Questions
that matter.

Straight answers to the questions we hear most.

Is ProvSeal enough to comply with the AI Act?

ProvSeal provides the technical means to mark your outputs with C2PA. Your exact obligations depend on your role: have them confirmed by your legal counsel.

Which models are compatible?

C2PA does not depend on the model. What matters is that the output format can carry Content Credentials.

Does signing make files heavier?

The manifest adds metadata. The impact depends on the format, the manifest contents and the certificate chain.
