Why bother?

Low-carbon

Why make tons of web requests every time you need to define a word? Here everything happens offline and the app itself doesn’t use much resources!

Definition pop-up

Highlight some text in any application, press a hotkey, and see a window appear next to your word with all its definitions!

Supports multiple languages

Search across as many dictionaries in as many languages as you can handle! You can even click any word in the definition to jump from one language to another.

Free

Both the app and the dictionaries themselves are completely free!
