Mod

Use Claude to transform any web page

Mod is a browser extension that uses Claude to transform any web page from a plain-language instruction. Say "hide the ads and highlight the key points" and an agent loop explores the page structure with tool calls, picks the right selectors, and rewrites the live DOM — hiding, highlighting, dimming, or annotating elements. Every change is reversible through an undo stack, and useful transforms can be saved to auto-apply on matching URLs. Built as a Manifest V3 extension that calls the Claude API directly, with no backend.
