THERE'S A TOOL TO CATCH STUDENTS CHEATING WITH CHATGPT. OPENAI HASN'T RELEASED IT

Summary from the TLDR newsletter

OpenAI has a method that can reliably detect when someone has used ChatGPT to write an essay or research paper, but it hasn't released it despite it having been ready for release for about a year. The company is concerned that the tool would be unpopular with its users and disproportionately affect some groups. The tool is 99.9% effective when there is enough text. However, the watermarks it generates can be erased through simple techniques like having Google translate the text into another language and back or having ChatGPT add emojis to the text and then manually deleting them.
