GPTZero can tell if an essay about Hamlet was written using a bot.

High school English students who were hoping to use artificial intelligence to write their homework have a new enemy: Edward Tian, a 22-year-old senior at Princeton University, who created a website that can detect if a piece of writing has been created using the AI tool ChatGPT.

Meanwhile, instructors everywhere are rejoicing. “So many teachers have reached out to me,” said Tian, whose recent tweet about his tool, GPTZero, went viral. “From Switzerland, France, all over the world.”

The latest version of ChatGPT, called GPT3, was released to the public in late November. The tool is able to produce amazingly coherent writing, which has endless possibilities, ranging from wonderful things (like allowing a pool installer with dyslexia to communicate effectively with his customers over email) to more nefarious uses.
