One Platform for
Everything You Publish
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.
Content Provenance Stack
Everything between hitting publish and getting paid. Built on C2PA with proprietary watermarking across 44 media formats.
Core Capabilities
Protect, verify, and monetize every content format you produce.
Sign Every Format You Publish
Articles, photos, podcasts, video, PDFs, websites, live streams. One API handles all of them. Composite signing bundles an entire article package into a single provenance unit, so the hero image, podcast clip, and written piece share one verifiable chain of custody.
Watermarks That Survive Everything
Invisible text embeddings survive copy-paste, scraping, and CMS rendering. Audio and video watermarks survive transcoding, compression, and format conversion. Image watermarks survive cropping and resizing. Together they are built for the EU AI Act marking requirements that start applying August 2, 2026.
Free Verification for Anyone
Any journalist, court, compliance team, or AI company can verify any signed asset at no cost through the public API. Quote integrity verification checks whether AI-generated citations match your original signed content.
From Detection to Licensing
Attribution analytics show where your content appears across the web. Formal notices put AI companies on documented notice. Evidence packages give your counsel a cryptographic chain of custody. The pipeline works across articles, images, audio, and video.
Rights at Every Level
Publisher rights profiles, licensing terms, and usage policies travel with content. Per-segment rights let you license one section of an article under Creative Commons while keeping another exclusive. AI companies resolve rights programmatically before ingestion.
Coalition Licensing
Auto-enrolled in the Encypher Coalition. Every format you sign is indexed for licensing deals. Publishers keep the majority of revenue on every deal.
We're Authoring the Future of Content Authenticity
Encypher co-chairs the C2PA Text Provenance Task Force and implements the standard across all media. Building content authenticity together.
Strengthens Your Existing Stack
Content provenance is not a replacement for access control or attribution tools. It is the layer that makes them enforceable.
Access Control
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.
Content Provenance
Proof of ownership embedded in the content itself. Articles, photos, audio, video, websites. Works whether AI companies cooperate or not.
Attribution & Monetization
Estimate which sources contributed to AI outputs and route revenue to publishers. These tools work inside opted-in ecosystems.
Cryptographic proof of origin makes attribution claims verifiable, not just statistical estimates.
