Mnemosyne software resembles a traditional flash-card program to help you memorise question/answer pairs, but with an important twist: it uses a sophisticated algorithm to schedule the best time for an item to come up for review. Difficult items that you tend to forget quickly will be scheduled more often, while Mnemosyne won’t waste your time on things you remember well.
Each day, the software displays each card that is scheduled for repetition. The user then grades their recollection of the card’s answer on a scale of 0-5. The software then schedules the next repetition of the card in accordance with the user’s rating of that particular card and the database of cards as a whole. This produces an active, rather than passive, review process.
This spaced repetition system is written in Python.
