      The Mnemosyne Project has two aspects:

        * It's a free flash-card tool which optimizes your learning process.
        * It's a research project into the nature of long-term memory.

      We strive to provide a clear, uncluttered piece of software, easy to use
      and to understand for newbies, but still infinitely customisable through
      plugins and scripts for power users.

      ## Efficient learning

      Mnemosyne uses a sophisticated algorithm to schedule the best time for
      a card to come up for review. Difficult cards that you tend to forget
      quickly will be scheduled more often, while Mnemosyne won't waste your
      time on things you remember well.

      ## Memory research

      If you want, anonymous statistics on your learning process can be
      uploaded to a central server for analysis. This data will be valuable to
      study the behaviour of our memory over a very long time period. The
      results will be used to improve the scheduling algorithms behind the
      software even further.
