Even with the rapid development of AI today, there is no software that can automatically generate swimlane diagrams.

If you need to automatically generate complex swimlane diagrams through code or data, you can consider using tools such as PlantUML or Mermaid.js.

If you just need to automatically generate some simple swimlane diagrams, I can recommend you an alternative software: ProcessOn.

ProcessOn is an online drawing software that can be used to draw swimlane diagrams. It has built-in graphic elements such as swimlanes and pools. You can create swimlane diagrams by simply dragging and dropping.

The most important point is that ProcessOn provides a large number of swimlane diagram templates, which you can directly clone and use for free, and then make appropriate modifications. In this way, a swimlane diagram is drawn, which is basically the same as automatically generated.
