Collaborative workspace for hand-drawn diagrams
ExcaliClaw is a browser-based collaborative workspace for creating, organizing, and sharing hand-drawn diagrams. It is designed for solo creators and teams that need persistent diagram storage alongside real-time editing and sharing.
The workspace combines automatically saved drawings, collections, cross-collection search, and JSON import/export with MCP tools for AI-assisted diagram creation. Users can work without installing software, collaborate through shared links, and connect diagram workflows with Claude, Cursor, or VS Code.
Features
Collections and search
Place drawings in folders and search across collections to locate diagrams quickly.
Real-time collaboration
Share a link, draw with other people in real time, and see collaborators’ live cursors.
Flexible sharing
Give others access through a public link or a username-based share.
Import and export
Export drawings to JSON and import diagrams from other tools, including Miro.
MCP tools for AI agents
Use MCP tools to let AI agents such as Claude, Cursor, and VS Code create diagrams with you.
Use cases
Engineering team collaboration
Create and maintain flowcharts, architecture sketches, and other shared diagrams while teammates review changes through live cursors.
Personal diagram organization
Keep multiple diagrams in folders, then use search to retrieve a specific board when working across projects or topics.
AI-assisted diagramming
Work with Claude, Cursor, or VS Code through MCP tools to generate or modify diagrams as part of an AI-assisted development workflow.
Sharing diagrams externally
Publish a diagram for clients, teammates, or other viewers using a public link or username-based sharing instead of sending files manually.
Diagram migration and backup
Move diagrams between ExcaliClaw and other diagram tools by importing supported drawings and exporting workspace data as JSON.
