# Encypher (Extended Reference) > Content provenance and rights infrastructure for the AI era. Encypher authored the C2PA standard for unstructured text, co-chairs the C2PA Text Provenance Task Force, and passed all four C2PA Conformance Program categories on June 30, 2026. Its products attach portable, verifiable provenance, organization identity, and machine-readable rights terms to content and AI outputs. Encypher reports provenance and licensing signals; it is not an enforcement mechanism. Last verified: July 27, 2026. This is the expanded companion to https://encypher.com/llms.txt. ## About Encypher Encypher provides content provenance and rights infrastructure for publishers, AI companies, and enterprises. Encypher authored the C2PA standard for unstructured text (published January 8, 2026 in the C2PA 2.3 specification) and co-chairs the C2PA Text Provenance Task Force alongside Google, BBC, OpenAI, Adobe, and Microsoft. In June 2026 Encypher passed the C2PA Conformance Program in all four categories: generator, validator, certificate authority, and time stamp authority. The product line is four tools in a fixed order, Mark, Meter, Trace, and Seal. Mark, Trace, and Seal are available now; Meter runs as an early partner program with no self-serve path. Everything is built on the open C2PA standard and on invisible text watermarking that survives copy-paste and redistribution. Founders: - Erik Svilich, Founder and CEO. Authored the C2PA standard for unstructured text and co-chairs the C2PA Text Provenance Task Force. Filed patent ENC0100 (83 claims, January 7, 2026) covering granular content attribution with Merkle tree authentication. - Matt Kaminsky, Chief Commercial Officer. 13+ years in digital media and ad-tech revenue leadership. ## The report-not-prevent boundary Encypher reports provenance and licensing signals. It does not gate, proxy, or intercept traffic, and it is not an enforcement mechanism. The rights engine returns a deterministic, machine-readable permit or prohibit verdict that a customer's own retrieval layer can act on. Rights terms carried on content are supplied evidence of the terms a publisher publishes, not proof of legal copyright ownership. Domain verification supports authority to publish terms, not legal ownership of the underlying work. ## Products Canonical order: Mark, Meter, Trace, Seal. - [Mark](https://encypher.com/products/mark): Available now. Attach portable C2PA provenance, organization identity, and verified rights terms to completed content and AI outputs. One Mark API covers text, images, audio, video, PDF, and Microsoft Office files. Start self-serve, then scale the same API across an enterprise application portfolio. Call Mark after generation completes, so the signature binds to the finished content object. - [Meter](https://encypher.com/products/meter): Early partner program. Turns per-answer RAG evidence into a bounded source-use report for rights and licensing review. Observed provenance activity (verification results, crawler sightings) stays separate from partner-supplied retrieval, grounding, and citation events, and unresolved gaps are labelled rather than inferred. - [Trace](https://encypher.com/products/trace): Available now. Give every recipient a copy with its own invisible fingerprint. When protected content leaks, a recoverable marker connects it to the recipient, session, and timestamp, and it survives a trip through a printer and scanner. It identifies the copy, not the person who moved it. - [Seal](https://encypher.com/products/seal): Available now. Bind an integrity record to a file so recipients can detect changes made after signing. Seal covers PDF, images, audio, video, and Microsoft Office formats. Anyone can verify a sealed file for free, with no Encypher account. ## Platform - [Platform overview](https://encypher.com/platform): One signing API for every format, watermarks built to survive distribution, and free public verification for anyone. Encypher logs third-party AI crawlers hitting your own site and API surfaces and turns observed activity into an evidence package with a cryptographic chain of custody. There is no web-wide crawl, no search-results monitoring, and no view inside an AI answer. Encypher sits at the content-provenance layer, beneath access control (robots.txt, TollBit) and above attribution and monetization tools. ## Pricing - [Pricing](https://encypher.com/pricing): Self-serve plans plus enterprise. Plan ladder (declared AI-output items per month): - Free: 1,000 AI-output items per month and 5 EU AI Act Article 50 compliance certificates per month. Unlimited signing for normal publishing use, with fair-use guardrails. Free public verification API, WordPress plugin, Python SDK, CLI, and browser extension. - Mark Starter: $99/mo or $990/yr. 10,000 AI-output items per month, unlimited Article 50 compliance certificates, 2 team seats, self-serve with no sales call. - Mark Standard: $1,500/mo or $15,000/yr. 100,000 AI-output items per month. - Mark Growth: $4,000/mo or $40,000/yr. 500,000 AI-output items per month. - Enterprise: unlimited AI-output signing with no monthly allowance cap, all add-ons included, custom SLAs. Identity: every paid plan includes a CAWG identity certificate, pending enrollment and program approval. White-label identity, private key issuance from the Encypher root Certificate Authority, is a paid add-on. Licensing