OneAccord or Koine for translating a church service?
Both put translated voice and captions on the congregation's own phones, in the browser, from a QR code. OneAccord is made only for churches by church interpreters, and lets a person correct the transcript before it is translated. Koine covers more languages, publishes more hours for less money, and shows Scripture in each listener's own Bible. If you want a human checking every sentence, OneAccord has the tool for it; if you want to start free and price it yourself, Koine does.
What each one publishes.
Every figure about OneAccord below is what OneAccord states on its own homepage and its blog post on translation accuracy, checked on 31 October 2026. A dash means we could not find it published, not that it does not exist. Prices change; the sources are linked under the table.
| What | OneAccord | Koine |
|---|---|---|
| What it is | Live AI translation for churches, including multi-site churches, "Built by church interpreters". | Live translation for any room — churches, conferences, schools and public meetings. One audio feed becomes translated voice and live captions on every listener's phone. |
| How listeners join | A QR code, in the phone's browser, with no app or download. | A QR code or a link, in the browser, with no app and no account. A listener app is optional, for notes and replay. |
| Languages | "50+", with about 60 listed. Text and spoken voice. | 132 languages, all with translated voice and captions. Up to 3 at once on Lite and Standard, 5 on the free Sunday, 8 on Pro, up to 20 per room on Campus. |
| Price | From USD 150 a month for 5 hours, "typically enough for 1 service/week". No setup fee. Other plans are quoted on languages, hours and users. | Lite USD 96 a month for 12 language-hours, Standard USD 169 for 24, Pro USD 399 for 70. Or USD 10 per language-hour with no subscription; bought hours never expire. Never per listener. |
| Free start | Free trial credits; the amount is not published. | A free Sunday: one service of up to 3 hours in up to 5 languages, sized for 25 listeners, with no card. Plus a 15-minute test any time. |
| A person in the loop | Moderation mode: someone corrects the transcript before it is translated. OneAccord says this is how transcription reaches 100%. | Bible references are approved at the booth before they show. An interpreter you bring can voice a language, with the AI as backup. |
| Scripture | AI "trained on Biblical terms". A feature for showing verses is not published. | BibleSense: a spoken reference appears in each listener's own published Bible translation. |
| Screens and control | Captions in ProPresenter and OBS; control from Bitfocus Companion and Stream Deck; several sessions labelled by campus. | Captions in ProPresenter, EasyWorship, OBS or vMix, or the desktop overlay over PowerPoint and Keynote. Campus runs up to 10 rooms at once. |
| Afterwards | Downloadable transcripts in the original and translated languages. | A translated transcript per language, listeners' highlights and notes, and a permanent organization page with followers. Recording is a separate switch, off by default. |
| Delay, as published | Written translation in under a second, with audio "soon after". | No measured average published. Translated voice runs a few seconds behind the speaker and varies by language. |
| Where it wins | Church specialists: Moderation mode, a dedicated sound technician, Stream Deck control and campus-labelled sessions. | More languages, more hours for less, a free Sunday with no card, Scripture in each listener's Bible, and rooms beyond the church. |

When OneAccord is the better choice
When you want a person to check the words before anyone hears them. OneAccord's Moderation mode lets a volunteer correct the transcript as the sermon runs, before it is translated. That is the closest an AI service comes to an interpreter's judgement, and Koine has no equivalent for the sermon text. OneAccord is also candid about the limits: it says it does not claim 99% translation accuracy, and that its voices will not match a human's cadence.
The second reason is the people behind it. OneAccord was built by church interpreters, offers a dedicated sound technician, and fits the way a production team already works, with Stream Deck and Bitfocus Companion control and sessions labelled per campus.
When Koine is
When you want to price it yourself and start free. OneAccord publishes one figure, from USD 150 a month for 5 hours, and quotes the rest. Koine's Lite plan is USD 96 a month for 12 language-hours, and a church that only needs translation now and then can buy hours at USD 10 each with no subscription. OneAccord's page does not say whether its 5 hours count per language; if they do, two languages for one weekly service use them up in about two Sundays.
The second reason is the congregation. Koine covers 132 languages with voice against OneAccord's 50+, and a visitor whose language is rare is more likely to find it. BibleSense puts a spoken reference into each listener's own published Bible, so a Ukrainian visitor reads the verse in a Ukrainian Bible rather than in a machine translation of the preacher's.
Third, the rest of the week. The same Koine account runs a conference, a parent evening or a council meeting, and Koine Station handles two-way conversations at a welcome desk.
What the table cannot show
Both are machine translation, and neither of us will tell you whose is better. The honest test is one Sunday with your own preacher and someone bilingual in the pews. Neither replaces a qualified interpreter for pastoral conversations with medical, legal or contractual consequences.
Common questions.
What does OneAccord cost?
OneAccord publishes a starting price of USD 150 a month for 5 hours, which it says is typically enough for one service a week, with no setup fee. Other plans are quoted on languages, hours and users. Checked 31 October 2026.
Is Koine cheaper than OneAccord?
On the published figures, yes. Koine's Lite plan is USD 96 a month for 12 language-hours, against OneAccord's USD 150 for 5 hours. Koine also sells hours at USD 10 per language-hour with no subscription, and starts with a free Sunday.
Can a person correct the translation?
OneAccord's Moderation mode lets someone correct the transcript before it is translated. Koine does not offer that for the sermon text; Bible references are approved at the booth before they appear, and an interpreter you bring can voice a language with the AI as backup.
Do listeners need an app?
Not with either. Both work in the phone's browser from a QR code. Koine's listener app is optional, for notes and replay.
Does either show captions on the church screen?
Yes. OneAccord names ProPresenter and OBS. Koine works as a browser source in ProPresenter, EasyWorship, OBS and vMix, or as a desktop overlay over PowerPoint and Keynote.
