Sound familiar?
The taxi driver tells you something about the route and you just smile. At the market you end up paying whatever they ask, because haggling in gestures is exhausting.
Your mother-in-law has spoken to you in her language for years, and it all stays stuck in smiles and half-translations. There's a whole relationship waiting right there.
That call with the overseas supplier: you caught 70%, said yes to everything, and now you're just praying the order arrives right.
You put on a talk, a service, a conference — and half the room checks out because they can't understand the speaker. Interpretation booths cost more than the event itself.
Every one of those scenes is playing out this week, somewhere in your life. And the usual way out — "we sort of understood each other" — costs you deals that never close, families that only half-connect, and audiences that never come back. Language shouldn't decide which conversations happen.
The language barrier doesn't fall after three years of classes. It falls the moment you start talking — today.
The solution
Kai isn't a dictionary with a microphone: it's a fluid, back-and-forth conversation in a natural voice. Three modes, three real situations:
Pick the language you want to hear in and you're set: your phone picks up what's being said — in any language, with nothing to configure — and plays it back to your ear, translated, almost instantly. For the trip, the video, the talk you walked into without an interpreter.
You open a room and the other person just scans your QR with their camera — no account, no app, nothing to search for. Each of you speaks your own language on your own phone and hears the other in theirs. A real conversation, not a phone passed back and forth.
You project a QR on the room's screen. Each attendee scans it, picks their language, and hears the speaker translated through their own earbuds, with live captions — no account and nothing to install. And here's what no one else offers: we don't charge per attendee — you pay per active language and by the scale of your event. Within your tier, more listeners never raise the price — half-full or packed, it costs exactly the same.
No hassle

Choose your modeSolo, Conversation, or Conference, depending on the moment. You don't set input languages: the system detects on its own who's speaking what.
Just talk naturallyThe translation flows live, in a natural voice. With earbuds, it reaches only your ear — like a personal interpreter.
The next conversation that matters could be this week.

For organizers
Conferences, churches, seminars, assemblies: the traditional option is interpretation booths at hundreds of dollars an hour and per language. With Kai, you set up translation for your event in 5 minutes:
And of course
No fine print
No mandatory subscription and no automatic charges: you buy credits when you need them, and they never expire. Here's how they're used:
One pass covers 1 language for 70 minutes at your event — fixed price, 20–45% cheaper than paying by the minute. Need 3 languages? 3 passes. On the plans page there's a calculator that tells you exactly which ones you need.
Let's clear up your doubts
No. Kai Live Translate runs entirely in your phone's or computer's browser: you go to livetranslate.kaistrategylab.com, create your account, and you're already translating. Nothing to download or update.
No. In Conversation and Conference the other person just scans your QR code with their camera: they're in right away, pick their language, and that's it — no account, no app, and no page to search for.
The translation arrives about a second behind and with no turns: while you keep talking, the other person is already hearing the translation in a natural voice. It's a fluid conversation, not a walkie-talkie.
It automatically detects more than 70 languages as it listens — no one configures anything — and translates with voice into 13 languages: Spanish, English, Portuguese, French, Italian, German, Chinese, Korean, Hindi, Indonesian, Japanese, Russian, and Vietnamese.
You start free with 20 credits (≈ 10 minutes of translation), no card. After that you buy credits only when you need them: packs from US$9.99 for 60 credits. Solo uses 2 credits per minute and Conversation 4. There's no mandatory subscription and no automatic charges.
Purchased credits never expire. Only the 20 welcome credits expire after 14 days if the account never tops up — they're for trying it out, not for stockpiling.
By card and local payment methods from your country, in a secure checkout run by dLocal (prices are in US dollars). Credit is instant: you pay and your credits show up in your account within seconds.
We don't store the audio or the text of your conversations. We only log usage metadata — date, mode, languages, and duration — so you can see your own usage history.
No: we bill per active language and by the event's scale, never per attendee. An event with up to 100 listeners is the Auditorium tier; with an audience in two languages you'd use 2 Auditorium passes (US$59 each) per 70-minute block — and whether half the room or the whole room shows up, the price doesn't change. The calculator on the plans page tells you exactly what yours will cost.
Yes. A listener can lock the screen or switch apps and the audio keeps playing, like a radio. Whoever is broadcasting (the organizer) does need to keep their device with the screen on, like the event's console.
It's not a replacement for a professional interpreter in legal, critical medical, or high-precision diplomatic settings, it doesn't translate written documents, and it needs an internet connection to work. Its home turf is real everyday conversation: travel, family, business, and events.
