Press the hotkey
A global shortcut summons the Liquid Glass popup right at your cursor.

See it work

Translate with conventional engines, ask AI for nuance, and hear it spoken — without leaving the popup.
Conventional engines, instantly

¿Me podrías echar una mano?
Could you give me a hand?
The difference
Six steps, or one keystroke
Translation used to mean breaking your concentration. LangBar collapses the whole detour into a reflex.

Questions, answered honestly
The small print, without the spin.
A Mac on macOS 26 (Tahoe) with Apple Silicon. It's a free download as a DMG.
Right-click the app and choose Open. The build isn't notarized yet, so macOS asks once — after that it opens normally.
That's how LangBar reads the text you've selected in other apps. Prefer not to grant it? Just type or paste straight into the popup instead.
In the macOS Keychain — encrypted and never written to disk in plaintext. They're used only to talk to the provider you chose.
Yes. Pick Apple's on-device translation engine and Apple Intelligence for AI, and nothing leaves your Mac.
No. There's no analytics, no account, and no telemetry. There's nothing to opt out of because nothing is collected.
