It's really difficult to plagiarize if you write the paper or take the exam in class using paper and pen-or-pencil. It's also difficult to plagiarize if the teacher/professor/TA actually wanders around the room during the test (without stopping behind a student and raising the student's blood pressure in the process.)
Of course, that involves more on your part as teacher/professor -- you actually have to teach and test and act as editor -- on an ongoing basis. At university, that's part of what TA's are (or should be) expected to do. As a teacher, it's your responsibility.
So, if you happen to be a CS 101 instructor ask for the evolutionary copies of a program. If you happen to teach poetry and cover Herrick, ask for an original poem in the style of "Upon Julia's Dress" and see what the students happen to see from the same poem.
Teaching without ensuring that learning happens is a waste of time and a disservice to your profession.
It seems to me that AI detection is best done in the editor itself. If you track a student's mouse and keyboard there should be a clear distinction between someone plagiarizing (even if they're re-typing word for word) vs writing genuine work - which would involve lots of backtracking and editing.
