Questions

When can I buy a plan?

Paid plans open after the beta, planned for December 2026. Pick a plan now and we'll hold it for you; beta design partners get in first.

Is this legal advice?

No. The kit supports your compliance work with Article 50, but it can't guarantee compliance. For your specific situation, talk to a lawyer.

What counts as a marked asset?

Each generated image, audio or video file signed with a C2PA manifest, and each text response tagged as AI-generated, through the marking API.

What if I go over my limit?

Nothing breaks. Extra marked assets are billed per 1,000 on top of your plan.

Do you store my users' conversations?

No. The evidence log keeps hashes and metadata about what was shown or marked, never the content of chats or generated files.

Where is my data hosted?

In the EU, on servers in Germany.
