Man of his word: Pope Leo speeches declared human-authored by Australian AI detection tool

Proudly Human, an Australian firm led by former chief scientist Dr. Alan Finkel, completed an analysis of Pope Leo XIV’s speeches and writings in collaboration with the publisher, Australian Catholic University, and Vatican officials. The collection was certified as human-authored within a day of review.

The certification came shortly after the pope’s encyclical Magnifica Humanitas warned of artificial intelligence posing significant risks to humanity. In that document, church leadership expressed concerns about AI technology becoming dominant and concentrated in few hands. The encyclical advocated for AI development that remains “human-friendly” and accessible while remaining subject to public discussion.

Proudly Human’s certification process requires authors or representatives to complete identity verification and declare compliance with standards prohibiting AI from drafting initial versions or generating sentences and paragraphs. The company employs multiple detection tools that analyze writing patterns and grammatical characteristics, supported by its own algorithmic analysis. Finkel stated the detection suite undergoes nightly testing to maintain accuracy.

Finkel characterized the certification as providing transparency to readers about authorship origins, framing disclosure as a fundamental right for audiences. He emphasized this holds particular weight in religious contexts, where congregants expect the teachings they receive represent genuine human expertise and wisdom. Leadership at Australian Catholic University noted value in providing definitive assurance of human authorship given the volume of machine-generated content currently circulating online.

The company’s terms indicate certifications are issued based on provided information and completed verification processes, with provisions for refusal or revocation if materials misrepresent authorship or fail to meet published standards.
