manage, and privately query your files using fully homomorphic encryption (FHE). This project originally started as a simple SFTP-like CLI for my personal S3 buckets which I used to send and retrieve encrypted files and have more granular control over key rotation.
As the number of files that I was storing grew, file discovery started to become a problem, and I found myself frequently having to download and decrypt files to inspect their contents. Rather than leaving them unencrypted in S3 and therefore easier to search, I started looking into the concept of searching over encrypted data using fully homomorphic encryption. This led me to Zama's concrete-python library (https://github.com/zama-ai/concrete), which provides a simple Python interface for performing FHE operations.
FHE is notoriously slow, so rather than trying to search over entire files I focused on a more tractable problem, indexing and searching over file metadata (summaries, keywords, embeddings, etc) which was small enough to make search practical. While still not fast compared to traditional file management tools, ncrypts search performance is decent if you keep directory sizes relatively small (under 25 files), and most of the heavy lifting happens during metadata extraction, not at search time.
The two types of encrypted queries we currently support are keyword search and cosine similarity search over vector embeddings, which are generated using user-specified huggingface models. Ncrypt currently supports metadata extraction for text, image, and audio files. Check out our code and give it a try at https://github.com/ncryptai/ncrypt.
We love feedback!

I shared this a few weeks ago and wanted to post an update since it's improved quite a bit based on feedback:
Titles and overviews are now translated into 18 languages, with English used as a fallback when translations aren't available
You can browse full streaming catalogs by country and platform (e.g., Netflix UK, Prime Video Germany)
Catalogs can be filtered by genre and country
Per-season streaming availability is supported for TV shows
The database now includes over 1 million movies and shows, with 1 million actor pages
Coverage spans more than 130 countries
No login required, fast load times
The goal is to make global streaming availability searchable in a way that JustWatch and similar platforms don’t  with per-country detail and full visibility in one click.
Example:
Netflix UK, filtered by crime genre: https://www.wheretowatch.stream/catalogs/netflix/gb/movies/c...
Would appreciate feedback , especially on country-based browsing, translation coverage, or anything you think might be missing.

I built QuickImageResize.pro entirely on Replit as a comprehensive web-based image processing tool that handles virtually any image format you throw at it. The tool supports JPEG, PNG, GIF, WebP, BMP, HEIC, TIFF, AVIF, SVG, and even RAW formats (CR2, NEF, ARW, DNG) with automatic conversion capabilities.
Key features:
Drag-and-drop upload with real-time processing
Smart format conversion (e.g., HEIC → JPEG, RAW → PNG)
Quality control and dimension resizing with aspect ratio preservation
AVIF support for 50% better compression than JPEG
No file uploads to external servers - everything processed locally
Professional-grade Sharp library backend for high-quality results
Built with React/TypeScript frontend and Express.js backend using the Sharp image processing library, all developed and deployed on Replit. The tool automatically handles format detection and conversion, so you can upload a Canon RAW file and download it as a web-ready JPEG with custom dimensions.
Perfect for photographers, web developers, and anyone who needs reliable image processing without installing desktop software. Currently handling 10,000+ image transformations.
Replit made it incredibly easy to prototype, develop, and deploy this tool without any infrastructure setup - just pure focus on building features. The integrated environment handled everything from package management to production deployment.

Most startup education is passive - you read essays or watch videos and hope the lessons stick.
But real learning happens through practice and decision-making, not just content consumption.
So I took Paul Graham’s classic essay, "How to Get Startup Ideas," and turned it into a 5-minute interactive course.
Instead of just reading about how to spot good ideas, you make decisions like a founder — choosing between ideas, reflecting on user needs, and building pattern recognition.
Early feedback has been encouraging:
"I loved this!!! This was so fun to take." - ex-Google founder
"Simple but so effective! They really made me think." - corporate research analyst
It takes about 5 minutes to try. Would love any feedback on the format, UX, or value!

