FAQ

Do files stay private?

Yes. A file is only visible to the account that uploaded it and is never used to train a model. The uploaded file is deleted as soon as processing no longer needs it — usually within hours; results stay on the account for 30 days, then are deleted too.

Do I need an account?

Yes — passwordless magic-link sign-in. 25 free credits on sign-up.

How do credits work?

One wallet across every tool, no subscription. Each job shows its cost before it runs.

Which formats?

WAV, MP3 and M4A for audio; MP4 and common formats for the video tools.
