Three steps to a defensible record
Review
Review the AI-generated content, sign it off, capturing what happened to it, when, and what they checked.
Seal
Each entry is hashed into an append-only and an independently verified chain. Change anything after the fact and the seal breaks, making the record tamper-evident, we cannot edit it or take it back.
Export
Download a self-describing proof file anytime. Anyone can verify it independently; no lock-in, no trust required.
Built to stand up to scrutiny
