What is free

Free comes in three shapes

Every signed document strengthens the coalition. Signing is free. We charge for the tools that act on the record: evidence, analytics, notice, and identity.

Every tier signs through Encypher's claim-signing Certificate Authority and Time Stamp Authority on the official C2PA Trust Lists. Encypher's generator product is listed as C2PA conformant at assurance Level 1.

Free Publisher

Unlimited signing for normal publishing, plus publisher attribution and public verification, once your publisher identity is proven.

Sign as much normal published work as you like, within fair-use limits
WordPress plugin that signs on publish and shows readers a badge
A free public check for anyone, by page or by API, with no login
Invisible signatures that survive copy-paste and redistribution
Join the coalition and earn when partners license your work. Most of every deal goes to you, on the terms in your agreement

Signing your own published work stays free. Your verified publisher name, backed by your domain, appears once we accept your proof.

Enterprise and compliance content is never indexed for coalition licensing; coalition enrollment is opt-in for publishers. Learn how the Coalition works. On WordPress? Install the plugin (20 minutes).

Mark pricing

Choose the result you need Mark to deliver

Published work and official content are free. AI output is priced by volume.

The content declaration and operating model decide the price. File format does not.

Declared AI output

An item your team labels as AI generated and submits to Mark. The trial covers 1,000 items a month; paid plans raise that limit.

Original human and official content

We do not charge ordinary signing by the document. Paid plans add your organization name once we accept your proof. They also add signing-time records, team seats, and production controls. Bulk archive work and unusual setups are priced apart from this.
