Lexo
Translate selected text in any application with a single keyboard shortcut — 100% on-device, without sending your data to the internet.
What Lexo does
Instant, private translation everywhere on your Mac.
Global shortcut
Select text anywhere and press ⌃⇧T (Ctrl + Shift + T). The translation appears instantly.
100% local and private
Translation uses Apple's on-device engine. No text is sent to the internet, no API key.
Works in every app
Mail, Safari, Slack, VS Code, PDF… Lexo captures your selection everywhere, without touching your clipboard.
Floating bubble
The result shows in a small, elegant bubble near your cursor, without stealing focus.
Automatic detection
The source language is detected for you. You just pick the target language.
Choose your target language
French by default, with dozens of languages available in the preferences.
Read aloud
Hear the pronunciation of the original and the translation in one click, with macOS premium voices.
Translation history
Your translations are saved locally, ready to search and reuse.
Interface in 40 languages
Lexo's interface is available in 40 languages — every macOS system language — automatically based on your Mac, or your pick in the preferences.
Automatic updates
Lexo updates itself: you always have the latest version, with nothing to reinstall.
Your text never leaves your Mac
Lexo relies on Apple's Translation framework: everything is translated offline, on your machine. No server, no tracking, no account.
