GoodOff

GoodOff turns your notes, PDFs, slides, lectures, web pages and YouTube videos into editable flashcards and quizzes, then schedules every review with FSRS-6 spaced repetition so cards return right before you forget. The free plan covers hand-made decks, cards and quizzes, Anki import, and AI decks, quizzes, study guides and FAQs within daily, weekly and monthly limits. Pro is $20/mo or $120/yr, with a 7-day trial on the yearly plan, and adds podcasts, video overviews, slides, practice exams and Sage, a tutor that answers from your own notes and cites the source.

Available on iOS, Android and web, for high school, college and grad students, exam takers and lifelong learners.
