napkin
Browser-based visual whiteboard for sketching ideas and collaborating with Copilot through drawings and sticky notes.
- Opens an interactive canvas on the user's desktop where they can draw, sketch, and add sticky notes, then share back to Copilot via a "Share with Copilot" button
- Reads whiteboard content through PNG snapshots (visual interpretation of sketches, diagrams, and layout) and optional JSON clipboard data (precise text from sticky notes and labels)
- Designed for non-technical audiences like lawyers, PMs, and business stakeholders with warm, jargon-free interaction
- Interprets visual sketches conversationally, describing what the agent sees and asking clarifying questions about groupings, workflows, and emphasis
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.
