I'm a teacher and this is the simple way I can tell if students have used AI to cheat in their essays

With ChatGPT and Bard both becoming more and more popular, many students are being tempted to use AI chatbots to cheat on their essays. But one teacher has come up with a clever trick dubbed the'Trojan Horse' to catch them out. In a TikTok video, Daina Petronis, an English language teacher from Toronto, shows how she can easily spot AI essays. By putting a hidden prompt into her assignments, Ms Petronis tricks the AI into including unusual words which she can quickly find. 'Since no plagiarism detector is 100% accurate, this method is one of the few ways we can locate concrete evidence and extend our help to students who need guidance with AI,' Ms Petronis said.
