Diagrams from text, code, or a single prompt
Write Mermaid syntax and watch the diagram build automatically, with clickable links between nodes and their code.
Describe a diagram, speak it, upload a document, or paste a transcript and let the assistant draft it while holding context across the conversation.
Co-edit diagrams live and share them with a single link that viewers can open without creating an account.
Render diagrams in your IDE, embed them in docs and wikis, and generate or validate them from Claude, VS Code, and Cursor through an MCP server.
The open-source diagramming studio for builders
Paste a public GitHub repository and OpenFlowKit reads its files in the browser to draw modules and connections, with every arrow cited to the source line it came from.
29 diagram tools for Claude Code, Codex, Cursor, VS Code, Windsurf or any MCP client, so an agent can draw on the diagram you have open, one undo away.
Write or paste Mermaid, D2 or Structurizr; the text and the canvas remain the same diagram, so you can round-trip between syntax and visuals.
Move from system context to containers to components in linked views that all stay grounded in a single architecture model.