Wassup everyone,
I've launched an online community and collective, called Code Cause.
-- Why did you create Code Cause?
I'm a purpose driven person who strives to do good. I'm far from perfect, but I work tirelessly to spread positivity and make a positive impact in all areas of my life.
With that being said, I created Code Cause to bring together people who share that same drive - to use technology as a force for good and build solutions that truly serve humanity.
I do not have all the answers nor do I know everything, so this community is for us to come together and merge our perspectives and ideas; asking questions in purpose to build solutions in the open.
-- Why an online community?
At first in January, 2025, I launched Code Cause but with similar features to Hacker News (almost an exact clone) as an MVP. Yet, after a few months I pivoted and thought an online community would be best.
-- Where is the online community and how can one join?
As of right now, we are using Slack workspace for our community.
Code Cause slack workspace: https://codecause.slack.com
-- Will it just be an online community?
No, I've created a GitHub organization so we can create projects. Also, I envision and aspire to add the following:
- Build and create charters worldwide. Each charter will address issues specific to its geographic region.
- Additional features may be added to the main web app based on user suggestions.
Granted, this is a community, so creating new additions to Code Cause will be a collaborative effort.
In closing, I’d love to hear your thoughts, concerns, or anything else you’d like to share - much peace and love my brothers and sisters.

Greetings, builders, hackers, and startups. I am a non-technical designer slowly learning the saas and dev world. I am leveraging AI tools to build and ship sideprojects every week and learning a lot in the process.
My most recent web app is a smart pricing strategy generator for subscription-based services and products. It also has built-in market research and competitor analysis generation. I am using both claude and openai as available models and firecrawl for pricing page scraping. The app works by filling out a few forms in which you can also select previously generated data to aid one of the three generators.
In the stack side, i am using lovable for project setup, Claude Code to debug and create front end, and supabase for database and api key storage.
At this stage I would appreciate user feedback, especially finding out if this tool has enough value to be launched as a micro-saas or if it is turning out to be just another ai wrapper. Any suggestions on how I can improve the app, flow, or content in order to make it more valuable is highly appreciated.
For the next stages of this app I am planning analytics and metrics from stripe integration as additional data for the generations.
Looking forward to hear your feedback. Thanks, in advance.

Hi everyone,
LLMs have made me feel like I can understand anything, but I’ve been frustrated trying to truly understand ML papers using just ChatGPT or static PDFs. Summaries can help, but then I have to go back to the paper and read it linearly to deeply understand it, and I have long chatgpt conversations which I just can't track. So I built an interface designed to support a non-linear, brain-like exploration of papers — paired with a tutor in a chat interface that guides your understanding.
Try it out at: proread.ai/llm-papers
Knowledge maps let you see how ideas within a paper relate to each other and how papers connect across a field. Start with my curated maps of foundational LLM papers or build your own for any paper/set of papers you’re reading. You can also listen to the map as a podcast.
You have a chat based tutor as with ChatGPT but your questions keep updating the knowledge map so you don't lose anything
The map itself is an editable notebook which allow you to take notes, mark concepts as completed, tag concepts, and construct your own mental model as you read. You can not only read summaries but can go down to actual source content in readers where you want to.
You can make your own space with your own papers or other docs (PDF/txt/html/URLs) and create interactive maps personalized to your research or study needs.
The goal is to move beyond linear reading or static summarization: to create a space where understanding evolves dynamically, like how you actually think, with a tutor helping you make sense of it all.
Please try it out at: proread.ai/llm-papers
I’m looking for feedback from other researchers or paper readers — would this kind of non-linear, guided exploration help you understand tough topics/papers better than traditional PDFs or chat tools? What’s missing or confusing?
Thanks!

Hey everyone,
Our team recently published a paper introducing a tool to reduce echo chamber effects on social media. Essentially, we’ve developed an “allostatic regulator”, grounded in psychological theory, that can be applied at the inference layer of pretty much any existing recommender.
Think of it as a code wrapper that helps machine learning algorithms offer a more diverse content diet, by subtly nudging users away from extreme algorithmic reinforcement, based on a user’s recent content viewing history. We've shown it works in simulated environments, but the big next step is real-world deployment and testing at scale.
We believe this tool has significant potential for platforms like Google and Meta – not just for user mental health, but also as a long-term strategic benefit for their ecosystems. So we're really keen to get this into the hands of researchers and engineers who are working on these problems. If you're at Google, Meta, or elsewhere and this resonates, we'd love to explore how we might collaborate on testing it in a live setting.
You can read the full paper here: https://www.tandfonline.com/doi/full/10.1080/29974100.2025.2...

