About Art50
Art50 is compliance software designed to establish tamper-evident records of human editorial review for AI-assisted content under EU obligations. Each log entry is hashed into an append-only chain, ensuring that records remain verifiable and tamper-resistant. Users can export self-describing proof files for independent validation without vendor lock-in. The platform supports automated workflow logging via a REST API, OpenAPI specifications, Zapier, and Make, and is hosted entirely in the EU.
