How it works

Describe the states and transitions

Name the possible states your system or entity can be in, and describe what triggers movement between them. Works for software systems, UI flows, business objects, or physical processes.

AI builds the diagram

MyMap generates a state diagram with rounded rectangles for states, arrows for transitions, and labels for triggers and conditions — with start and end states clearly marked.

Edit and document

Add new states, change transitions, or ask AI to identify edge cases and error states. Export as PNG or PDF for system documentation and code reviews.

الأسئلة الشائعة

Is the state 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.

What systems are state diagrams good for?

Order management, user sessions, document approval workflows, payment processing, IoT device states, game mechanics, UI navigation flows, or any system where an entity moves through defined states.

Does this follow UML state diagram notation?

Yes. The output uses standard UML notation — rounded state boxes, labeled transition arrows, filled circle for the initial state, and circled dot for final states.
