There are so many options that could be done, like:

* for each statement, give you the option to rate how well you understood it. Offer clarification on things you didn't understand

* present knowledge as a tree that you can expand to get deeper

* show interactive graphs (very useful for mathy things when can you easily adjust some of the parameters)

* add quizzes to check your understanding

... though I could well imagine this being out of scope for ChatGPT, and thus an opportunity for other apps / startups.

I'm very interested in this. I've considered building this, but if this already exists, someone let me know please!
