Cogni is a flashcard app with FSRS spaced repetition, AI flashcard generation and Anki deck import. 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. NOTES NEXT TO YOUR CARDS Generate study notes together with your cards and read them in Cogni on the web, linked to the cards they produced. READY-MADE DECKS Browse a library of 5,000+ decks for languages, medicine, anatomy and more, add a deck and start studying. BUILT FOR - Medical, nursing and pre-med students - Language learners building vocabulary - Students preparing for exams - Anyone moving their decks from another flashcard app FREE TO START Create cards, import decks, sync and study up to 40 card reviews a day for free, and try one AI generation.
