Studyh

Brazilian web app for active studying for college and the ENEM exam. It turns PDFs and lectures into questions and flashcards with spaced repetition, asks students to explain topics out loud with a mastery score, and unlocks a recorded lecture's summary only after the questions.

It includes a whiteboard for notes, writing assignments in ABNT format and real exam questions with explanations. The text and answers always belong to the student. It is free to start.
