Summary

ToDiagram AI is a general-purpose diagramming tool that converts text formats like JSON and YAML into diagrams quickly and easily. The latest updates include an MCP Server and ToDiagram Chat, allowing users to generate diagrams using natural language and their own locally stored OpenAI key without sign-up. This demonstrates ongoing progress in AI-powered visualization tools, making data representation more accessible and customizable.

I’ve been working on creating diagrams from JSON, YAML and similar formats for about three years. Over time it has grown into a general-purpose diagramming tool. With the recent addition of the MCP Server and ToDiagram Chat, I’m optimistic about where it’s headed. You can use your own OpenAI key, stored locally, without needing to sign up and generate diagrams by using natural language.
