One app.
Every language.
Every conversation.
The OneLingo turns any conversation into one you can both understand — speak naturally, hear the reply instantly, in a voice that can even be your own.
This is what talking to the whole world looks like.
No more switching between a translator for text messages, a separate app for voice notes, a phrasebook for travel, and an interpreter you'd have to book in advance. Just open The OneLingo and talk — in your language, to anyone in theirs, in real time.
The OneLingo is the only one you'll need.
Talk. That's the whole instruction manual.
No phrasebooks, no typing, no waiting for a stiff, word-for-word readout.
Speak, naturally
Talk the way you already talk. The OneLingo auto-detects your language — no menus to dig through mid-sentence.
Understood, instantly
Translation streams in real time — on Plus, it starts speaking the reply before your sentence has even finished generating.
Answered, in a real voice
Hear it back naturally — or in your own cloned voice. Then the mic flips: their reply translates back to you, automatically.
Everything a real conversation needs. Nothing it doesn't.
It still sounds like you.
Clone your own voice once. From then on, every translation you speak comes back out sounding like you said it — not a call-center voice reading your words for you.
Conversation Mode
Two people, two languages, one flow — the mic swaps direction automatically after each reply.
45+ languages, done right
Including native-script accuracy for 10 Indian languages and right-to-left scripts — not just the easy ones.
Three ways to translate
Start free. Go streaming for near-zero lag. Live, continuous interpretation is coming next.
Private by design
Conversations auto-delete after 90 days. Delete your account and everything in it, any time, in-app.
However you say it, we've got it.
From Spanish to Swahili, Mandarin to Malayalam — 45+ languages, with real engineering behind the ones that usually get left behind.
Built on AI that's already proven itself.
We didn't train our own shaky speech model — we built on the ones already trusted for real speech, translation, and voice.
Good to know
What exactly is The OneLingo?
A mobile app for real, spoken conversations across languages. You speak, it detects your language and translates in real time, then speaks the reply back — in a natural voice, or your own cloned one — and automatically flips direction for the other person.
Which languages does it support?
45+ languages and counting, including dedicated accuracy work on Indian languages and right-to-left scripts like Arabic, Hebrew, and Persian — not just the handful most translators stop at.
Is my conversation private?
Yes. Conversations and their audio auto-delete after 90 days, and you can permanently delete your account and every trace of your data at any time, right from the app.
