KUDO or Koine for a multilingual meeting?
KUDO sells two things side by side: an AI speech translator its own pages put at 70 or more languages with an average delay of 4.1 seconds, and a bench of 12,000 human interpreters covering 200 spoken and sign languages, bookable two hours ahead. Nothing is priced publicly; events are quoted hourly with unlimited languages per hour, and a venue can buy an annual licence per room. Koine has no interpreters and no sign language, publishes USD 10 per language-hour and plans from USD 96 a month, and puts translated voice on the listener's own phone about 1.5 seconds behind the speaker. The deciding difference is whether you need people in the booth or a price you can read off a page.
What each one publishes.
Every figure about KUDO below is what KUDO states on its own site — the plans and features page, the live events page and the houses-of-worship page — checked on 17 September 2026. A dash means we could not find it advertised, not that it does not exist. The sources are linked under the table.
| What | KUDO | Koine |
|---|---|---|
| What it is | KUDO Inc., of New York, Geneva and San Francisco, sells "live-translated speech and captions in 200 languages" for events and permanent venue installations, powered either by the KUDO AI Speech Translator or by booked human interpreters. The AI side is "One-way communication only". | One audio feed from the room — a microphone, a soundboard line or a livestream link — becomes translated voice and live captions on every listener's own phone, in the browser. Machine translation only. |
| How attendees receive it | "Attendees scan or click to access the KUDO interface on their devices (no downloads needed)... plug in headphones to hear the translated audio or simply read the subtitles." Browser-based, "off WIFI or 4G, using a bandwidth of 10-20 Kb/second"; iOS and Android apps are listed too. In a room, KUDO asks for a laptop and a USB audio interface in each room. | A QR code or a link, in the phone's own browser, as voice or captions. No app, no account, no receivers. The room needs one audio feed into the web console or the Koine Booth app on macOS or Windows. |
| Languages | "KUDO AI... Real-time, AI-translated caption and audio in 70+ languages, including dialects." Their language table is headed "77 languages across Audio & Captions and Captions-Only modes in KUDO AI" and marks each language as one or the other. With human interpreters: "200 multi-way spoken and sign languages." | 70 languages. 57 arrive as translated voice and captions, 7 more as captions only while their voices are tuned. Up to 3 in one session on Lite and Standard, 8 on Pro. No signed interpretation. |
| Delay, as published | "A Patented speech-to-speech translation process, with an average latency (delay) of 4.1 seconds." | About 1.5 seconds behind the speaker for translated voice. |
| Price | None published, and no currency stated. Three routes: a Marketplace with "no annual subscription" for "online meetings and events only"; Pay As You Go for a "single, one-off event"; and an Annual Plan "from 50 hours per year", the last two by Contact Sales. Events use an "hourly pricing model" with "unlimited languages per hour". Venues are offered an "annual license per room... unlimited usage... in every language", with "20% discount on multiple rooms". No free trial is advertised. | USD 10 per language-hour for a one-off event. Plans: Free, Lite USD 96, Standard USD 169, Pro USD 399 a month, also in NOK, SEK and EUR, with annual billing saving two months. Above roughly 150 language-hours, quoted. |
| Listeners | "Unlimited attendees (to platform capacity)" on all three plans, with a stated ceiling of "up to 3,000 users per language, per meeting or event". No per-seat price is published. | Each language is translated once and shared by everyone who selects it, so the bill follows languages and hours, not heads. The plans cap the room instead: 25, 75, 400, unlimited on Pro. |
| Human interpreters | Yes. "12,000 interpreters available on-demand" across "200+ spoken and sign languages", with subject matter expertise, confidentiality contracts, "2 hour lead time for interpreter bookings" and 24/7 coverage, plus the option to bring your own. | None. Koine does not supply or book interpreters, offers no signed interpretation, and does not replace a qualified interpreter for medical, legal or contractual conversations. |
| Afterwards | "Download meeting or event recordings as individual files in all languages. Transcripts refer to automatically generated subtitles available within the meeting recording, using VLC Media Player or QuickTime only." Meeting reports and analytics are also listed. | A translated transcript per language, as text, and a recording only if it is switched on, which it is not by default. Highlights and notes, a permanent organization page, and questions answered from the transcript. |
| Screens and platforms | KUDO Platform, Microsoft Teams, Zoom, Webex, Hopin, ON24, Bizzabo, Eventmobi, Hubilo and GlobalMeet, plus a "live streaming feature for view/listen-only mode or via weblink". ProPresenter, OBS and vMix are not named on the pages we checked. | Captions on the room screen through ProPresenter, EasyWorship, OBS or vMix as a browser source, or the desktop overlay with PowerPoint and Keynote. Remote listeners join the same link at no extra cost. |
| Where the data goes | "Privacy & InfoSec: 100% GDPR compliant; ISO 27001; SOC 2 Type 1/Type 2." Data location, EU hosting and a retention period are not advertised. | Live audio is relayed through Amsterdam; accounts, session metadata and join pages are in Stockholm. OpenAI's speech and translation runs outside the EU today, with EU processing scheduled. Set retention to temporary and no transcript line is written to the database. |
| Where it wins | People. 12,000 interpreters on demand across 200 spoken and sign languages, bookable two hours ahead, around the clock. Plus unlimited languages per hour, an annual per-room licence for venues, 3,000 listeners per language and ten event platforms. | A price you can work out before you call, per language-hour and never per listener. Voice about 1.5 seconds behind. A transcript per language as text rather than subtitles inside a video. EU relay and EU account storage, published. |

When KUDO is the better choice
The headline number on KUDO's site, 200 languages, is the human bench rather than the software: 12,000 interpreters on demand across 200 spoken and sign languages, with subject matter expertise, confidentiality contracts, a two-hour lead time and 24/7 coverage. If your meeting needs an accountable human — a general meeting, a hearing, a negotiation, anything a machine should not be trusted with — that is what you are buying, and Koine does not sell it. Sign language matters on its own here: a deaf attendee is not served by translated audio, and signed interpretation is something KUDO offers and Koine does not.