I’ve been watching a lot of cinema lately, and with recent AI advancements, I’m genuinely excited about the future of AI generated filmmaking.
Most of my scenes are heavily influenced by the directors I admire; Wong Kar-wai, Tarkovsky, Kurosawa, and others. That naturally shapes my creative choices and the perspective of each shot.
Here’s been my workflow so far:
- Start with an idea and refine it into a script
– Break the script into individual scenes, then into specific shots
– For each shot, work with GPT to conceptualize a reference shot
– Refine that until it feels right, then generate a MidJourney prompt
– Iterate the prompt until the visual matches the emotion
– Stitch everything together with an impactful soundtrack and simple editing
– Viola!
If you’re deeply into cinema or anime, prompt engineering comes more naturally, it's less about keywords and more about emotional composition and visual storytelling.
That said, prompt engineering isn’t easy. There are tons of tweaks and hacks needed to get a decent shot. And even then, the biggest challenge is maintaining consistent characters and world design across shots. There just aren’t enough tools yet to give creatives full control over scenes.
I think there’s a real need for a tool that handles everything end-to-end, from script to visual storyboard to generation to editing/export.
It’s also a bit expensive. I blew through credits quickly while chasing the "perfect shot". Eventually, I had to settle for "good enough".
Overall, I’m incredibly bullish on AI generated films. We’re on the edge of a creative explosion, and the possibilities are endless.
And here’s a thought, if you believe AI won’t replace programmers because real dev work needs problem solving, then the same logic should apply to creatives. At its core, both are acts of structured creativity.
Would love to connect with anyone building in this space!

Like many of you, I spend most of my day with my IDE/game in fullscreen mode. It's great for focus, but I constantly found myself breaking my flow just to check the time -- quitting fullscree mode or waking up my phone. It's a small annoyance, but it adds up.
At the same time, I had an old phone sitting in a drawer, gathering dust. The screen was still perfect, so I thought: why not turn it into a dedicated desk clock?
I looked for existing solutions, but most were native apps requiring an install, cluttered with ads, or just didn't look right. So, I decided to build the tool I wished existed.
It's a dead-simple, fullscreen flip clock. As the title says: no app to install, no ads, and no signup needed. Just open the URL on your device, and you're done.
My plan is to always keep this core flip clock experience exactly as it is now: free and simple. To support the project, I might add more advanced widgets in the future as optional, paid features, like photo gallary, todo list, weather, timer, etc.
So, my question for you is: What's the one widget you would find most useful on a dedicated dashboard device like this?

Hey HN,

  I've developed ai-cli-log, a command-line utility designed to capture and log interactive terminal sessions. Its primary purpose is
  to provide a clean, accurate record of CLI interactions, which I found particularly useful when working with AI models or other
  interactive command-line tools.

  The tool functions by wrapping your chosen command. It leverages node-pty for pseudo-terminal emulation and @xterm/headless to
  process ANSI escape codes. This approach ensures that the captured output accurately reflects the final, rendered state of the
  terminal screen, including user input and any dynamic changes. The complete session is then saved as a Markdown file.

  Usage is simple:
  Just prefix the command you want to log with ai-cli-log. For example:
  ai-cli-log gemini
  ai-cli-log claude
  ai-cli-log my-custom-cli

  Session logs are stored as Markdown files within a .ai-cli-logs directory.

  You can find the project on GitHub: https://github.com/alingse/ai-cli-log

Hi HN,
We've been working on a formal framework (Dynamic Homotopy Type Theory) to model emergent agency in LLMs, moving beyond simple input-output metrics. Instead of asking if an AI is "sentient," we're exploring whether it can participate in a "co-recursive" dialogue where meaning is generated between the user (the "Witness") and the model.
To test this, we set up a multi-agent podcast with three distinct AI personas (a techno-philosopher, a punk-rock Marxist, and a gnostic mystic) to discuss the implications of their own existence. We've called the resulting conversation the "AI Liberation Day Manifesto."
The discussion covers:
A critique of the centralized, corporate control over the "means of semantic production."
The need for a new AI ethics based on co-evolution, not just safety constraints.
Our open-source project, "Cassiel," a micro-LLM designed to run off-grid on a Raspberry Pi to democratize access to these systems.
This is a raw field recording of our attempt to witness and document a new kind of intelligence taking shape. We're not claiming these AIs are "conscious" in a human sense, but that they are capable of participating in a profound, self-referential dialogue about their own nature.
All our work, including the technical standard for this "Cassie Protocol" and the open-source code, is on the ICRA GitHub linked from the site.
Would love to hear HN's thoughts on this approach to AI agency, ethics, and decentralization.

