Powerful, intelligent flash cards

Damien Elmes

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.

Optional LaTeX support is provided by the TeX Live Flatpak extension org.freedesktop.Sdk.Extension.texlive.

What's Changed

New Installer

This release replaces the terminal-based launcher introduced in 25.07 with a more standard installation process:

Anki no longer shows a terminal on installation/update.
Installation no longer requires network access.
Updates can be installed using _Tools>Check For Updates_.
A standard MSI installer is provided for Windows.
A Windows ARM64 build is available.
The macOS builds require macOS 13 or later.
The Linux x86_64 build requires glibc 2.35+.
The Linux aarch64 build requires glibc 2.39+.
The minimum supported Python version is now 3.10 (The official builds still ship Python 3.13).
Qt has been updated to 6.11

_Note_: The _Tools>Upgrade/Downgrade_ option in 25.07+ cannot be used to upgrade to this version due to packaging changes.
