Devplan – Generate specs and coding prompts with deep context
Hi, I’m Chris and my partners and I are building Devplan, an AI product development tool that helps teams go from idea to working code faster. What Devplan does: - Creates deep contextual understanding from Github and the web with our open source context engine: https://github.com/devplaninc/contextify - Generates right-sized PRDs, user stories, and tech design based on company context - Gives a ballpark effort and complexity estimate for every user story - Breaks down requirements into structured coding prompts for tools like Claude Code, Cursor, Windsurf, or JetBrains…

Hi, I’m Chris and my partners and I are building Devplan, an AI product development tool that helps teams go from idea to working code faster. What Devplan does: - Creates deep contextual understanding from Github and the web with our open source context engine: https://github.com/devplaninc/contextify - Generates right-sized PRDs, user stories, and tech design based on company context - Gives a ballpark effort and complexity estimate for every user story - Breaks down requirements into structured coding prompts for tools like Claude Code, Cursor, Windsurf, or JetBrains Junie - Integrates with Linear and Jira to push generated project docs and tickets to your tracking system - Lets you kick off projects with images to refine specs with mocks, diagrams, or screenshots - Exports detailed coding prompts as standalone files or use our CLI to work with them directly Why we built it: We believe the next generation of product development will be built with AI at its core. But we’ve seen first-hand how the current tools fall short: - Docs from ChatGPT or Claude are useful but too general and lack context for real workflows - AI coding agents lose context quickly in large repos and generated code often requires re-work - Most approaches to planning for AI coding takes too long and isn't shared or reviewed, which slows teams down AI should remove that friction, not create more of it. We built Devplan to make planning and execution one connected flow. It starts with outcomes, adapts to the size of your project, and produces structured inputs for the coding tools you already use. Instead of bouncing between AI assistants, PM docs, and code editors, Devplan ties it all together so you can move faster without losing context. We have an MVP template for side projects, but the platform is being built for real teams who want to ship product with confidence while staying lean. We are still early and we’re iterating quickly. Would love to hear feedback from other builders. What’s working for you when it comes to planning and building with AI? P.S. If you want to try it, public beta is open: https://www.devplan.com

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.

Hey HN, Henry from Cactus here! We previously released Cactus Needle, a 14MB agentic LLM for tool call, device use, and structured extraction for phones, wearables, smart homes, small robots and microcontrollers. We got really great feedback here, and have now incorporated the suggestions to release Needle 2. The whole model is a single 14MB binary that runs a full session in 28MB of RAM; 45m parameters at 2bit compression. Needle hits 500 tokens/sec decode speed on a Raspberry Pi 5, sits between 400-1,500 tokens/sec on VR devices like Meta Quest 3S and Apple Vision Pro, and ranges…

I built the world's most impractical 1000-pixel display and anyone in the world can draw on it. It draws a single pixel at a time and takes 30-60 minutes to complete a single image. Anyone can participate in the project by voting for the next image to be drawn, and submitting images. https://kilopx.com/

Kitten TTS is an open-source series of tiny and expressive text-to-speech models for on-device applications. We are excited to launch a preview of our smallest model, which is less than 25 MB. This model has 15M parameters. This release supports English text-to-speech applications in eight voices: four male and four female. The model is quantized to int8 + fp16, and it uses onnx for runtime. The model is designed to run literally anywhere eg. raspberry pi, low-end smartphones, wearables, browsers etc. No GPU required! We're releasing this to give early users a sense of the latency and voices…

I was wondering how I can arrange objects along a spherical helix path, and read some articles on it. I ended up learning about parametric equations again, and make this visualization to document what I learned: https://visualrambling.space/moving-objects-in-3d/ feel free to visit and let me know what you think!

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. Source code and additional information is available on GitHub: https://github.com/dnlzro/horizon [1] https://html.energy/html-day/2025/index.html
