Pinpoint

Pinpoint is a free, open-source Chrome extension for giving UI feedback to AI coding agents. Turn it on, click any element (or select text) and write what should change. Pinpoint captures the selector, the React/Vue/Svelte component tree and the exact source file and line, then copies it all as clean markdown for Claude Code, Codex or Cursor. Works on any site and stack. Notes stay in your browser: no account, no tracking.
