Turn anything into flashcards. Paste a link, drop a PDF, Word or PowerPoint file, snap a photo, or point it at a YouTube video: ten cards in about a minute, and every card shows the line it came from and whether the source actually says it. Or pick one of 6,119 ready-made decks. Free, no account, no ads. THE LIBRARY 6,119 ready-made decks across 358 subjects: USMLE, NCLEX, MCAT, medical terminology, AP courses, SAT vocabulary, 20+ languages, licensing exams, geography, history and more. Search everything, browse by subject and level, and study a deck the moment you tap it. Adding a deck saves your own editable copy. CARDS FROM YOUR OWN MATERIAL - Paste notes, drop a PDF, Word or PowerPoint file, take a photo of a page, or paste a web link or YouTube video - Every AI card quotes its source and is checked against it before you see it - Question and answer, fill in the blank, both ways, and multiple choice with wrong answers that are actually plausible - 10 generations free; more come by the pack, never as a subscription HONEST SCHEDULING - Spaced repetition that brings each card back just before you would forget it - A daily limit: whatever is past it waits for tomorrow, so a day off never becomes a backlog - How much you remember, shown as a real percentage, not a streak - Ratings show their consequence: Again means the card comes back before the session ends PRACTICE AND TEST - Practice: go through every card and sort it into Know it or Still learning, round after round until you know them all - Test: multiple choice, written and true or false questions made from your deck, scored at the end or as you go - Practice the ones you missed in one tap - Neither one changes your review schedule TEACH-BACK (PRO) Say the answer out loud before the flip.
