[Mnemosyne](http://mnemosyne-proj.org) is an open-source, cross-platform flashcard program that uses a [spaced repetition](https://en.wikipedia.org/wiki/Spaced_repetition "wikipedia:Spaced repetition") algorithm for maximizing learning efficiency.

It is inspired by the proprietary [SuperMemo](http://www.supermemo.com) and comparable to [Anki](/index.php/Anki "Anki"), but with a stronger focus on a minimalist, distraction-free UI and simple but flexible work-flow.

Mnemosyne is written in Python 2 and uses the [Qt](/index.php/Qt "Qt") toolkit.

## Installation

### Installing from AUR

A [mnemosyne](https://aur.archlinux.org/packages/mnemosyne/) package is available in the [Arch User Repository](/index.php/Arch_User_Repository "Arch User Repository").

### Manual Installation

For manual compilation and installation, you can get a tarball from the [official download page](http://www.mnemosyne-proj.org/download-mnemosyne.php) and follow the instructions in the accompanying README file.

### Configuring

Most of the options in Mnemosyne are available directly in the user interface. A few infrequently-used options are accessible through a config file located at `~/.config/mnemosyne/config.py`.

##### Size of mathematical formulae

If you would like to decrease the rendering resolution of mathematical formulae (default 200 dpi, which is rather large on most screens) to better fit with normal text, open the file `~/.config/mnemosyne/config.py` and decrease the number following the -D option in the line that looks like:

```
dvipng = "dvipng -D 200 -T tight tmp.dvi"

```