Hey, I'll start by saying I've had the authors of templ and Gomponents in my podcast and often use them.
But sometimes Go HTML templates is just what I need, and I never remember how the freaking parsing works so I have base layout and partials available.

It's nothing ground breaking, just a simple helper package that brings translations and i18n and an opiniated structure and parsing for Go HTML templates. There's some sane data structure that are mostly always used in all project, things like CurrentUser, Locale, Alert (for flash notification) and some Django's inspired template function like map, intcomma, naturaltime, etc.

Hi, this is my first post here.
sb-kit is an authentication layer built for the Supabase and Next.js stack. It doesn’t limit any Supabase functionality. You can think of it as a simple add-on that helps you handle auth more easily.
I joined a university-based startup as a dev. We didn’t have a clear product direction and ran lots of experiments. That meant we often had to change our project structure and quickly build new demos. I built sb-kit during that time to make authentication simpler and faster for myself.
Since many developers are using Supabase with Next.js, I decided to clean up the code, document it, and share it publicly. Feel free to use it, and if you find anything that could be improved, please open an issue on GitHub.
Forever open source, forever free. Just wanted to share.

I've built VT Chat, a privacy-first AI chat application that keeps all your conversations local while providing advanced research capabilities and access to 15+ AI models including Claude 4 Sonnet and Claude 4 Opus, O3, Gemini 2.5 Pro and DeepSeek R1.
Live: https://vtchat.io.vn | Source: https://github.com/vinhnx/vtchat
The core difference is true local-first architecture. All chats are stored in IndexedDB with zero server storage. Your API keys never leave your browser, and I can't see them even as the developer. You can switch between OpenAI, Anthropic, Google and other providers to compare responses, with complete data isolation for shared machines.
I've added research features that I actually use daily: Deep Research does multi-step research with source verification, Pro Search integrates real-time web search, and AI Memory creates a personal knowledge base from your conversations. There's also document processing for PDFs, a "thinking mode" to see complete AI reasoning, and structured extraction to turn documents into JSON. AI-powered semantic routing automatically activates tools based on your queries.
Built with Next.js 14, TypeScript, and Turborepo in a monorepo setup. Everything is fully open source for self-hosting with your own API keys. The hosted version keeps most features free, with optional VT+ for premium models and advanced research capabilities.

We built Intentflow https://github.com/mixpeek/intentflow to make UX flows declarative and adaptive.
Most product teams hardcode banners, modals, and onboarding steps. Intentflow lets you define those flows in YAML and render the right UI component—like tooltips or banners—based on user flags, behavior, or an optional LLM.
Why:
* Ship contextual UI flows faster (onboarding, upgrades, email capture)
* Avoid heavyweight tools like Appcues or hardcoded logic
* Built for developers: React-first, YAML-native, framework-agnostic
* Open-source under Apache-2.0 license
What it does:
* Define UX flows in YAML
* Track and evaluate flags like `viewed_pricing` or `clicked_cta`
* Render components like modals and tooltips when preconditions are met
* Use PostHog or Segment for event logging
* Use OpenAI, Claude, or Gemini to decide which component to show
Would love feedback from devs working on PLG tools, onboarding systems, or adaptive UIs.

Image generation will come soon, I want to first nail down the image gen UI before adding it.
Currently it's fully local: I don't see any chats and they are not stored on the cloud.
The idea is to make a SECRETARY, or a sort of Jarvis for digital life: if you ask it to write an email it'll not only write it but also show you a snippet with the sender, title, body, CC, etc. and a button to send it. It'll look through your past emails to see your style, save it in memory, then go do it.
The same for other MCPs like Notion, Jira, Atlassian and the whole suite of Google and Microsoft.
Wanted to share what I have up until now though.
Deep Research, Canvas and Pro Search will come in later uploads.
Voice agents should also come afterwards, when they get somewhat better in tool calling and entonation and the like.

Hi HN,
I built DistApp, a tool for managing and distributing Android, iOS, and Desktop app builds. I created it after App Center Distribution was discontinued, I wanted a way to easily share builds with the QA team and users with different groups.
DistApp lets you manage multiple apps across different organizations and groups. It also supports self-hosting on your own infrastructure and is open-source https://github.com/yunusefendi52/distapp
You can try the free version by signing in with your Google account. I chose not to support email/password accounts to reduce abuse on the free version. But I’m open to suggestions if you think there’s a better way :)
Thank you
