Built for the operator

Everything the room needs, without browser-window juggling.

Keep control on the booth computer while the audience sees only the output intended for them.

Operator console

Start the session, watch audio and language status, and manage what listeners receive from one guided view.

Projector output

Open a separate, audience-safe display for translated captions, Scripture and stage content.

Presentation overlay

Float translated captions over ProPresenter, PowerPoint or the presentation tool already on the computer.

A presentation screen with translated captions positioned as an overlay.
One computer, separate views

The operator keeps control. The audience sees the finished result.

The booth window stays private while projector and overlay windows carry only the translated content meant for the room.

  • Move the audience view to a second screen without exposing controls
  • Keep captions visible above existing presentation software
  • Return to the browser console whenever an install is not practical
Questions

Booth app questions.

Do listeners need the booth app?

No. Only the operator uses the booth app. Listeners scan the room code and join on their own phones, with no app or account required.

Can I still run Koine in a browser?

Yes. The browser console remains available for any computer. Install the booth app when you want dedicated projector and floating overlay windows.

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.

When will the Windows app be available?

The Windows app is planned for Microsoft Store. The page will show an active Store button only after verification and release testing are complete.

Need the listener app?

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