Give every output a record anyone can check.

One vendor. One integration. Every output type. Mark signs text, images, audio, video, and documents such as PDF and Word under one output policy. Anyone can check them, free.

The technical marking, detection, and evidence layer for Article 50Article 50: The EU AI Act rule that AI-made content be marked in a form software can read, and deepfakes disclosed.. Your team and counsel still own legal scope and disclosure.

Use one output policy across text and media.

Start with what your team sends.

Text, images, audio, video, documents and fonts can all carry a label: in text it rides in the characters, in every other format it sits inside the file.
Text carries the label in its characters. Images, audio, video, documents and fonts carry it inside the file.

Mark once. Check every supported signal.

Use the dashboard, the APIAPI: Application programming interface: a way for one program to ask another to do a job, such as sign a file., or your current tools.

Send a file to the signing API, get it back signed with the label inside, and anyone can check it for free without an Encypher account.
Signing is one API call. Checking is free and needs no account.
  1. Choose the final output

    Pick the point after the model is done and before a person or system gets the result.

  2. Apply one marking policy

    Mark returns the text or file, its id, and the signed record your system keeps.

  3. Give everyone one check path

    Encypher Verify checks C2PAC2PA: The Coalition for Content Provenance and Authenticity: the group that publishes the open standard for content labels. and supported marks. Each type of proof stays separate.

Give every reviewer a clear answer.

The free check answers three questions: who signed, what they declared, and whether it changed.

  • Free AI output is signed under the Encypher name. To sign under your company name, choose an eligible plan and pass the identity check.
  • The result does not prove who owns or wrote the work. It does not prove the work is true or approved.

Create. Mark. Endure.

Mark one file free, check it, then use the same policy in production.
