About

Mintza

You understand the language. You just can't speak it yet. Mintza is a live voice conversation with a bilingual AI teacher. It talks with you about anything you want, out loud, and the moment you get stuck it switches to the language you already speak, then guides you back. No scripts, no fixed lessons, no set path. It feels like a real conversation, not a lesson, with the pauses and rhythm of a real call, and it goes wherever you take it. You lead, it follows. Argue about football. Plan a trip. Talk through a job interview, your day, or nothing at all. Say what you want to talk about, out loud, and the conversation goes there. Or say nothing, and your teacher brings up the things you care about. The moment you lose a word, tangle the grammar, or just go blank, your teacher meets you in the language you already speak, sets you back on your feet, and keeps going. You are never stranded. There is no one else in the room. No face that falls when you stumble, no one waiting for you to be impressive. You get to be bad at it, out loud, as many times as it takes, and no one ever knows. And the practice is yours to run. There is no clock on the screen while you talk: you speak until you forget you're practicing. There are no streaks and no guilt: set your own reminders, your days, your times, or none at all. Mintza won't nag you into coming back. It'll just be here when you do. Tell your teacher about you, in your own words: your name, what you do, the trip you're prepping for, how you like to learn. From the first hello, it's talking to you, not to a stranger. It adapts to you. To your level, from your first words to your fourth language. To what you actually care about: travel, work, food, culture, sports, music. The conversation bends around your life, not a textbook's syllabus. No child learned to speak by memorizing rules. They learned by speaking. Other apps teach you vocabulary and grammar; Mintza is where you finally use it, out loud, in a real back and forth. - A real, open conversation that goes wherever you take it - A bilingual teacher that helps in the language you already speak when you get stuck - No clock on screen, no streaks, no imposed path: you decide when to practice and what to talk about - Reminders you set yourself, your days and your times - Tell your teacher about you, so it talks to you, not a stranger - Adapts to your level and the things you care about - Pick a regional accent, British or Australian English, Madrid or Buenos Aires Spanish, and many more - Any of fifteen languages, in either direction Open the app. Pick the language you speak. Pick the language you're learning. Talk. English, Spanish, Portuguese, French, Italian, German, Greek, Chinese, Russian, Turkish, Swedish, Arabic, Japanese, Korean, Hebrew. Any pair, any direction. At midnight, on your commute, whenever you have ten minutes. After ten minutes you will have spoken more of the language you're learning than in a month of flashcards. When you're ready for more: - Basic: 180 minutes a month - Plus: 360 minutes a month - Pro: 600 minutes a month, about twenty minutes a day That's ten hours of real conversation a month. A private tutor gives you one, for the same money, and you'd have to book it. 20 free minutes, no card. Open the app and have your first real conversation today.
