The operator screen: what's said on the left, the translation on the right, as it happens.
The same live translation goes to the big screen, to ProPresenter, and to phones in the pews or at home.

This isn't a meeting tool repurposed for church. It was built for preaching, Scripture and prayer.
60+ spoken languages are detected automatically and captioned into any of ~29 targets. Bilingual services flip direction automatically.
It translates verses as Scripture and keeps names, books and references exactly as the preacher said them.
It catches mis-hears and uncouth expressions before they reach the wall. Strong Scripture language is still translated faithfully.
Optional voice output for headphones or a side room. It can even use the speaker's own voice, with their permission.
Download the translated audio, timed subtitles and a side-by-side transcript afterwards.
It runs on your church's computer. Audio goes only to the providers you choose. We never see it.
Every default was chosen by testing against hours of recorded sermons. Where accuracy and speed pull apart, accuracy wins, and you can adjust the balance.
It waits for a sentence or a natural pause instead of flashing half-phrases that change as you read them.
That's the typical gap from spoken word to screen at the default pace. Slide the Pace bar for quicker pieces or fuller sentences.
A fast check flags lines that were likely misheard, and a stronger model redoes just those, without slowing the rest.
