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…

What it does
KICHAN is a free Chrome extension that turns requests into instant JavaScript page tweaks. Personalize and automate any website in seconds.
Type what you want—"remove pop-ups", "highlight email addresses", "add a Download button"—and KICHAN turns it into a tiny userscript, runs it, and saves it for next time. Generated scripts are saved automatically. Manage your library: rename, enable/disable, and set scripts to run on specific websites, creating your own web toolkit. Automate repetitive tasks, extract information quickly, and remove distractions to focus on what matters. If you can describe it, KICHAN can try to build it. Empowering everyone to customize their web experience, without writing a line of code. Through a simple popup or right-click, tell KICHAN what you want to do on the current page (e.g., "Add a button…from kichan.ai

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…
