Kaleo vs Voco
Kaleo AI vs Voco
Two church-focused tools with different operator requirements, plan limits, and published integrations.
Prices and features verified 2026-07-21 — source
Voco and Kaleo AI are both church-focused live translation tools. Kaleo publishes church-vocabulary positioning, while Voco provides a configurable glossary and word-boost system. Kaleo's public setup guidance requires Chrome on the operator computer; that does not establish an attendee-browser restriction. Verify current integrations and plan terms directly with the vendor.

Where Voco wins
Operator requirements are explicit
Voco supports modern operator browsers. Kaleo's reviewed technical requirements specify Chrome for the operator computer, while its attendee FAQ says captions work on any device. Do not confuse the operator requirement with an attendee-browser restriction.
OBS and ProPresenter included
Voco documents native OBS and ProPresenter outputs on its £12/week Church plan. Kaleo's reviewed public page did not publish equivalent integrations; verify with Kaleo rather than treating omission as proof they are unavailable.
WiFi backfill — no lost sentences
Voco auto-reconnects and backfills missed audio when WiFi drops. Kaleo AI's offline behaviour isn't documented — in older church buildings with unreliable connections, this gap can mean congregants miss significant portions of the sermon.
Flexible billing intervals and a 7-day trial
Voco offers weekly, monthly, and annual billing plus a 7-day trial with no card. The trial is intended for setup, rehearsal, and one normal Sunday test. Verify Kaleo's current pricing and trial terms directly with the vendor.
Where Kaleo wins
An honest comparison means showing both sides.
Deeply theological AI training
Kaleo AI's model is custom-trained on theological vocabulary — it correctly handles words like Deuteronomy, Doxology, Propitiation, Sanctification, Imago Dei, and Elohim without any glossary setup. Voco's word-boost system is configurable, but requires you to add terms manually. Kaleo's approach is pre-built and deeper for common theological language.
150+ output languages on Unlimited plan
Kaleo's Unlimited plan ($149/month) covers 150+ output languages. Voco currently offers 157+ attendee translation languages and publishes 61+ spoken-input languages. Kaleo's reviewed page did not expose its complete spoken-input list, so verify your preacher's language before committing.
Sunday support
Kaleo explicitly promises support 'all week, including Sundays' — the moment when something going wrong actually matters most.
Pricing comparison
Voco: £6/week (Starter, 1 service and 1–2 language groups) · £12/week (Church, multiple services, all 155+ languages, OBS/ProPresenter) · £22/week (Pro, unlimited live hours and Signal API). Kaleo AI: $24/month Starter (5 hrs, 2 output languages) · $49/month Pro (10 hrs, 4 output languages) · $149/month Unlimited (unlimited hrs, 150+ languages). Important: 150+ output languages on Kaleo requires the $149/month plan. *(Verified July 2026 — confirm current pricing on each provider's site.)*
Frequently asked questions
Does Kaleo AI work on iPhone (Safari)?
Kaleo says attendees can view captions on any device. Its Chrome requirement applies to the operator computer, not the attendee captioning interface; translated audio uses Kaleo's mobile app.
Does Kaleo AI integrate with OBS or ProPresenter?
Kaleo's reviewed public page did not advertise OBS or ProPresenter. That is not proof the integrations are unavailable, so verify with Kaleo. Voco documents both on its Church plan.
How does Kaleo AI's theological training compare to Voco's glossary?
Kaleo AI is custom-trained on theological vocabulary — words like Deuteronomy, Propitiation, and Sanctification are handled by the model itself. Voco's word-boost system lets you add your church's specific terms, names, and passages. Kaleo's approach works without setup; Voco's is more configurable to your specific congregation.
How much does Kaleo AI cost for 150+ languages?
Kaleo AI's 150+ language support is only available on the Unlimited plan at $149/month. The Starter ($24/month) and Pro ($49/month) plans are capped at 2 and 4 output languages respectively. Voco Church at £12/week or £48/month includes all 155+ languages with no cap.
