anki

Flashcard trainer with spaced repetition

Anki is a program designed to help you remember facts (such as words and phrases in a foreign language) as easily, quickly and efficiently as possible. To do this, it tracks how well you remember each fact, and uses that information to optimally schedule review times. With a minimal amount of effort, you can greatly increase the amount of material you remember, making study more productive, and more fun. While Anki can be used for studying anything, it also ships with special features designed to make studying Japanese and English easier: integrated dictionary lookups, missing kanji reports, and more. Sample decks are also provided for Russian.
