A collection of Pope Leo XIV's writings has been officially certified as human-authored by Proudly Human, an Australian company, following accusations that parts of his anti-AI encyclical were generated by artificial intelligence. The certification covers Maps of Hope, a book of reflections on education and AI, published shortly after his encyclical Magnifica Humanitas warned of AI's threats .
After the encyclical's release, AI researcher Linch Zhang argued that elements such as frequent em dashes and rhetorical triads suggested AI involvement, possibly via Anthropic's Claude . Pangram Labs flagged some passages as AI-generated, though the Vatican never confirmed the claims .
Proudly Human, led by Australia's former chief scientist Alan Finkel, verified the text using a suite of four or five AI detectors plus an averaging algorithm . Authors must pass an ID check and declare no AI was used for drafts or sentences . The company's verdict: "basically purely human" .
Critics note that AI detection is unreliable; detectors can disagree or falsely flag human text . The Atlantic has warned against over-trusting such tools. However, Finkel argues that absent regulation, certifications offer readers "a fundamental right" to know authorship, especially for religious figures .
