Limits and review
An AI overview can omit details or misunderstand emphasis. It helps you navigate the document; it does not replace reading the full lecture.
Paid AI tasks deduct US-dollar AI balance based on actual usage. Ordinary reading and note editing do not use AI balance. See pricing and free features
