Art50 Compliance provides a platform for EU organizations to document and prove human review of AI-generated content, as required by the AI Act's Article 50 transparency obligations. The service creates tamper-evident, independently verifiable records by hashing each review into an append-only chain anchored in Sigstore's Rekor. It is free for journalists, non-profits, and government bodies, with paid plans for other organizations.

Problem
Under the EU AI Act's Article 50, organizations must disclose AI-generated content and demonstrate that a human has reviewed it before publication. Many teams lack a structured, verifiable way to capture and prove this human-oversight work, leaving them exposed to compliance risk and unable to show a defensible audit trail if questioned.
Solution
Art50 Compliance offers a platform that lets teams review, seal, and export proof of human oversight for AI-generated text, images, audio, or video. Users log each review with timestamps and details of what was checked, and the platform hashes each entry into an append-only chain that is independently anchored in Sigstore's Rekor, making any post-hoc alteration immediately detectable. The service is hosted entirely in the EU, and records can be exported as self-describing proof files that anyone can verify without relying on Art50's infrastructure. An API and no-code integrations with Zapier and Make allow teams to log reviews directly from their existing content production workflows.
Target Audience
Primary customers are EU-based agencies, publishers, in-house content teams, and any organization deploying AI-generated content that needs to demonstrate Article 50 compliance. The platform is also free for journalists, newsrooms, registered charities, NGOs, and public authorities.
