ChatUML

Describe your system in words, get a diagram you can edit

Natural language to diagram

Describe actors, steps and relationships in a sentence and receive a structured, editable diagram instead of drawing boxes by hand.

Broad diagram coverage

Supports the notations software teams actually use — UML class and use-case diagrams, sequence diagrams, flowcharts, BPMN process maps, C4 architecture views and mindmaps.

Text-based diagram source

Diagrams are stored as readable text notation, which makes them easy to diff, review and keep in version control alongside the code.

Iterative refinement

Keep chatting with the assistant to add participants, split flows or restyle the render without starting the diagram over.
