Anki is a spaced repetition flashcard program. The software is similar to SuperMemo, a commercial product for the same purpose, and Mnemosyne, another free flashcard program. Anki (暗記) is the Japanese word for "memorizing".
The SM2 algorithm, created for SuperMemo in the late 1980s, forms the basis of the spaced repetition methods employed in the program. Anki's implementation of the algorithm has been modified to allow priorities on cards and to show cards in order of their urgency.
The cards are presented using HTML and may include text, images, sounds, and LaTeX equations. The decks of cards, along with the user's statistics, are stored in the open SQLite format.

[edit] Unique features
[edit] Facts
Compared to other flashcard programs, Anki stores data differently. Within Anki, data is held in two forms: "facts" and "cards". Facts are analogous to database entries and can have an arbitrary number of fields. For example, with respect to learning a language, a fact may have the following fields and example entries:
- Field 1: Expression in target language – "gâteau"
- Field 2: Pronunciation – [sound file with the word "gâteau" pronounced]
- Field 3: Meaning of expression in familiar language – "cake"
This example illustrates a three-sided flashcard, but Anki's model is more general and allows any number of fields to be combined in various cards.
The user can design cards that test the information contained in each fact. One card may have a question (expression) and an answer (pronunciation, meaning).
By keeping the separate cards linked to the same fact, spelling mistakes can be adjusted against all cards at the same time and Anki can ensure that related cards are not shown in too short a spacing.
[edit] Syncing
Anki supports synchronization with a free online server. This allows users to keep decks synchronized across multiple computers, and to study online or on a cell phone.
[edit] Japanese and Chinese reading generation
Anki can automatically fill in the reading of Japanese and Chinese text. Since version 0.9.9.8.2, these features are in separate plug-ins.
[edit] Comparisons
Anki's scheduling algorithm is based on an older version of the SuperMemo algorithm (SM2). The Anki author claims that newer versions of the Supermemo algorithm are more susceptible to incorrect scheduling.[1]
[edit] Mobile Versions
The following Smartphone clients are available[2]:
- AnkiDroid[3] for Android (free)
- AnkiMobile[4] for iPhone, iPod touch or iPad (paid)
- AnkiMini
- AnkiWeb[5] (free online server)
The flashcards and learning progress can be synchronized both ways with Anki using AnkiWeb. With AnkiDroid it is possible to have the flashcards read in several languages using text-to-speech (TTS). If a language does not exist in the Android TTS engine (eg Russian in the Android version Ice Cream Sandwich), a different TTS engine such as SVOX TTS Classic can be used.
