MyMapDescribe the interaction
Name the systems, services, or actors and describe how they communicate. Include request/response pairs, conditions, or async calls if relevant.
Sequence Diagram Maker
Describe the actors and message flows in your system and AI builds a sequence diagram — lifelines, arrows, activation boxes, and labels, all in the right order.

How it works
AI builds the diagram
MyMap generates a sequence diagram with vertical lifelines, horizontal arrows for messages, and activation boxes — all in correct sequential order.
Edit and document
Add new actors, change message labels, or ask AI to add error paths and retry loops. Export as PNG or PDF for technical docs.
Built different
AI that doesn't just chat — it sees, creates, and streams on your canvas.
Context-aware AI
AI that sees your whole canvas
AI understands node positions, connections, and neighbors — not just raw text. Select a node and it knows what's nearby, what's linked, and how to build on it.

Frequently asked questions
- Is the sequence 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 support UML sequence diagram notation?
- Yes. The generated diagrams follow UML sequence diagram conventions — lifelines, synchronous and asynchronous arrows, activation bars, and notes. You can also use plain language and AI will apply the correct notation.
- What use cases are sequence diagrams good for?
- API design, microservice architecture, authentication flows, database query patterns, event-driven systems, and any scenario where you need to show the order of messages between components.
