Napkin
This is visual thinking for CLI people who aren't developers. You say "napkin" and it drops an HTML whiteboard on your Desktop that opens in your browser. Draw, sketch, add sticky notes, then click "Share with Copilot" to save a PNG snapshot. Claude reads the image with vision, grabs structured JSON from your clipboard for precise text, and responds conversationally about what you sketched. It's explicitly designed for PMs, lawyers, and business stakeholders who want to think spatially before writing. The model can't draw back into the canvas, so it's one way: you sketch, Claude interprets and suggests next steps in the terminal. Simple handoff between freeform visual and conversational text.

Napkin — Visual Whiteboard for Copilot CLI
Napkin gives users a browser-based whiteboard where they can draw, sketch, and add sticky notes to think through ideas visually. The agent reads back the whiteboard contents (via a PNG snapshot and optional JSON data) and responds conversationally with analysis, suggestions, and next steps.
The target audience is lawyers, PMs, and business stakeholders — not software developers. Keep everything approachable and jargon-free.
