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.
