No lessons, no homework — just real conversations with someone who needs exactly what you can offer. Matched both ways. You only see people whose languages fit yours in both directions, so every conversation has something in it for both of you. Correct each other. Tap any message to suggest a better way to say it. Corrections are unlimited for everyone, on every plan — teaching is the whole point. Translation when you're stuck. Built in, so you don't leave the chat. A reason to come back.
