A recent study focused on evaluating the effectiveness of a commercial AI content detection tool called Pangram. Researchers tested it by submitting a large number of articles, some written entirely by humans and others generated by artificial intelligence. The goal was to assess how well Pangram could distinguish between human and AI-generated text. In the tests involving human-written articles, Pangram performed very well, identifying 450 out of 460 articles as completely human-written. It also detected nine articles as mainly human but with some sections generated by AI. Only one article was incorrectly labeled as mainly AI-generated, which was a false positive. Some of the human-written articles had never been published online, making it difficult for the detector to recognize them, as they were final drafts of articles not yet available to the public. For AI-generated texts, 570 articles were submitted to Pangram, including 350 different texts created by AI. Researchers sometimes used multiple versions of the same text to better understand how the detector worked. The results showed that Pangram was able to correctly identify 95% of the AI-generated texts, indicating a high level of accuracy in detecting AI content. The study was conducted using a corpus of technical articles, which are typically detailed and structured, making them a good test case for AI detection tools. The findings suggest that Pangram is a highly effective tool in identifying both human and AI-generated content, though it is not perfect, as seen in the one false positive and the difficulty in identifying some unpublished human-written texts.
