OpenCards is a free award-winning flashcard learning software. The basic idea of OpenCards is to use PowerPoint presentations (*.ppt) or Markdown (*.md) files as flashcard sets.
Thereby, slide-titles are represented as questions and the slide contents as their answers.
Based on state-of-the-art memorization and scheduling algorithms OpenCards will help you to learn any set of flashcards.
- Implements two different learning models:
- A box-based short-term learning procedure, called last-minute learning.
- More sophisticated long-term memorization model based on the principles of active recall and the forgetting model. The latter is implemented as an improved version of the SuperMemo2 algorithm. The SM2 algorithm had been created for SuperMemo in the late 1980s, but still forms the basis of many spaced repetition software applications. OpenCards’s implementation of the algorithm is modified to allow priorities on cards, and to show cards in order of their urgency.
- Flexible flashcard design (vocalization, fast image copy, HTML copy & paste, and Asian language support).
- Support for markdown files as flashcard sets with the following advantages:
- Plain text format which can be version controlled with git.
- Better editing power.
- Allows users to mix documentation with questions and answers. OpenCards will by default just consider section that end with a “?” as flashcards. This can be changed in the preferences (->Advanced).
- Better support for equations (e.g. using MathJax).
- Easier programmatic creation of flashcard sets from content.
- Faster because it works without reading the tough binary .ppt format.
- More web-friendly since markdown can be converted to HTML within the browser.
- Well supported flashcard-file format.
- Good community support.
- Abundant free card-files available from the internet.
