Type what you want to learn, or upload your notes, and the cards are written for you. Study with spaced repetition, on your phone or in the browser, with or without internet.
Describe a topic in one line and the AI writes the set. Or upload a PDF, Word or PowerPoint file, or photograph textbook pages and handwritten notes, and the cards are made from that. You can also write cards yourself and let the AI fill in the back.
FSRS spaced repetition decides when each card comes back: you review what is due and leave the rest for later.
Learn with spaced repetition, browse or view the whole set, shuffle for a random pass, or test yourself by typing the answer or with a multiple-choice quiz. Cards can be read aloud with your device's voices.
