Like co pilot on Edges mobile browser? That would be pretty cool. I could see people getting use out of it.

I was using an app to study for a quiz for an upcoming job, Quizlet. They let you make your own flash cards or share them online then you can ask AI to provide more details.

For example the flash card might be a question one side and answer on the other, but you could ask AI to explain why that's the answer with more detail.
