Overview

Annotate any webpage and hand AI coding agents (Claude Code, Cursor, Codex) a structured prompt with cropped screenshots.

Point at what's wrong, and let your AI coding agent fix it. Agent Annotator lets you click elements or drag regions on any webpage, add a comment to each, and copy one structured prompt with cropped screenshots that Claude Code, Cursor, Codex, Antigravity or Windsurf can act on. • Activate with the toolbar icon or Alt+Shift+A. Nothing runs until you do. • Annotate several elements or regions in one pass, then press Cmd/Ctrl+Enter. • Detects React, Vue and Svelte components so the prompt names the component, not just the DOM node. • Captures the screen once and crops each annotation from it. • Optional local hub saves screenshots to disk and exposes them to agents through MCP. • All data stays on your computer. Nothing is sent to us or any third party.
