What is Mnemosyne?
Mnemosyne (named for the Greek goddess of memory, Mnemosyne) is spaced repetition software developed from 2003 until the present. The software is similar to SuperMemo, commercial software developed by Piotr Wozniak.
Mnemosyne uses an early version of the SuperMemo algorithm, SM-2, with some modifications that deal with early and late repetitions.
Proponents of spaced repetition software claim that by allowing algorithmic scheduling of learning reviews, long-term memorization of items is aided.
Mnemosyne also voluntarily collects data from its users. This data is available from Bienstman upon request or via BitTorrent, and is a research project on long-term memory.
Comments and Reviews
Said about Mnemosyne as an alternative
Very similar in look and function, to Anki. Mnemosyne isn't as customizable, but it's easier on beginners.
Easier to use for beginners. Cram plug-in available out of the box.
