Kaiku speaks your language natively.
Kaiku isn't translated from Finnish — it's written natively in each language. 31 languages: European, Asian, Arabic, all at the same depth. You choose, Kaiku adjusts.
The same deep experience, in your language
Example: in Estonian Kaiku says "Tere hommikust", not "Hello" or "Good morning". Nuance, politeness forms and cultural references land right.
Every language has its own prompt base — Kaiku's voice, support models and vocabulary are designed natively from the start. You don't drop to a translated-text level.
- 1Greeting with a native idiom — not a translation from Finnish or English.
RTL scripts, full right-to-left support
Arabic and other RTL languages have full support. The whole UI mirrors, text flows right to left, the experience is native.
You don't get half-RTL support where only the text is translated but the layout stays LTR. Kaiku buttons, tab rows and cards all mirror.
Couple space supports two languages side by side
When a couple speaks different languages, each picks their own Kaiku language. The daily question shows in each person's language, and Kaiku's insights arrive natively for each.
You don't have to compromise on a shared language. You speak to each other however you want — Kaiku adjusts to each language separately.

Your language from the first tap
Language choice is at the start of the app and changeable anytime. No premium requirements, no extra fees.
31 languages are part of Kaiku for everyone. You can pick the UI language and Kaiku's communication language separately if you want.
Market prioritisation, not all languages at once
We started with Finnish and English, grew with market prioritisation.
More languages coming — each new language requires native-speaker review, not just a GPT translation. Request a language: team@kaiku.live.
I tried Kaiku in Estonian and was surprised: greetings, politeness forms and even a touch of humour all felt natural. Not a translation-machine feel.
