About

AI Act Logbook

Features
Read full description

AI Act Logbook helps creators, marketing teams, and agencies assess whether EU AI Act Article 50 transparency obligations may apply to an individual AI-assisted asset — then document that assessment as a clear proof record. DECIDE WITH CONTEXT • Add an image, video, audio file, PDF, or text • Follow guided questions for Article 50 transparency and disclosure duties • Separate machine-readable marking for providers from visible notices for deployers • Receive media-appropriate next steps for images, video, audio, and text DOCUMENT YOUR WORK • Keep an asset preview, file metadata, and SHA-256 verification hash • Export an integrity-protected PDF or JSON record for documentation and audit • See the ruleset version and decision rationale in every record • Check for C2PA / Content Credentials markers; this is a heuristic, not cryptographic validation PRIVATE BY DEFAULT Records stay on your device by default. Private iCloud backup, RFC-3161 timestamps, and Pro web linking are optional. A timestamp request sends only the record hash; web linking sends your email address and purchase proof to our service. START FREE Create 10 documented assessments free, then one free assessment per day. Pro adds unlimited saves and RFC-3161 timestamps with visible verification status. AI Act Logbook is decision support and documentation, not legal advice or an AI detector. The Article 50 ruleset is versioned and currently marked as a draft. You remain responsible for publication decisions. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://www.pysaasnow.com/aiactlogbook-datenschutz Start your first assessment and keep a useful record of how you handled AI transparency.
