All Chegg has going for it is a database of answers for homework assignments that typically use per-student randomized numbers—so students have to recalculate their specific answer manually by following the steps—and "verified tutors" that constantly give wrong answers to even highschool-level math questions.
Every college student I know uses ChatGPT (and now DeepSeek) for tons of assignments, usually via the free plan.
Once you experience that, it gets really tempting to cancel that $20/month chegg subscription and never look back.
I find professors pitiful fearmongering over 'the big bad ChatGPT' a little funny, such as when they insist they "have secret tools to detect AI usage" and "it can't answer the questions correctly anyway", so "you shouldn't even try it".
