Client said it’s AI. Issue a process certificate.
Authorship does not decide if writing is AI. It seals a certificate from this Google Doc’s Drive revision history — hashed and checkable by anyone. Not a detector score. Not a personal review.
Rush issuance
£49
Same certificate, 24-hour target. For when an invoice is already blocked.
Rush certificateWhat the certificate contains
- Drive revision timeline from Google — independent of any reviewer.
- Document size growth over time.
- Accounts that created and edited the file.
- Cryptographic payload hash — so the sealed record can be checked.
- Optional: declared grammar/structure passes, if logged separately.
Authorship certifies process metadata. It does not detect AI and does not claim a human typed every word. Drive history can be padded; it is still harder to fake than a detector screenshot, and clients can verify it themselves.
How issuance works
- Pay. Share the Doc as Commenter with the registry inbox.
- The registry reads revision metadata only — never stores the manuscript.
- You receive a certificate ID and a public verify URL for your client.
- Fewer than 3 useful revisions? No certificate — full refund.
Verify without an account
