built a simple study app that turns messy notes (images or text) into flashcards + quizzes using gpt-4o.

originally made it to help myself focus while studying. launched with a hard paywall to avoid ads or noise.

~60 users so far, mostly from tiktok. curious if this is useful beyond my own use case?
