The technical marking, detection, and evidence layer for Article 50. Your team and counsel still own legal scope and disclosure.

Signed result
Example resultThe signed result shows who signed the content, what they declared, and whether the file still matches. It does not prove who owns the work. It does not prove the work is true.

One verification layer
Customers and reviewers use one public path for text, images, audio, video, and files. Each type of proof stays clear.
Check C2PA proof and supported marks in one place. Recovery runs only when the right mark and resolver are present.
See the verification layerPaste signed text or upload a supported file. No account or API key is needed for a basic public check.
Verify an outputThe WordPress plugin can show readers a badge and public check link on each signed post.
See WordPress signingHow it works
Use the dashboard, API, proxy, or a tool your team has now.
Pick the point after the model is done and before a person or system gets the result.
Mark returns the text or file, its id, and the signed record your system keeps.
Encypher Verify checks C2PA and supported marks. Each type of proof stays separate.
Proof details
A free public check shows who signed the file, what they said about it, and if the signed content still matches. Reviewers get the answer without opening a ticket.
