Student Builds ChatGPT Detection App to Fight AI Plagiarism

Educators concerned that the viral popularity of OpenAI's ChatGPT will lead to waves of generic-sounding, mostly AI-written essays might have reason to relax. Princeton student Edward Tian devoted a portion of his holiday to writing GPTZero -- an application that can identify text authored by artificial intelligence. Tian posted a couple of proof-of-concept videos on January 2nd demonstrating GPTZero's capabilities. First, it determined that a human authored a New Yorker article; then, it correctly identified ChatGPT as the author of a Facebook post. GPTZero scores text on its "perplexity and burstiness" – referring to how complicated it is and how randomly it is written.
