AI made authorship a question. The EU just made it a €15M problem.
EU AI Act Article 50 transparency obligations in force. AI-generated text, image, audio, and video placed in the EU market must carry machine-readable provenance — with a narrow editorial-responsibility exemption for text under 50(5).
Per violation. Applies to any company placing content in the EU market, regardless of where they're headquartered.
C2PA and Content Credentials exist but don't bind content to a real human, don't capture AI-involvement metadata, and don't carry an editorial-responsibility attestation. RealStamp does — and ships today.
A portable seal. Hardware-bound. Standards-based. Article 50-ready.
Every stamp is built from a vertical stack — each layer adds a property regulators and platforms now require. RealStamp ships the full stack today.
Hardware-bound human signature.
Face ID + Secure Enclave on iOS, biometric + Android Keystore on Android. WebAuthn liveness. FIDO2 Level 3-equivalent — mathematical proof a real human signed.
AI-involvement metadata.
The signer declares the role AI played: human-only, AI-assisted, AI-generated-edited, or AI-generated-responsible. Captured at signing, bound to the credential, surfaced on verification.
Editorial-responsibility attestation.
A human-named legal hook satisfying the EU AI Act's Article 50(5) editorial-responsibility exemption for AI-generated text — directly, in production today.
C2PA assertions, emitted.
RealStamp emits standards-compliant C2PA AI assertions alongside the SD-JWT credential, anchored to the Sigstore Rekor public transparency log used by Google's software supply chain.
Identity + verification, anywhere.
W3C SD-JWT credentials, OIDC identity provider, embeddable verification badge. Verifies in any browser without an account — and the free Article 50 readiness checker is live at /api/article-50-check.
Works everywhere.
Verify in any browser via W3C SD-JWT. Plugins live for WordPress, Chrome, Safari, Firefox. Native iOS + Android. Embeddable badge for any web property.
August 2026: Article 50 is the cliff. RealStamp is the bridge.
Article 50(5) — AI-generated text.
RealStamp's editorial-responsibility attestation directly satisfies the 50(5) exemption: a named human takes editorial responsibility, cryptographically bound to the text. No AI label required.
Article 50(4) — AI-generated images, video, audio.
The AI-disclosure label is required and RealStamp is not a replacement for it. RealStamp adds the complementary human-accountability layer next to that disclosure — who stands behind it, verifiable by anyone.
Free readiness checker, live today.
RealStamp's Article 50 readiness checker is live and free for any developer or compliance team at /api/article-50-check. A defensible compliance moat — and a wide top of funnel.
Live shipping product. Across every surface that matters.
RealStamp is in production today across iOS, Google Play Store, WordPress, and Chrome — plus a free Article 50 readiness checker any developer can hit. Early-customer entry path: a $2,500 90-Day Compliance Pilot.
Try it yourself.
Free to start. Stamp anything. Verify forever.
iOS app, Shopify integration, WordPress plugin, Chrome extension — all in production today.
Public readiness checker at /api/article-50-check — no signup, no key. Top-of-funnel for every EU compliance team.
Early-customer entry path. Scoped, time-boxed, conversion-oriented — designed for procurement to say yes.
Three layers only RealStamp has.
Hardware-bound human attestation
Anchor content metadata. No human binding. Can be stripped, replayed, or bot-generated.
Face ID + Secure Enclave on iOS, biometric + Android Keystore on Android. Mathematical proof a real human was present at the moment of signing. FIDO2 Level 3-equivalent.
Cryptographically-auditable revocation
None. Once issued, a Content Credential cannot be revoked. Disputed or compromised credentials live forever.
JWS-signed revocation list, published every six hours via pg_cron. Each version's SHA-256 anchored to Sigstore Rekor. Three independent revocation paths (community dispute, user withdrawal, admin override). Anyone can verify revocation status independently.
Verifiable human authorization of agent actions
None. Adobe Content Credentials and C2PA don't address autonomous AI agents.
Patent #2 (USPTO 64/076,892, May 28, 2026) covers the inventive method. Positioned ahead of the agent-accountability wave under EU AI Act, NIST AI RMF, SOC 2, FedRAMP.
These three capabilities are RealStamp-exclusive in the market today. Each is a moat.
