FAQ

What should I paste into the input?

Any requirements text works, but one feature/goal per line gives the cleanest results (bullets are ideal).

Can it parse user stories like “As a… I want to…”?

Yes. It extracts the “I want to …” action and uses that as the use case title.

Does this create UML diagrams?

No. It generates use case text/specs (actors, flows, pre/postconditions) that you can later diagram if needed.

How do I include alternate or exception flows?

Enable “Include alternate/exception flows” or add Alt: on in the input header.

Is the output good enough for an SRS/PRD?

It’s a strong draft. You should still validate business rules, edge cases, and terminology with stakeholders.

Can I export to Markdown?

Yes. Choose “Markdown” in Output format to paste directly into README, wiki, or docs tools.

Is my data sent to a server?

No. Generation runs in your browser; the tool JavaScript does not make network requests.
