AI Sequence Diagram Generator

Sequence diagrams show how objects or components interact over time by depicting the messages exchanged between them in chronological order. They use vertical lifelines for participants and horizontal arrows for messages, making them ideal for documenting API interactions, authentication flows, and microservice communication. viz42 generates sequence diagrams with proper activation bars, return messages, and loop/alt fragments.

Common use cases

How viz42 helps

Frequently asked questions

Can I show loops and conditional logic?

Yes. Use keywords like 'repeat', 'loop', 'if/else', or 'optionally' in your prompt. viz42 will generate proper loop, alt, and opt combined fragments.

How do I differentiate sync and async calls?

Mention whether calls are synchronous (request/response) or asynchronous (fire-and-forget, queue). viz42 uses solid arrows for sync and dashed arrows for async messages.

Can I include database interactions?

Absolutely. Include database participants in your description and viz42 will show queries and results as messages on the database lifeline.
