What programming languages are supported?

UML class diagrams are language-agnostic and can represent Java, Python, C#, TypeScript, C++, PHP, and any object-oriented codebase.

Can I show abstract classes and interfaces?

Yes. Mention which classes are abstract or interfaces, and AI will apply correct UML notation.

Is this useful for database or ORM design?

Yes. Class diagrams can model entities, relationships, and data structures before implementation.
