How it works

Describe your system

Name the key classes, their attributes and methods, and how they relate — inheritance, composition, association. Plain language or code-style descriptions both work.

AI builds the diagram

MyMap generates a UML class diagram with properly formatted class boxes, relationship arrows, and cardinality labels.

Edit and document

Add new classes, adjust relationships, or ask AI to add interface abstractions. Export as PNG or PDF for architecture docs and code reviews.

الأسئلة الشائعة

Is the class diagram maker free?

Yes — free to use without signing up. Free accounts include a generous number of AI messages per month. Upgrade to Pro for unlimited diagrams.

Does this follow UML class diagram standards?

Yes. The output uses standard UML notation — class boxes with name/attributes/methods sections, solid arrows for inheritance, dashed arrows for dependencies, diamonds for composition and aggregation.

Can I use this for database design too?

For database schema design with tables, foreign keys, and constraints, the ER diagram maker is a better fit. Class diagrams are designed for object-oriented software modeling.
