I'm taking a university course right now and one of the big textbook companies (McGraw-Hill, Macmillan, one of those) has an "AI Tutor" on their homework assignment.

It's somehow LESS helpful than just having a pointer to which part of the text to revisit.

It basically just restates the question/problem. Even worse than that is that it's an essentially STATIC note for each question yet it appears to be REAL-TIME GENERATED each time. I guess that could just be for appearances but it's just dumb all the way around really.
