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."

Download Anki

Choose a platform from the left.

Latest Version

Download Anki for 64 bit Windows 7/8/10 (2.1.9-standard)

Download Anki for 32 bit Windows 7/8/10 (2.1.9-alternate)

If in doubt, choose the standard version, as most Windows installations are 64 bit these days. The alternate version uses an older toolkit, which lacks some improvements.

Installation

  1. Save the installer to your desktop or downloads folder.
  2. Double-click on the installer to run it. If you see a "Windows protected your PC" message, please see the section below.
  3. Once Anki is installed, double-click on the new star icon on your desktop to start Anki.

"Windows protected your PC"

When a new Anki version is released, Windows may display a scary-looking message until it has seen enough people using the new version. To be able to proceed with app installation, please use "Run anyway".

Antivirus programs may sometimes also report a false positive.

Upgrading

If upgrading from an Anki version before 2.1.6, or switching from the standard to the alternate version or vice versa, we recommend uninstalling the old version first, which will remove Anki's program data but not delete your card data.

If upgrading from 2.1.6+ and not switching between standard and alternate version, there is no need to uninstall the previous version first.

Older Versions

Anki 2.0 was the previous stable release. No further updates are expected, as the toolkit it was built on has been discontinued. To minimize the risk of bugs and security issues, please consider upgrading to Anki 2.1.

Download Anki for Windows Vista/7/8/10 (2.0.52-standard)

Download Anki for Windows XP/Vista/7/8/10 (2.0.52-alternate)

Latest Version

Download Anki for Mac OS X 10.12+ (2.1.9-standard)

Download Anki for Mac OS X 10.10+ (2.1.9-alternate)

Choose the standard version if your macOS version is up to date, as the alternate version uses an older toolkit which lacks some improvements.

Installation

  1. Save the file to your desktop or downloads folder.
  2. Open it, and drag Anki to your Applications folder or desktop.

Upgrading

Upgrading is as simple as installing the new version over the old version, and your data will be preserved. Simply close Anki if it's currently running, then follow the steps in the Installation section above.

Older Versions

Anki 2.0 was the previous stable release. No further updates are expected, as the toolkit it was built on has been discontinued. To minimize the risk of bugs and security issues, please consider upgrading to Anki 2.1.

Download Anki for Mac OS X 10.8+ (2.0.52-standard)

Download Anki for Mac OS X 10.5+ (2.0.52-alternate)

Latest Version

Download Anki for 2016+ Linux (2.1.9-standard)

Download Anki for older Linux (2.1.9-alternate)

The second option works on some Linux distributions released before 2016 (eg Ubuntu 14.04), but lacks some improvements that the latest toolkit has made.

Both options require a 64 bit Intel/AMD Linux - these packaged versions do not support 32 bit distributions or other architectures like ARM.

Installation

If you do not have 'make' installed, you will need need to install it first - eg on Ubuntu, 'sudo apt install make'

Once downloaded, the following commands in a terminal window will install Anki 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-2.1.9-amd64.tar.bz2
$ cd anki-2.1.9-linux-amd64
$ 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.

Older Versions

Anki 2.0 was the previous stable release. No further updates are expected, as the toolkit it was built on has been discontinued. To minimize the risk of bugs and security issues, please consider upgrading to Anki 2.1.

Source code

You are welcome to run Anki from source, but the source code is provided without any support - when running from source the expectation is that you will ensure all the required dependencies are installed, and address any issues you encounter on your own. If you run into issues and require support, please use the packaged versions we provide instead, as they are built with library versions that are known to be working.

Development

The development branch is located on GitHub.

Please read README.contributing and README.development for further instructions.

Translating Anki

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.
