Diagramming AI

As an AI diagram generator, Diagramming AI differs from most by letting you choose which language model draws the diagram.

Diagramming AI creates, edits and discusses UML diagrams and workflows from text prompts, and every plan includes all editors.

The model list grows as you pay more.

The free plan gives you 2 projects, 3 diagrams per project, 10 credits and 3000 input characters, with GPT-4.1-mini, Gemini-2.0-Flash and Claude-3.5-Haiku.

That is enough to test it, not to work in.

Lite costs $3 a month and adds unlimited projects and diagrams, 250 credits, URL to Diagram and Image to Diagram, which turn a web page or a picture into a diagram.

Starter at $6 a month raises the limits to 800 credits and 12000 input characters and opens up GPT-4.1, Gemini-2.5-Pro and Claude-3.7-Sonnet.

Pro at $14 a month keeps those models and goes to 2,500 credits and 20000 input characters.

Credits are the real cap, so heavy users will land on Pro.
