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?