revenue share is flat across tiers: coalition-brokered deals send the majority to the publisher with exact terms in the coalition agreement, and direct deals a publisher negotiates are 100% theirs. ## Who we serve - [Publishers](https://encypher.com/solutions/publishers): Confirm domain control, then sign content as it leaves the CMS with the applicable W3C ODRL rights profile bound at signing time. Meter records bounded evidence of use for licensing review, and Trace identifies which distributed copy a leak came from. - [AI companies](https://encypher.com/solutions/ai-companies): Sign completed outputs for EU AI Act Article 50 marking, never per streaming chunk. Verify generated quotes against a signed source before publication. Report which signed sources were retrieved, grounded, and cited behind a completed answer, each carrying a rights verdict for the named use. - [Enterprises](https://encypher.com/solutions/enterprises): Sign completed outputs through one shared API contract across business units and formats. Seal final reports, filings, and evidence packages. Measure marked, submitted, and failed outputs by application so legal and governance teams can see where the control is active. ## Rights management - [Rights management](https://encypher.com/rights-management): A deterministic, fail-closed W3C ODRL 2.2 policy engine, odrl-engine/0.1.0. It takes a licensing policy plus an intended use and returns a machine-readable verdict. Engine guarantees: - Deterministic: the same policy and the same intended use return the same verdict every time, with the engine version and SHA-256 hashes of the policy and request in each response. - Fail-closed: ambiguous, malformed, unsupported, or over-limit input resolves to deny, never to grant. - Prohibition wins: when a permission and a prohibition both match, the prohibition takes the decision. - Defaults to deny: no matching rule means no signal, and no signal means no. - Dependency-free: pure evaluation, no network call or third-party rules library. Rights tiers: Bronze covers crawling and scraping, Silver covers RAG and retrieval, Gold covers training and fine-tuning. Verdicts: permitted, permitted_with_duties (obligations such as attribution or payment come back named), prohibited, no_matching_rule (denied by default), and invalid. Engine surfaces: - POST /public/rights/odrl/evaluate: public evaluation, no key required, rate limited per IP. - GET /public/rights/{document_id}/odrl: the W3C ODRL policy bound to a signed document, resolved at signing time. - POST /verify/advanced?intended_use=: authenticated verification that returns a clearance for an intended use (ai_training, ai_inference, data_mining, scraping, or rag_retrieval). - GET /public/rights/organization/{id}/rsl: RSL 1.0 XML for tools that expect it. RSL 1.0 compatibility: Encypher emits and imports RSL 1.0 XML and publishes robots.txt additions and rights-discovery meta tags. There is no RSL evaluation engine and no RSL schema validation; every decision runs on W3C ODRL. An OLP token is an advisory handshake, never a permission grant. ODRL 3.0 is not a published W3C specification and is never claimed. ## Content provenance and the EU AI Act - [Content provenance](https://encypher.com/content-provenance): Cryptographic proof of origin embedded directly in content at creation, so it travels with the content wherever it goes. Encypher signs and verifies 44 media types across images, audio, video, documents, and fonts, plus text via the C2PA standard for unstructured text. - [EU AI Act and content provenance](https://encypher.com/content-provenance/eu-ai-act): EU AI Act Article 50 sets transparency requirements for AI-generated content. C2PA manifests provide the machine-readable marking the rules call for. Article 50 applies August 2, 2026 for new systems and December 2, 2026 for systems already on the market. The EU Code of Practice on Transparency of AI-Generated Content was published June 10, 2026. ## Format support Encypher signs 44 media types across images, audio, video, documents, and fonts, plus text. Twenty formats formally passed the C2PA Conformance Program v0.1, the maximum any product can hold under that version. Text uses invisible Unicode variation-selector encoding with sentence-level Merkle trees signed with Ed25519, surviving copy-paste and redistribution. Images, audio, video, and PDF carry JUMBF/COSE C2PA manifests. Microsoft Office formats, DOCX, XLSX, and PPTX, sign under C2PA 2.4 and verify version-agnostically through the same Mark API. They are supported formats, not formal C2PA Conformance Program formats. ## C2PA standard and conformance - [C2PA standard](https://encypher.com/c2pa-standard): The open standard for content provenance, backed by 400+ member organizations including Adobe, Microsoft, Google, BBC, Reuters, OpenAI, Qualcomm, Intel, Arm, NVIDIA, Sony, and Truepic. C2PA is a standards body governed as a community specification under the Joint Development Foundation, not a platform or a certification body. C2PA 2.4 is the current specification. - [C2PA members](https://encypher.com/c2pa-standard/members): Who is building the standard and why the coalition matters. - [The C2PA standard for unstructured text](https://encypher.com/c2pa-standard/section-a7): The text-provenance section Encypher authored, published January 8, 2026. - [C2PA conformance](https://encypher.com/c2pa-standard/conformance): The