FAQ

TypeGen — paste sample JSON or CSV and get TypeScript interfaces, type aliases, or a Zod schema with assumption notes.

What does TypeGen do?

You paste sample data and choose an output style. TypeGen infers types, explains assumptions (nullable fields, unions, optional keys), and flags ambiguous shapes you should double-check before shipping.

Is this a substitute for code review?

No. TypeGen is decision-support for developers. It is not legal advice, not a compiler, and not a certification that your production types are correct.

Do you guarantee 100% correct types?

No. Sample data can under-represent production shapes. TypeGen does not guarantee 100% correctness or that you will never miss an ambiguous field. Always review before merging.

What standards do you reference?

We align with common TypeScript handbook practices and Zod schema patterns as industry guidance — not as a formal certification seal. Outputs remain decision-support for your team.

What happens if AI is unavailable?

Fail-closed: explicit Demo mode is labeled; missing configuration returns 503; upstream failures return 502; quota returns 429. Never silent mock as live AI.

How does pricing work?

$19/month or $190/year via /api/checkout with monthly or yearly cycle. Enterprise can include BYOK/DPA. Annual UI shows monthly-equivalent price plus savings.
