Kichan.ai, Chrome extension generates JavaScript to augment any website
Hey HN! I've been working on https://kichan.ai, a Chrome extension that lets you modify any website using prompts. It uses Google Gemini to generate JavaScript that runs directly on your browser web page. How it works: Click the extension to open a side panel. Type what you want to do like "Remove all ads", "Add a share button", or "Make this table sortable". KICHAN generates JavaScript using Gemini 2.5 Flash and executes it immediately. Your custom scripts are saved and can run automatically on specific websites. Key features include context-aware generation where you can…

In the maker’s words, at launch
Hey HN! I've been working on https://kichan.ai, a Chrome extension that lets you modify any website using prompts. It uses Google Gemini to generate JavaScript that runs directly on your browser web page. How it works: Click the extension to open a side panel. Type what you want to do like "Remove all ads", "Add a share button", or "Make this table sortable". KICHAN generates JavaScript using Gemini 2.5 Flash and executes it immediately. Your custom scripts are saved and can run automatically on specific websites. Key features include context-aware generation where you can right-click any element to add it to a "context buffer" that helps the AI understand exactly what you want to modify. Scripts can also run automatically on matching URLs using glob patterns. Example use cases I've found useful include automating repetitive tasks like auto-reloading my GitHub PR page and beeping if there's something new, removing distracting elements from news sites, adding keyboard shortcuts to web apps, getting banned from browser games for scripting too much (twice), and customizing form behavior. The goal is to give users programmatic control over their web experience without needing to code. If you can describe it, KICHAN tries to build it. Caveats: Very beta! CSP/iframe/canvas heavy sites most often block injection. I am not a JavaScript or web developer so it is heavily vibecoded. Expect surprises. Would love feedback and especially: What would you use this for? --- Website: https://kichan.ai Extension: https://chromewebstore.google.com/detail/kichan-ai-web-augme...

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…

Hey HN! Pilots everywhere are required to keep a logbook of all their flying hours, aircraft, airports, and so on. Since I track everything digitally (some people still just use paper logbooks!), I put together some data visualizations and a few 3D globes to show my flying history. This globe is probably my favourite so far: https://jameshard.ing/pilot/globes/all If you’ve got ideas for other graphs or ways to show this kind of data, I’d love to hear them!

I was the main contributor to workout.lol, an open-source fitness app to easily build a workout routine. The project had traction (1.4k GitHub stars, 95 forks, ~20K visits/month), but was eventually sold due to video licensing hurdles. The new owner stopped maintaining it, and the repo went abandoned. Over the next 9 months, I sent 15 emails to try to save it : no replies. Feature requests & issues were ignored. The community was left with a "broken" tool let's say. I couldn't just let it die So I built the new version from scratch with the same open-source spirit, but a better…
