ChatUML
ChatUML is an AI-assisted diagram generator that simplifies the creation of complex diagrams by utilizing cutting-edge AI algorithms to produce clear and concise visuals. As such, it provides an effortless way to transform your idea to diagrams in no time.
Instead of doing the “math stuff,” the tool — powered by OpenAI’s GPT-4 — lets you chat and create diagrams.
ChatUML supports various diagram types, including Sequence, Use case, Class, Object, Activity, Component, Deployment, State, Timing, BNF, Gantt, Mindmap, Work Break Down, and Entity Relationship.
Once created, you will be able to access your diagram from anywhere, whenever you need them.
ChatUML can be tried for free, but it is very limited — offering just 5 credits. In order to do more with it, you will have to pay for more credits. AI computing is not cheap, so it makes sense…
