Show HN: ToDiagram AI – From text to diagram, fast and easy

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.
