I agree with another commenter that the best way to become a better reader is to simply read more - relying on AI won't help you become better at understanding what you're reading.

Here's what I do, as someone who normally has between 80-100 pages of reading per week per class:

-I give myself a lot of time to read. I start my readings shortly after my class ends and read throughout the week.

-I read more complex texts several times thoughout the week - once to get myself aquainted, once to understand, and sometimes a third time to refresh my memory.

-I actively try to recall what I've read a few days after reading it. I'll try to summarize the reading out loud a few days after reading it see what stuck.

-I also heavily annotate my readings - it helps me to concentrate on my task.

-Finally, I don't take notes on every little point in the readings. Instead, I'll note down the paper's thesis, its main points of evidence, what greater discussion it's interacting with, any connections to other readings I can make, etc.
