Proudly Human, an Australian-based certification service, verifies that books and cultural products were made by people rather than AI. Authors attest that their AI use was de minimis, and manuscripts are screened through four commercial AI detectors.
Why it matters
As AI-generated text becomes harder to distinguish from human writing, certification offers readers and publishers a way to verify authorship. The idea grew out of Alan Finkel's own book, which he finished months after ChatGPT was released.
Certification uses four commercial AI detectors, with a passing score below 10% AI-generated and a failing score above 30%, while scores in between prompt a conversation with the author. The service's accuracy on borderline manuscripts has not been established in the source material.

The details
Certification costs $60 per title and is paid only on approval, while journalists can be certified for $10 a month. The company tests its detectors nightly against books known to be human- or AI-written, and the Big Five publishing houses are reportedly in talks with Proudly Human.

The Tech Race
Proudly Human's certification extends the Authors Guild's Human Authored mark, which already appears on about 6,500 books, by adding a paid, detector-based verification alongside it. The service positions human authorship as a market differentiator in an era of commercially available AI writing tools.
Readers who want assurance that a book was written by a person can look for certification marks, and certification costs $60 per title paid by authors only on approval. Journalists can be certified for $10 a month, which may affect how bylines and reporting are verified.
The takeaway
Certification services are likely to face a shakeout, according to Finkel, so readers should expect the market for human-authorship verification to change. Checking which mark a book carries can help readers judge its origin.
