A rich, HTML-native document canvas for human <> AI collaboration
Another AI document editor when Notion, Coda, and Craft already solve this.
It wires Mermaid into the MCP ecosystem so an assistant can spit out diagram source and immediately open a live browser preview over WebSocket, with instant re-renders and SVG/PNG download.

Developers and engineers who use AI assistants (Claude, Cursor, etc.) and need to generate or iterate on diagrams quickly; technical writers and architects who want live diagram previews.
