Google’s revisions
Independent Drive save history, not a style model’s guess.
Authorship Certificate Registry, operated via Ammati, issues a £29 process certificate from this Google Doc’s Drive revision history. It stores revision metadata and a hash. It does not store the manuscript, and it does not decide whether the writing is AI. Anyone can check the verify link. No account.

Pay, then share the Doc as Commenter with the registry inbox.
Registry seals the record
Drive revisions, growth, editors, payload hash. No manuscript stored.
Anyone verifies
Public verify link. No account. No opinion from a person.
Detectors guess from finished prose. Authorship never claims “this was written by a human.” It certifies the process record Google already keeps on the file, then publishes a verify page your client can open themselves.
The authority is the sealed record (Drive metadata + cryptographic hash + public check), not a reviewer deciding on AI.
First five certificates are £19 if you allow a short public quote after. Fewer than three useful Drive revisions: full refund. The registry will not issue a thin certificate.
One Google Doc. Sealed certificate + public verify URL. Typical issuance within 48 hours.
