About this app

Speak every day. Become fluent.

Unlimited conversation in 13 languages, with teachers who correct you in real time and pick up where you left off, class after class.

LEARN BY SPEAKING, FROM DAY ONE
• Talk: choose your language, your teacher and a topic, and start a conversation class at any hour.
• Get corrected: your teacher corrects your pronunciation and grammar as you go, at the level you choose.
• Review: after each class you get a lesson with every correction, a writing prompt, reading and listening suggestions, flashcards and games built from your own mistakes.

13 LANGUAGES
English, Spanish, French, German, Italian, Portuguese, Russian, Japanese, Mandarin Chinese, Korean, Hindi, Czech and Polish.

67 TEACHERS FROM 27 COUNTRIES
Each with their own personality, accent and story. Your level is assessed after every class, so you always know how far you've come.

YOUR TEACHER IS ON WHATSAPP
Eight of our AI teachers are also on WhatsApp. Save the number and practice whenever you have a few minutes, by voice note.

A LEARNING GUIDE, AN ADMINISTRATOR AND A COMMUNITY
Victor's AI avatar is your Learning Guide: he knows your level and your classes and tells you what to practice next. Jane's AI avatar, our Administrator, answers questions about your plan and your account at any hour. Communities let you study together, with leaderboards and challenges.
