Princeton student says his new app helps teachers find ChatGPT cheats

A Princeton University student has built an app that helps detect whether a text was written by a human being or using artificial intelligence tool ChatGPT.

Senior Edward Tian, a computer science and journalism major, said in a recent tweet that the algorithm behind his app, called GPTZero, can "quickly and efficiently detect whether an essay is ChatGPT or human written." The beta version of the app is available here.

ChatGPT has exploded in popularity recently for its ability to spit out coherent essays on virtually any topic in just seconds. The technology has drawn interest from investors, with the Wall Street Journal reporting that parent company OpenAI could soon attract investments valuing it at $29 billion.
