Study on iPhone, iPad, Android and the web: your decks and progress sync through one account, and reviews work offline. MAKE FLASHCARDS WITH AI Upload a PDF, photograph your notes or textbook pages, upload a lecture recording, paste text or type a topic. Cogni drafts question-and-answer and cloze cards. You check the drafts and keep the ones you want. FSRS SPACED REPETITION Every card is scheduled with FSRS, the open-source algorithm that predicts when you are about to forget. After each answer, rate your recall (Again, Hard, Good or Easy) and see when the card comes back. Each day you review only what is due. IMPORT YOUR ANKI DECKS Save an .apkg file in Files, tap + in Cogni and choose “Import .apkg”. Cards, subdecks, cloze cards, images and audio come with it. Anki's review history stays in Anki: FSRS builds a new schedule from your answers in Cogni.

Practice on Apple Watch for quick due-only sessions on the go. Focused Practice Tap to flip, then mark answers to keep moving. A short sound plays when you mark a card, and you can look over every card when a session ends.
