GPTZero

GPTZero is a classification model that claims to be able to quickly detect if text was generated by OpenAI’s ChatGPT, GPT3, GPT4, or Google’s Bard. After submitting text, GTPZero spits out a score specifying the probability that a document was potentially AI-generated. GPTZero says its tool can be used to analyze a wide assortment of English prose though the most apparent use case appears to be for educators trying to determine if students are using AI to breeze their way through essays.
More than 6,000 teachers from Harvard, Yale, and the University of Rhode Island have reportedly used the tool according to The New York Times.
