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.

Why you can trust it

Built on the open standard we co-authored

  1. 1

    Open standard

    Built on the C2PA standard for unstructured text, which Encypher authored; the text standard published January 8, 2026.

  2. 2

    Keyless verification

    Anyone can verify signed content for free, with no account and no API key.

  3. 3

    Travels with the text

    The mark is embedded invisibly and survives copy and paste, so proof goes wherever the content goes.
