Chatlator turns everyday conversations into language practice. Users choose their native language and the language they want to learn, invite a friend, and start chatting — each message is automatically translated into the recipient’s learning language. A built-in AI tutor, “Chati”, adapts to the user’s level with hints, corrections, and encouragement. No flashcards, no drills — just real conversations in the language you want to speak.
