Powerful, intelligent flash cards.
Remembering things just became much easier.
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

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.

Download
2.1.33 is the latest stable release:
Download Anki for 64 bit Windows 7/8/10 (2.1.33-standard)
Download Anki for 32 bit Windows 7/8/10 (2.1.33-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.
2.1.26 was a previous stable release:
Download Anki for 64 bit Windows 7/8/10 (2.1.26-standard)
Download Anki for 32 bit Windows 7/8/10 (2.1.26-alternate)
Some Windows 7 users have reported seeing a "Fatal Error detected: Failed to execute script pyi_rth_multiprocessing" message when starting the latest version. If this happens to you, please use the older 2.1.15 instead.
Older versions and checksums are available on the releases page. If downgrading from a newer version because you use an add-on that hasn't been updated yet, please make sure you use the Downgrade & Quit button first.
Installation
- Save the installer to your desktop or downloads folder.
- Double-click on the installer to run it. If you see an error message, please see below.
- Once Anki is installed, double-click on the new star icon on your desktop to start Anki.
Install problems
"Error opening file for writing"
If closing Anki and Chrome does not help, please try restarting your computer, then running the installer again.
"Error loading Python DLL" or
"The program can't start because api-ms-win.... is missing"
Please make sure your computer has the latest Windows updates installed. If problems persist, please try manually installing this update and then this update.
"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.

Downloads
2.1.33 is the latest stable release:
Download Anki for 2016+ Linux (2.1.33)
The packaged version requires a 64 bit Intel/AMD Linux, and common libraries like libwayland-client. If you are on a different architecture or a barebones Linux distro, you will not be able to use this package.
2.1.26 was a previous stable release:
Download Anki for 2016+ Linux (2.1.26)
If you are on an old Linux distribution, or one that doesn't support systemd, you will need to use the older 2.1.15 version instead.
Older versions and checksums are available on the releases page. If downgrading from a newer version because you use an add-on that hasn't been updated yet, please make sure you use the Downgrade & Quit button first.
Installation
If you do not have 'make' installed, you will need need to install it first - eg on Ubuntu, 'sudo apt install make'
On recent Ubuntu installations, please use 'sudo apt install libxcb-xinerama0' before running Anki.
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-2.1.26-linux-amd64.tar.bz2 $ cd anki-2.1.26-linux-amd64 $ sudo make install
Problems
If Anki won't start, run 'QT_DEBUG_PLUGINS=1 anki' in a terminal to see if any error messages appear. Chances are you are missing a library that Anki requires, and the error message should indicate what is missing. Installing the library via your distro's tools (eg apt-get) should fix the problem.
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
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 latest code is located on GitHub.
Please read README.contributing and README.development for further instructions.
