Anki

Anki is a spaced-repetition flashcard system for long-term learning. It organizes questions and answers into decks for languages, medicine, exams, and job training. During review, learners rate how well they remembered each answer. The system then schedules each card for another review at a suitable time. Cards support text, images, audio, video, and scientific notation. Users may change card layouts and review timing to match different subjects. Sync keeps study material available across devices. Add-ons and shared decks provide extra features or ready-made collections. Anki suits students, teachers, researchers, and others who need to retain detailed information. It supports repeated review but does not replace understanding or practical work. Its structured schedule keeps attention on material that needs steady practice.
