Excalidraw
Supports UIby excalidraw
Interactive MCP app that streams hand-drawn Excalidraw diagrams as SVG with smooth animations directly in chat.
What it does
Excalidraw MCP transforms the AI chat experience by rendering a fully interactive, hand-drawn virtual whiteboard. Instead of static images, it streams SVG diagrams that the AI can create and modify in real-time, providing a visual canvas for architecture diagrams, brainstorming, and sketching.
Key features
- Live Streaming: Renders diagrams as SVGs with smooth hand-drawn animations.
- Interactive Editing: Allows for fullscreen interactive editing of the generated diagrams.
- Camera Control: Features smooth viewport camera control for navigating large sketches.
- Direct AI Integration: Enables AI to "draw" complex concepts via simple natural language prompts.