The second reason is the shape of the price above a few languages. KUDO's event model is hourly with "unlimited languages per hour", and its venue offer is an "annual license per room" with "unlimited usage of speech translation and caption in every language" and 20% off additional rooms. Koine charges per language per hour, so a six-hour day in ten languages is 60 language-hours, USD 600 on our published rate, and the same day in twenty languages is USD 1,200. A flat hourly or per-room licence stops counting languages altogether, which plainly suits a venue running many of them every week.
Third, capacity and connections. KUDO states 3,000 listeners per language per event, against our plan ceilings, which are unlimited only on Pro. It names ten platforms, including Teams, Zoom, Webex, Hopin and ON24, and publishes a browser bandwidth figure of 10 to 20 Kb per second, the sort of number that decides whether a hall full of phones works. It holds GDPR compliance, ISO 27001 and SOC 2 Type 1 and Type 2, and publishes named church installations in the United States.
When Koine is
The first reason is that KUDO publishes no prices at all — not for the Marketplace, not for Pay As You Go, not for the annual plan, not for the per-room worship licence, not even a currency. Every route is Contact Sales. Koine's numbers are on the pricing page: USD 10 per language-hour for a one-off event, or plans at USD 96, 169 and 399 a month, in dollars, kroner and euros. For a church, a school or a public body that must put a figure in a budget before it may request a quote, that alone decides it.
The second is delay. KUDO publishes an average of 4.1 seconds; Koine's translated voice is typically about 1.5 seconds behind the speaker. Four seconds is roughly a sentence, so a listener hears one sentence translated while watching the speaker begin the next. In a panel discussion that is unremarkable; in a service with responses, or a lesson where a teacher asks the room a question, it is more noticeable.
The third is what you have afterwards. KUDO's transcripts are "automatically generated subtitles available within the meeting recording, using VLC Media Player or QuickTime only". Koine produces a translated transcript per language as text, which is what you need in order to quote a passage, publish a summary or search last month's meetings. A recording exists only if somebody switched it on.
The fourth is two-way. KUDO says its AI is "One-way communication only", and answers its own question about two-way conversations with "No - not yet". Koine's room sessions are one-way in the same sense, but the same account also runs Koine Station, a tablet paired to one room that handles a conversation across a table, two people taking turns in two languages. The room set-up is a wash, though: KUDO asks for a laptop and a USB audio interface in each room, and Koine asks for one machine and a way into the room's audio.
What the table cannot show
Both AI sides are machine translation and we make no claim about whose is better. The 4.1-second and 1.5-second figures are each vendor's own, are not measured the same way, and nobody checks them. The test that settles it is ten minutes of your own speaker, in your own hall, on both.
Because KUDO publishes no prices, the price row is a shape rather than a number, and our arithmetic above only tells you what our side costs. A per-room annual licence with unlimited languages could come in below a per-language-hour bill for a busy venue, or well above it for a church running one service a week in two languages. KUDO also does not advertise where its data is stored, whether EU hosting is available, or how long anything is kept; we have written "not advertised" rather than guessing, and for a European public body those are the first three questions to ask.
Finally, the human line. An interpreter is not a faster machine; they carry professional accountability and confidentiality obligations, and they can ask a speaker to repeat a sentence. Koine exists for the events that could never have booked one. Where the law or the stakes require a qualified interpreter, hire one — the comparison with an interpreter sets out where that line falls, and Interprefy is the other vendor here with a bench of them.
Common questions.
Does KUDO's 200 languages mean the AI does 200 languages?
No. KUDO's own pages split the two: the AI speech translator is "70+ languages", and its language table is headed "77 languages across Audio & Captions and Captions-Only modes", with each language marked as one or the other. The 200 figure is the human interpreter bench. Koine publishes 70 languages, of which 57 come with translated voice.
What does KUDO cost?
KUDO publishes no prices and no currency. Its Marketplace has no annual subscription and is for online meetings and events only; Pay As You Go and the annual plan, from 50 hours a year, both route to Contact Sales. Events use an hourly model with unlimited languages per hour, and venues are offered an annual licence per room with 20% off additional rooms.
How much delay should I expect?
KUDO publishes "an average latency (delay) of 4.1 seconds" for its patented speech-to-speech process. Koine's translated voice is typically about 1.5 seconds behind the speaker. Both numbers come from the vendor that benefits from them, they are not measured the same way, and neither is audited, so test in your own hall.
Can either one handle a two-way conversation?
KUDO says its AI is "One-way communication only" and answers its own question about two-way conversations with "No - not yet"; for two-way it books interpreters. Koine's room sessions are one-way too, but a Koine Station tablet runs a two-way conversation across a table, in two languages, on a split screen or on each person's own phone.
How many people can listen at once?
KUDO states "unlimited attendees (to platform capacity)" with a ceiling of "up to 3,000 users per language, per meeting or event". Koine caps listeners by plan — 25, 75, 400 and unlimited on Pro — but never charges per listener, because each language is translated once and shared by everyone who selects it.
Isn't translated captioning already built into Teams and Zoom?
For a meeting that already runs in one of them, it is worth checking first. Microsoft documents live translated captions as a meeting and event feature needing Teams Premium and Microsoft Copilot on the organiser's account, with 50 or more spoken languages into 29 translation languages. Zoom documents them in a meeting or webinar on Business Plus and Enterprise tiers or as an add-on, in over 35 languages. Both are captions only, and neither documents a QR code for people sitting in a physical room.
