An open source software program that is used as a study tool to help users commit things to memory. Anki allows you to create custom decks of flashcards to use in study sessions. Anki lets you rate how easy or hard each card is and adapts to that ranking system. Cards you have marked as easy would be shown less frequently than those you have rated as hard. Anki supports images, audio, videos and scientific markup via LaTeX, a typesetting system based on the TeX programming language.
