Turn what you need to remember into your own flashcards. LessonNow offers flip cards, type-in answers and image occlusion, with a review schedule that adapts to how well you remember, so you can pick up where you left off every day. • Create text and image flashcards, organize them into decks and review them as they come due. • Flip cards, type-in cards and image occlusion. AI can also turn your notes, slides or photos into card drafts, and even mask the labels on diagrams for you. • FSRS spaced repetition estimates your memory after every answer and schedules the next review just before you would forget. • Read-aloud in many languages, with automatic voice switching for mixed-language cards. • Cards and review history are stored on your device; after your first sign-in you can study offline while your session is active. • Local backup export and import, and daily review reminders. • Classic and Plus remove the deck and card limits and, once you authorize it, back up and sync through your own Google Drive.
