Speak their language.
Get help in yours.

When I practice Vietnamese, people switch to English. So I built Uyen: an AI conversation partner that stays in your new language and helps you find the words when you get stuck. — Nathan

Why Uyen?

A note from Nathan
Uyen is pronounced Win.
Uyen is named after my wife. She was and is my conversation partner when I practice Vietnamese.
When I try to speak Vietnamese with other people, they usually switch back to English unless I ask them not to. Even then, they rarely help me through mistakes at a pace that works for me.
That is frustrating, and it is why I built this app. Uyen is an AI conversation partner that stays in the language you are learning, helps you find the words, and keeps the talk going.
If something feels wrong or you need help, reach out anytime. We can even jump on a call.
