EasyDict

The first open-source translator that is completely open, dictionary data included.

EasyDict is an English–Czech and Czech–English dictionary that works offline on Linux, Windows, macOS and Android, and a website at easydict.jiri.one, where it also runs in the browser as a web app. It contains more than 150,000 translations of the free English–Czech dictionary of the Svobodné slovníky project and also finds Czech words typed in other forms (psa → pes).

Download

The builds of every release are on the releases page:

• Linux – easydict-…-linux-x86_64.tar.gz (or aarch64): unpack it and run easydict. The Flathub package is on its way.
• Android – easydict-…-android.apk, or the smaller …-android-arm64-v8a.apk for most phones. The F-Droid package is on its way.
• Windows – easydict-…-windows-x64.zip: unpack it and run easydict.exe.
• macOS – easydict-…-macos.zip: the app is not notarized, so the first start has to be allowed in System Settings → Privacy & Security.

Tips:

• On Android, select a word in any app and choose Look up in EasyDict from the menu.
• On the desktop, easydict WORD starts with WORD looked up. Bound to a keyboard shortcut, e.g. sh -c 'easydict "$(wl-paste --primary)"', it translates the selected text.

Repository

• data/ – the dictionary data, a continuation of Svobodné slovníky, and the tools that build the app database

History

EasyDict started in 2020 as a desktop app in Python and GTK 3, published on PyPI and Flathub, followed by a GTK 4 and libadwaita rewrite in 2023–2024. Both live on in easydict-gtk. The website went from CherryPy to Django. In 2026 the project moved into this repository, the dictionary data got their new home here after svobodneslovniky.cz went offline, and the app was rewritten in Flutter to run on phones too.
