Usermods is an open-source browser extension that lets you customize any website by chatting with the LLM of your choice. It inspects the page, writes a userscript, tests it live and hands it to you with Try and Save buttons, and saved mods run on every matching page load.
Be the first to rate Usermods. Your feedback helps other users decide.
Open the side panel on any page, describe what you want changed, and the model reads a pruned DOM, computed styles and screenshots before proposing anything.
Saved mods run automatically on every matching page load and export as standard .user.js files.
Install mods from Greasy Fork or migrate your whole Tampermonkey library in one file.
