Home › Booth app

Run the room from one app.

Only the operator needs the app. Listeners use their own phones.

Booth app questions.

Can I run live translation in a browser?

Yes. You can run core live translation in the web console with a microphone or audio link. Koine Booth adds computer-audio capture, external displays, and floating overlays.

Is the Mac app safe to open?

Yes. The universal Mac app is signed with an Apple Developer ID and notarized by Apple for both Apple silicon and Intel Macs.

Is the Windows app safe to install?

Yes. The installer and app are digitally signed by VOIS AI AS through Microsoft Artifact Signing, so Windows can verify the publisher before installation.

iPhone, iPad and Android have their own mobile app page.
