Content provenance platform
Articles, photos, podcasts, video, websites, ads, live streams. Sign each one so anyone can check who published it and that nothing changed. Built on the C2PA standard we co-authored. Free for every publisher.
40+
media formats signed and verified, from text to live streams

The products
Every product runs on the same signing and verification engine. Content you sign with one counts for all of them.
The stack
Built on C2PA with proprietary watermarking across 40+ media formats.
Signing
C2PA manifests for articles, images, audio, video, PDFs, fonts, and live streams
Watermarking
Audio, video, and image watermarks plus invisible text embeddings
Verification
Free public API, tamper detection, quote integrity, watermark extraction
Evidence and audit
Attribution analytics, exportable evidence packages for counsel, tamper-evident audit logs
Rights
Per-segment licensing, rights resolution API, publisher profiles
Distribution
WordPress, Prebid ad-tech, CDN edge, REST API, CLI, browser extension
Capabilities
Six capabilities, one engine, every content format you produce.
Built on the C2PA open standard
Encypher authored the C2PA standard for unstructured text and co-chairs the Text Provenance Task Force alongside these member organizations. Logos indicate C2PA membership.
The missing layer
Content provenance is not a replacement for access control or attribution tools. It is the layer that makes them enforceable. Mark writes the record those layers rely on, and Meter reports what the record shows.
Layer 1
Tell AI crawlers not to scrape. These tools work at the server level, but only when AI companies respect your directives.
When crawlers ignore these signals, content-level provenance provides the evidence that your terms were attached and violated.
Layer 2
Proof of origin embedded in the content itself. Articles, photos, audio, video, websites. Mark binds the publisher, the organization identity behind it, and the licensing terms to each output, and that binding travels with every copy. Trace embeds a recipient-specific identifier in each distributed copy, Seal binds an integrity record so a recipient can detect changes made after signing, and Meter turns that provenance activity into bounded usage reports. This is the layer Encypher owns, and every product lives in it. Meter is an early partner program.
Layer 3
Marketplaces estimate which sources shaped an AI output and route revenue to publishers, inside opted-in ecosystems. Encypher sits under that work rather than beside it: Mark supplies the signed per-output record and machine-readable terms an attribution estimate can be checked against, and Meter turns provenance activity into bounded usage reports for licensing and rights review. Encypher does not price content, broker deals, or move money.
Signed origin makes an attribution claim checkable instead of a statistical estimate. Meter is an early partner program, and every report keeps observed provenance activity separate from partner-supplied retrieval and usage events.
