Sign what you publish. Mark what your AI creates.
Every piece of content has a story. Encypher stitches it into your text, images, video, audio and documents. A hidden label shows who signed it, what they said about AI use, and whether it has changed.


Your work travels. Your name doesn't.
Articles, photos, and video are copied and reposted every day, and the creator's name rarely goes with them.

Text carries more than meets the eye.
A thumbs-up emoji looks like one symbol. Underneath, it is two characters: one for the hand and one for the skin tone.

We put a signed label inside the text.
Encypher writes it into characters that never show on screen. Readers see the same words; software can read the label.

Files carry one too.
Photos, video, audio, and documents hold the label inside the file, using the open C2PAC2PA: The Coalition for Content Provenance and Authenticity: the group that publishes the open standard for content labels. standard.

The label names the source.
It shows who signed the work, when, and whether they declared AI use.

Change one word, and the seal breaks.
Any edit made after signing shows up when the work is checked.
