I honestly think that teachers and professors can't take the risk of using those AI-detection tools as they are too unreliable in their current state. As more and more advanced and personalized text-transformers emerge, it's just going to get harder from here on, if not impossible, to detect. With the right prompts, you can create several stories that will be assessed as 99% human by the detection tool. But you can also try to imitate the writing of GPT, which will be assessed as AI generated.
