What it does

In the maker’s words, at launch

I originally built this because I wanted a way to practice answering questions I get often when talking to potential users. I got carried away and built a full multiplayer text editor with AI review... Here are all the features: - Use templates like the YC App questions. - Create pages for your pitch to investors, customers, or friends and family. - AI Review with customizable prompts - Practice mode (Mobile Friendly): answer questions verbally, get transcriptions, and self-rate your performance - Share pages for real-time multiplayer editing - Authentication & User Management via Every App / Better Auth This was a cool project for working with Cloudflare's Durable Objects which support serverless websockets & multi player. It was pretty hard to get this working well, I see why Tip Tap has a SaaS for that lol

    R3 – A Local Code Review Tool for You and Your AI AgentJul 2026 · github.com · ▲5

    I built r3 to scratch my own itch when reviewing long design doc and planning doc from AI. The chat interface is inherently bad at tracking multiple pieces of feedback across different parts of a document, so I created a lightweight local web UI to organize the review process. I have been using it on my own projects for one week, and it has made giving structured feedback to AI much easier. I thought others working with AI coding agents might find it useful too. I'd love to hear what you think and any feedback you have!

  • 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…
