Anki: A practical application that can help you assimilate information easier and faster

Whatever the subject matter you need to learn, this typically consists of going through the manuals and/or documentation multiple times in order to memorize as much knowledge as possible. Study cards are one of the most common (and effective) ways to speed up the learning process as well as consolidate new information.

Instead of creating study cards with the pen and paper, you can always use a simpler method that puts your computer to good use, like the one provided by Anki.

Anki is a reliable tool that lets you easily create memorization cards so you can learn whatever content you want, in a faster and more effective manner. The simple interface lets you generate a deck right away and add notes and cards.
These can be various types such as items with some occluded words, basic with optional reversed card and many more. Furthermore you can create your own cards from scratch and customize them during that process.

The application includes a card browser that lets you quickly find, view and edit recently added or studied notes. You can further customize your decks by adjusting the step timing, graduating interval and reviews percentage among others. Anki also can synchronize and backup your card decks so you can access them from any of your devices.
