Diagramming AI
FreemiumGenerate and edit Mermaid, PlantUML and Excalidraw diagrams by chat
What is Diagramming AI?
Diagramming AI turns plain English into editable diagrams in Mermaid, PlantUML, GraphViz, D2 or Excalidraw. You describe a system or paste notes, refine the result in chat and watch a live preview update. It suits developers and teams documenting systems.
The workflow has three steps: describe the diagram, refine it with chat suggestions and instant edits, then save versions and share a read-only public link. Projects are stored so you can come back to them.
A gallery of example diagrams and documentation are on the site. Excalidraw diagrams can be restyled with 48 color themes in one click, which changes the look without asking the AI to regenerate the layout.
