How it works
Seal it

Drag and drop gives an instant authentic-or-altered verdict.
Seal and verify something right now
Paste your content
Sample article pre-filled. Edit it or paste your own.
Free to try
Paste your text and go. No account, no setup.
Invisible to readers
The mark is hidden inside the text. Anyone reading it sees exactly what you wrote, nothing different.
Anyone can check it
It uses an open standard Encypher helped create, so anyone can confirm where the text came from.
Where this fits
Security and data handling
Your keys, your control
Seals are signed with keys tied to your organization. Bring-your-own-key (BYOK) is available for teams that require key custody.
Verification needs no account and no trust in us
The seal is a C2PA manifest inside the file. Any standards-based verifier can check it independently.
Audit trail on every operation
Every seal and verification is logged and exportable for compliance reviews.
