Describe a diagram in a sentence and the AI draws it on a real draw.io canvas. Edit it by hand like any draw.io file, or select a few shapes and tell the AI what to change. Every AI change is a version you can compare, restore or undo, and the result exports as .drawio, .png or .svg.

Available as a web app, a desktop app for Windows, macOS and Linux, and an MCP server for AI agents such as Claude Code, Cursor and VS Code.

Highlights

Draw

• Architecture diagrams, flowcharts, sequence diagrams and more from one sentence, with built-in AWS, Azure, GCP and Kubernetes icon libraries
• Connectors can carry a flowing animation
• Upload a screenshot or a sketch and the AI redraws it; upload PDF, Markdown, code and other text files and get a diagram of their content

Edit

• Edit by chat: changes stream onto the canvas and the shapes the AI just changed are highlighted
• Ask about a selection: select shapes on the canvas and the AI changes only those
• Versions and undo: every AI change is a version card with a thumbnail; compare it with the canvas, restore it or undo it, and Ctrl+Z on the canvas also takes back an AI change in one step
• It is a normal draw.io diagram: double-click to rename, drag, restyle, use several pages, and export as .drawio, .png, .svg or .drawio.svg at any time

Use

• 25 model providers, including an OpenAI-compatible preset for any other URL; enter your own API key in the browser and it stays on your machine
• Models that reason show their thinking
• Dark mode; the interface is available in English, Simplified Chinese, Traditional Chinese and Japanese

Examples

More examples, each with its prompt and model, are in the gallery.

Use it

Online demo

Open next-ai-drawio.jiang.jp, nothing to install. The demo has a usage limit; click the settings icon in the chat panel and enter your own provider and API key to lift it. The key stays in your browser and is never sent to the server for storage.

Desktop app

Download the Windows, macOS or Linux installer from the Releases page.

In your AI agent (MCP)

https://github.com/user-attachments/assets/6f53a67b-ab21-4113-9fee-7fb32f9de678

Through MCP (Model Context Protocol, the protocol AI agents use to call outside tools), Claude Desktop, Cursor, VS Code and others can draw draw.io diagrams directly. Add this to your client's MCP configuration:

{
  "mcpServers": {
    "drawio": {
      "command": "npx",
      "args": ["@next-ai-drawio/mcp-server@latest"]
    }
  }
}

In VS Code or Cursor, one click adds it:

For Claude Code, one command does it (--scope user makes it available in every project):

claude mcp add --scope user drawio -- npx @next-ai-drawio/mcp-server@latest

It is also a plugin in the Claude Code community marketplace (Claude Code 2.1.275 or later):

/plugin install next-ai-drawio --marketplace anthropics/claude-plugins-community

Then ask the AI for "a flowchart of user authentication with login, MFA and session management" and the diagram appears in your browser as it is drawn. The MCP server has most of the web app's drawing features:

• The same drawing rules, icon libraries (AWS, Azure, GCP, Kubernetes and more) and canvas as the web app: the AI's changes are outlined, one Ctrl+Z takes them back, and the AI reads the shapes you select
• A screenshot tool, so the AI looks at the rendered diagram and fixes it
• Version history, several pages, export as .drawio, .png, .svg or .drawio.svg, and auto-save to ~/.next-ai-drawio/; the draw.io editor ships inside the package, so the preview works offline

The MCP server page has the setup for Codex, VS Code, Cursor and other clients, every tool, and how it compares with other draw.io MCP servers.

Compared with draw.io's built-in AI

draw.io has its own Generate tool (Arrange > Insert > Generate). It runs inside draw.io on a free hosted model or your own API key, and it can change a diagram, page or selection that you attach to its chat. Next AI Draw.io sends the current canvas, including your hand edits, with every message, turns every AI change into a version you can compare or restore, and works with 25 providers, including local models through Ollama, on the demo site, in the desktop app or on your own server.
