Zui

An AI friend who texts you in English every day — gentle corrections, word-by-word pronunciation scores, and games inside the chat.

A new way to learn English: no lectures, no pressure — just texting with a friend who actually cares what you have to say.

Zui gives you 9 AI friends, each with their own personality and story: Mai your best friend, K-pop fan Linh, office mentor Minh, gamer Tuấn… You chat about real life — ordering coffee, the farmers market, a morning shift, a job interview — and your English improves naturally, exactly the way you'll use it in the real world.

WHY ZUI?

• Gentle corrections: after every message you send, a short note in Vietnamese shows what to fix — no grades, no judgment.

• Tap any word: the meaning, pronunciation, and an example appear right in the conversation, and the word saves itself to your personal notebook.

• Real speaking practice: voice mode scores your pronunciation word by word — including the final sounds Vietnamese speakers tend to drop.

• Learning that feels like play: word-bank puzzles appear right inside the chat, at the moment they matter, on the grammar you need.

• Friendships that grow: the more you talk, the more your AI friends remember about you — and the more stickers you unlock.

• Progress you can see: day streaks, a level estimate, your vocabulary notebook and a mistake journal, all in your profile.

Zui is built for Vietnamese speakers: a Vietnamese interface, grammar explained in Vietnamese, and situations familiar to students, workers, and Vietnamese families living abroad — or anyone in Vietnam who wants to speak with confidence.
