How to make and share diagrams with Le Chat
How to make and share diagrams with Le ChatLe Chat (Mistral’s Le Chat) can draw architecture diagrams, flowcharts, and sequence diagrams, but on its own they end up as text in the chat or a file only you can open. Connect Diagram once and every diagram Le Chat makes becomes a link you can share, which stays current as the diagram changes.
1. Connect Diagram to Le Chat
In Le Chat: Connectors → + Add Connector → Custom MCP Connector. Name it Diagram, paste this URL, and click Connect:
https://diagram.la/mcp
Sign in once: Le Chat detects the sign-in and opens it: sign in with Google and click Allow.
2. Ask for a diagram
In a new chat, enable Diagram in the tools menu, then describe what you want in plain words. For example:
- “Draw a diagram of a typical OAuth login and give me a link.”
- “Turn this process into a flowchart I can send to my team.”
- “Make a sequence diagram of how a payment moves between the app, Stripe, and the bank.”
- “Draw our org chart from this list.”
Le Chat draws it and gives you a link.
3. Share the link
Paste it in Slack, a pull request, or a doc. Diagrams start private; add people to the project, share it with your team, or make one public. When it changes, ask Le Chat to update it: the link stays the same and every version is kept.
