About the startup

Free, open-source web annotation tool. Draw, highlight, and pin threaded comments on any live webpage, then share one link for real-time collaboration (live cursors, voice/video). New since launch: an element inspector for AI-ready handoff, a measure tool, and an MCP server so agents like Claude Code can resolve your annotations as a work queue. No accounts, ever.
