Score: 6.3/10 (Innovation: 6, Technical: 5, Documentation: 7, Utility: 7)

EditUI is a browser extension that lets developers visually point at UI elements on a live page, leave notes about desired changes, and batch them into a single prompt for AI coding agents like Claude Code, Cursor, and Codex. It bridges visual context and AI agents without accounts, MCP, or repo setup, making frontend iteration more precise and efficient.

Target audience: frontend developers, full-stack developers, designers collaborating with developers
