About Cardvoo
Cardvoo is a flashcard app for students who want to remember what they study, not just cram it. Drop in a PDF, slide deck, Word doc or your own notes and AI turns it into a ready-to-study deck in seconds. A modern spaced-repetition scheduler (FSRS) brings back each card right before you'd forget it, so you study less and retain more. Reviewing doesn't have to be a grind. Switch into mini-games, take practice tests with AI-graded written answers, or challenge a friend to a live 1v1 Recall Race. The free plan runs AI on your own device, with no signup wall or credit card. Standard and Pro unlock cloud AI, unlimited modes, podcast-style audio review and more.
