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

A collection of speeches and writings attributed to Pope Leo XIV has received certification as human-authored from Proudly Human, an Australian firm led by former chief scientist Dr. Alan Finkel. The review was conducted in collaboration with the publisher, Australian Catholic University, and Vatican cardinals.

The certification comes less than two months after Leo issued his first encyclical, Magnifica Humanitas, which expressed concerns about artificial intelligence and advocated for the technology to be prevented from dominating humanity. In the document, the pontiff called for AI to be made human-friendly, universally accessible, and subject to open discussion and debate.

Finkel reported having substantial confidence in the process before reviewing the collection and stated that Proudly Human certified the materials as human-created within one day. The certification process requires authors or their representatives to complete identity verification, sign a declaration confirming minimum standards are met, and confirm that AI was not used to generate initial drafts or individual sentences and paragraphs. The company employs multiple AI detection tools that analyze various aspects of writing and grammar, combined with an averaging algorithm that is tested nightly.

Finkel expressed that transparency regarding authorship should be considered a fundamental right for readers, particularly when consuming religious or spiritual content where authenticity of voice carries particular significance. The Australian Catholic University president and vice-chancellor, Prof Zlato Skrbis, noted that given the volume of content generated rapidly online, providing certified confirmation of human authorship offers meaningful value to audiences seeking assurance of authentic human judgment and reflection in published works.