conformance program and Encypher's four-category result. - [Trust and conformance](https://encypher.com/trust): Encypher passed the C2PA Conformance Program in all four categories, generator, validator, certificate authority, and time stamp authority, on June 30, 2026. Encypher's C2PA Root and Issuing CA are on the official C2PA CA Trust List, and its TSA is on the official C2PA TSA Trust List. Verify against the official C2PA Conformance Explorer. ## Identity (CAWG) Every paid plan includes a CAWG identity certificate, pending enrollment and program approval, that can assert organization, personal, and multiple identities in one manifest through CAWG identity assertions. White-label identity, a private signing key issued from the Encypher root Certificate Authority, is a paid add-on for teams that want tool identity plus organization identity. The C2PA manifest carries the full X.509 certificate chain, so any party that trusts that chain can verify the signature without a central registry. ## Tools - [Verify content](https://encypher.com/tools/verify): Free tool to verify text and file provenance; paste signed text or upload images, audio, video, and documents to inspect embedded C2PA credentials. No account required. - [Sign content](https://encypher.com/tools/sign): Free C2PA signing tool. - [WordPress plugin](https://encypher.com/tools/wordpress): Auto-sign content on publish. - [Chrome extension](https://encypher.com/tools/chrome-extension): Verify provenance while you browse. - [Signed AI chat demo](https://encypher.com/chat): A live chat whose AI answers are signed with C2PA provenance, so each response can be independently verified. - [EU AI Act Article 50 readiness check](https://encypher.com/tools/eu-ai-act-readiness): Free questionnaire mapping an organization's likely Article 50 transparency duties, with a one-page PDF report. - EU AI Act readiness API for agents: `GET https://encypher.com/api/tools/eu-ai-act-readiness` is a free, unauthenticated JSON API. Called with no parameters it returns a self-describing specification of every parameter and allowed value. Construct a parameterized URL (for example `?role=deployer&euNexus=yes&exposurePaths=generate&contentTypes=text&disclosure=visible&evidence=partial&status=planning`) and receive a scored readiness result: a 0-100 score, the applicable Article 50 obligations with per-obligation status, prioritized actions, and days to the August 2, 2026 deadline. All parameters are optional; omissions lower the result's stated confidence.

A: Encypher is content provenance and rights infrastructure. It authored the C2PA standard for unstructured text and co-chairs the C2PA Text Provenance Task Force. Its products, Mark, Meter, Trace, and Seal, attach portable provenance, organization identity, and machine-readable rights terms to content and AI outputs, with free verification for anyone. Q: What are the four products? A: Mark attaches portable provenance and rights terms to content and AI outputs (available now). Meter produces bounded source-use reports (early partner program). Trace embeds a recipient-specific marker so a leak resolves to its copy (available now). Seal binds an integrity record so recipients detect changes after signing (available now). Q: What does Encypher cost? A: The Free tier includes 1,000 declared AI-output items and 5 EU AI Act Article 50 compliance certificates per month. Mark Starter is $99/mo or $990/yr for 10,000 items, Standard is $1,500/mo or $15,000/yr for 100,000, Growth is $4,000/mo or $40,000/yr for 500,000, and Enterprise is unlimited. Every paid plan includes a CAWG identity certificate pending enrollment and program approval; white-label root-CA key issuance is a paid add-on. Q: Does Encypher stop AI companies from using my content? A: No. Encypher reports provenance and returns a deterministic permit or prohibit verdict; it is not an enforcement mechanism and does not gate traffic. A customer's own retrieval layer decides what to do with the verdict. Q: What is the rights engine? A: A deterministic, fail-closed W3C ODRL 2.2 engine (odrl-engine/0.1.0) that maps your Bronze, Silver, and Gold terms plus an intended use to a machine-readable verdict. It is RSL 1.0 compatible for emit and import, but every decision runs on ODRL. ODRL 3.0 is not a published W3C specification and is never claimed. Q: Do rights terms prove I own the copyright? A: No. Rights terms are supplied evidence of the terms you publish, and domain verification supports authority to publish those terms. Neither proves legal ownership of the underlying work. Q: What media types are supported? A: 44 media types across images, audio, video, documents, and fonts, plus text; 20 formally passed the C2PA Conformance Program v0.1. DOCX, XLSX, and PPTX sign under C2PA 2.4 and verify version-agnostically, but they are not formal C2PA Conformance Program formats. Q: Is verification free? A: Yes. Verification is free across all media types with no authentication required. Any third party can verify any signed content at no cost. ## Contact - Website: https://encypher.com - API documentation: https://api.encypher.com/docs - Email: contact@encypher.com - Sales: sales@encypher.com ## Full site index Complete deep-link index of every public page on encypher.com, 174 URLs, generated from the site's own route table and content registries at build time.
