About Anki

Anki is a program which makes remembering things easy. Because it's a lot more efficient than traditional study methods, you can either greatly decrease your time spent studying, or greatly increase the amount you learn.

Anyone who needs to remember things in their daily life can benefit from Anki. Since it is content-agnostic and supports images, audio, videos and scientific markup (via LaTeX), the possibilities are endless.
For example:

  • Learning a language
  • Studying for medical and law exams
  • Memorizing people's names and faces
  • Brushing up on geography
  • Mastering long poems
  • Even practicing guitar chords!

Features

Synchronization
Use the free AnkiWeb synchronization service to keep your cards in sync across multiple devices.

Flexibility
From card layout to review timing, Anki has a wealth of options for you to customize.

Media-Rich
Embed audio clips, images, videos and scientific markup on your cards, with precise control over how it's shown.

Optimized
Anki will handle decks of 100,000+ cards with no problems.

Fully Extensible
There are a large number of add-ons available.

Open Source
Because the code and storage format is open, your important data is safe.

"The single biggest change that Anki brings about is that it means memory is no longer a haphazard event, to be left to chance. Rather, it guarantees I will remember something, with minimal effort. That is, Anki makes memory a choice."

Michael A. Nielsen, "Augmenting Long-term Memory"

"No other application [...] comes remotely close to Anki in terms of the number and power of features, flexibility in study, or implementation of spaced repetition."

K. M. Lawson, "Anki All the Way"

"I've been using Anki for two years now, and I just wanted to thank you personally for contributing to the single most obvious improvement in my quality of life. I'm not being hyperbolic: consistent use of Anki has opened more doors for me intellectually than I could have imagined two years ago. And being a poor student, I'll be forever grateful that you've provided this software open-source and free of charge."

Anki 2.0

Anki 2.0 is the previous stable release. It is no longer being updated, and does not work well with high resolution displays, but it currently has a larger selection of add-ons available. Your card data is compatible between the two versions.

Not sure which 2.0.52 version to pick? Run 'uname -a' in a terminal and look for x86_64 - if you see it, you want the 64 bit build.

Installation

These packages require an Intel or AMD machine - they will not work on other architectures like ARM.

Once downloaded, the following commands in a terminal window will install it system-wide. The $ is the prompt character, and shouldn't be typed in. Make sure what you're entering in matches the file you downloaded. 

$ tar xjf Downloads/anki-2.1.5-amd64.tar.bz2
$ cd anki-2.1.5
$ sudo make install

Upgrading

If you were running Anki from a .deb/.rpm/etc in the past, please make sure to remove the system version before installing the package provided here.

If you're upgrading from a previous package, simply repeat the installation steps to upgrade to the latest version. Your user data will be preserved.

Notes

Some Linux distributions include Anki in their repositories. We've seen many users experience problems with these distributed versions, due to them being out of date or missing appropriate libraries. For this reason, the compiled package above is recommended over using the version of Anki bundled with your Linux distribution.

Gnome users: to get GTK themes working, please see this page.

Source code

If you wish to build Anki yourself, you will need to ensure you have the required dependencies installed, and you may not be able to run from source on the latest Linux distributions, as a number have stopped shipping a library Anki depends on.

We are not able to provide any support for issues you may encounter when running from source - if in doubt please use the compiled package instead.

iPhone/iPad/iPod Touch

Get AnkiMobile

AnkiMobile is a paid companion to the free computer program, for use on Apple devices. By purchasing the app, you help to support Anki's future development.

If you can't afford the app, you can still use AnkiWeb.

Android Devices

Get AnkiDroid

AnkiDroid is written by a separate group of people. As it was based off the free desktop code I make available, the AnkiDroid developers decided to make the Android version free as well.
