How it works

Small enough for a volunteer. Solid enough for a full room.

Bring one source

A microphone, a soundboard feed, or a livestream link becomes the source for the room.

Pick languages

Each language is translated once and shared with everyone who selects it — cost follows languages, not crowd.

People listen

Attendees scan a code and listen on their phones, by voice or captions. Recordings and notes can live on afterward.

At the booth

One person runs the whole room.

Start a session, choose languages, and share the code. The operator keeps an eye on the booth while everyone in the room follows along on their own phone.

More than the hour itself

Translation gets people in. Everything else keeps them.

Most translation evaporates when the speaker stops. Koine turns every session into something that lasts — a live broadcast, a growing library, a study copy, and answers.

Live

Voice, captions, and the room's own audio, streamed to every phone — in the room, the overflow, or another country.

Library

Sessions you publish join your page like a podcast feed — recorded, transcribed, and there for followers who missed the day.

Study

Listeners keep notes, photos and highlights pinned to the moment — and can rewind live or replay it all afterwards.

Intelligence

Ask what was said, get a recap, search everything you've heard — answers grounded in the actual session.

Reach people who can't attend See study tools & Intelligence

Where it works

One tool for wherever language gets in the way.

Services for churches, access for classrooms, scale for conferences, and a public record for civic rooms — plus a private translator in your pocket when you need one.

Why a room system

Better than everyone translating for themselves.

Phone translation apps leave every listener fending for their own audio. Koine translates one clean feed, once, for the whole room.

Vs. translator apps

One clean feed, not 200 phone mics

Translates the soundboard feed — no room echo, no crosstalk, no missed sentences
Everyone reads and hears the same translation, in sync with the speaker
Captions on the main screen, approved Bible verses, saved transcripts — run from the booth, not left to chance

Vs. interpreters & receivers

Every language at once, no hardware

An interpreter team often costs $1,000+ per language per day — Koine is $10 per language-hour
No receiver rentals to hand out, collect, and sanitize — everyone listens free on the phone they already have
Languages interpreters can't cover are one tap away — 50+ at once

Even with no translation

The room's own sound, on every phone

Stream the original audio live — hearing assistance without a hearing loop or receivers
The nursery, the lobby, and the overflow room stay on the session with a phone and earbuds
Homebound members hear the service itself, not just a translation of it

The listener app

Listen live. Keep what mattered. Come back next time.

The browser gets people listening immediately. The optional app lets them take notes and photos as it happens, rewind a sentence they missed, return to the session after the room clears — and follow you, so they know when you start again.

Notes and photos in context — write a thought or snap the slide, kept at the right moment
Rewind and replay — slide back during a live session, or revisit it entirely afterwards
Follow the organizers they return to — a notification when you go live, in their language
Ask about what was said — recaps and answers grounded in the session, with Koine Intelligence
Personal tools when needed — private and two-way translation live inside the same app
