Visual whiteboard collaboration for Copilot CLI. Creates an interactive whiteboard that opens in your browser — draw, sketch, add sticky notes, then share everything back with Copilot. Copilot sees your drawings and text, and responds with analysis, suggestions, and ideas.
Napkin is a visual whiteboard collaboration skill that brings interactive diagramming and sketching capabilities directly into your Copilot CLI workflow. It opens a browser-based canvas where you can draw freehand sketches, create diagrams, add sticky notes, and arrange ideas spatially—then share everything back with Copilot for analysis and feedback. The skill bridges the gap between visual thinking and conversational AI, letting you think through complex problems with pen-and-paper flexibility while getting intelligent responses from your AI assistant.
The whiteboard supports freehand drawing, text annotations, sticky notes with different colors, and spatial layouts that help visualize relationships between ideas. When you're ready, clicking the 'Share with Copilot' button captures both a PNG snapshot of your canvas and structured JSON data containing text content and positions. Copilot reads the visual elements—sketches, arrows, groupings, emphasis marks—alongside the precise text from sticky notes to understand your thinking holistically.
Designed specifically for non-technical users like lawyers, product managers, and business stakeholders, Napkin keeps the experience approachable and jargon-free. Whether you're mapping out a project plan, brainstorming solutions, sketching workflows, or organizing research findings, this skill lets you leverage visual thinking without leaving your command-line environment. It's particularly valuable for exploratory work where spatial arrangement and visual annotation add clarity that text alone cannot provide.
Simply say 'let's napkin,' 'open a napkin,' or 'start a whiteboard' to Copilot. The skill will copy a whiteboard template to your Desktop and open it in your default browser automatically.
If ~/Desktop/napkin.html already exists, Copilot will ask whether you want to open the existing whiteboard or start fresh before overwriting it.
When you click the 'Share with Copilot' button on the whiteboard, it saves a PNG snapshot to your Downloads folder and copies structured JSON data to your clipboard. Copilot reads both to understand your drawings, sketches, and text annotations.
Napkin works on macOS, Linux, and Windows. The skill automatically uses the appropriate commands to open the whiteboard in your default browser based on your operating system.
No, Napkin is designed for non-technical users including lawyers, product managers, and business stakeholders. The interface and instructions are kept simple and jargon-free.
