Generic flashcard decks teach the average student. Cards built from your own notes teach you.
There's a reason pre-made flashcard decks feel slightly off, even when the subject is right: they were written for a hypothetical average student, not for you. StudyHubs turns your own notes, lecture recordings, and readings into flashcards instead, so the language and framing match how you actually learned it the first time.
The cards also improve as you use them. Ones you consistently get right fade into longer review cycles. Ones you hesitate on come back sooner, and eventually the AI rewrites them from a different angle if the original phrasing keeps tripping you up.
