Deepfakes are now undetectable. Proof is the new trust.

If it's not signed,
it didn't happen.

Stamp any media with cryptographic proof that it's real, unedited, and timestamped — before AI makes trust impossible.

The trust crisis is now your problem

Every photo, video, and document will be questioned. "Is this AI?" is the new default assumption.

Without proof
  • × Anyone can claim your media is fake
  • × No way to prove when it was created
  • × Evidence lost when servers go down
  • × Metadata is trivially spoofed
