SuperMemo is learning software for Windows built on 📝spaced repetition. Its own timeline dates the start of its memory research to 1984 and the founding of SuperMemo the company to 1991. Its latest version, SuperMemo 20, brings together spaced repetition, PDF reading and AI explanations in one place. The earlier SuperMemo 19, sold at a lower price, combines spaced repetition with incremental reading.
The manual of the flashcard program 📝Anki credits SuperMemo with pioneering the concept of a system that keeps track of the ideal time to review material, and bases Anki's own scheduling on SM-2, an older version of the SuperMemo algorithm. The company's supermemo.com site presents SuperMemo today as a language-learning app, offering 25 languages and nearly 300 courses through App Store and Google Play apps and on the web, with an AI tutor in Live mode and conversation practice in MemoChat, which it describes as interactive dialogues powered by AI. This memo covers the SuperMemo software sold through supermemo.store.
