Your writing has a story.
Plumelin certification connects a manuscript version to documented elements of its writing process. A point of reference that its recipients can verify.
A documented process
Elements are recorded during writing, then checked against the certification rules.
A specific version
The certificate covers the elements validated for the relevant manuscript version.
Verifiable evidence
A cryptographic signature lets recipients check the origin and integrity of the signed information.

As AI-generated books become more common, being able to account for your writing process matters more.
Certification provides concrete evidence about the process observed in Plumelin. It gives authors a way to share a record of their work, connected to the manuscript they send.
It does not guarantee that no AI was used, that the text is original or that its author holds the rights. It covers the documented method and the elements actually checked.
