Anki

Friendly, intelligent flash cards.

Remembering things just became much easier.

With support for text, graphics, video, audio, or scientific markup, Anki makes it easier to learn almost any subject. Anyone who needs to remember things in their daily life can benefit from Anki. Since it is content-agnostic and supports images, audio, videos and scientific markup (via LaTeX), the possibilities are endless.

In addition to using it on your desktop, you can also use it on your iPhone, Android phone, or even your Nintendo DS.
