DrawIO editor with AI and MCP support
DrawIO2Go is a DrawIO editor that adds AI-assisted diagram creation, canvas context selection, and version management. It can run as a web app or as an Electron desktop app, and it exposes an MCP service for connecting canvas content to other applications.
Builders who want to edit diagrams with an agent and share canvas context with other tools.
You can build and revise diagrams with AI help instead of switching between a diagram editor and your agent.
What it does
AI-powered diagram editing
Lets you generate and modify DrawIO diagrams with LLM assistance, including style and knowledge settings.
Canvas context capture
Can pass selected canvas elements into the conversation so the agent sees the part you mean.
Version management
Supports manual versions and AI-created versions, plus comparison and rollback between versions.
MCP service
Starts an MCP service for canvas content version management so other apps can connect to it.
Multi-page editing
Supports editing multiple DrawIO pages and limiting changes to the page you want.
Custom DrawIO canvas
Lets you change the default theme and point the editor at a self-hosted DrawIO URL.

NEW: Canvas EnhancementAfter inserting images, it will automatically check if connection lines overlap with elements, avoiding AI connection errors |
NEW: LLM EnhancementSpecify drawing style/colors and even add DrawIO element knowledge* |
NEW: Custom DrawIO CanvasFully customize DrawIO canvas, modify default appearance theme / switch to self-hosted URL |
Version ManagementManually create versions / AI automatically creates versions |
AI-Powered ModificationXPath-based precise deletion, modification, and query tool, effective and token-saving** |
MCP ServiceStart an MCP service with canvas content version management to connect with other applications |
Multi-Page EditingSupports multi-page drawio editing, let AI only edit the parts you want to modify |
Version ComparisonEasily compare / rollback differences between different modified versions |
Canvas ContextNo longer need to describe "the few xxx on the far right", simply drag-select with the mouse, the conversation will automatically parse canvas elements into context*** |
** Currently LLM API supports Openai/Deepseek/Anthropic/Gemini formats
*** Limited by Web API restrictions, mouse selection perception is not available on the web. But Web still has basic compressed canvas content context injection functionality
