Remember everything you learn, in less study time. Every month, 18,000+ students turn notes, photos and PDFs into cards and review them with spaced repetition (FSRS). Azri (formerly Simple Anki) uses the FSRS algorithm, the most advanced spaced repetition scheduler available, to predict exactly when you will forget each card and schedule your review at the perfect moment. The result is 90%+ long-term retention with less study time. CARDS THAT MAKE THEMSELVES Stop building decks by hand. Give Azri your material and it writes the cards for you. Paste your notes or type a topic — Azri turns it into a deck in seconds. Snap a photo, drop in a PDF, or record a lecture — Azri pulls out the text, you review and edit it, then it generates the cards. Pick a card style or create your own, so every deck matches how you study. Add AI pronunciation audio to the front of your cards, generated automatically when you save. SMART FLASHCARDS Azri goes beyond basic flashcards. It tracks the stability, difficulty, and retrievability of every card, then automatically adjusts your schedule based on how you actually perform. No manual intervals. No guessing. Add images and audio to make concepts easier to remember. Use a rich card editor with LaTeX for formulas, auto-translate, and multilingual keyboards. Organize your learning with color-coded decks and folders. Choose card layouts that fit your study style: front-to-back, back-to-front, or combined. STUDY YOUR WAY Study in a way that matches how you learn and what you need to retain. Spaced repetition with science-backed scheduling that targets long-term memory. Quiz mode for active recall with instant feedback. Typing practice to lock in answers by typing them out — with character-by-character feedback that even catches missing accents. Shuffle or sequential study order for maximum focus or consistency. Track retention rates, streaks, and your review history to see progress over time. NOW ON THE WEB Azri isn't just on your phone anymore. Open any web browser on your computer, scan the code with your iPhone camera to sign in, and pick up exactly where you left off. Review your cards on a bigger screen and build or edit decks with a full keyboard — everything stays in sync across your devices. (Available with Azri Pro.) IMPORT & SYNC Already use Anki?
