Game-changing.”


You can study a language for years and still panic when someone actually speaks to you. That’s because reading, tapping and memorising train recognition — while conversation trains a completely different muscle: pulling words out of your head in real time, under pressure, with someone waiting for your answer.
Björn’s voice mode gives you that practice on demand. Press talk, start speaking, and have a real conversation — about your day, your plans, your obsessions — with an AI tutor that listens, responds naturally, and never gets tired, bored or judgemental.
Robotic audio teaches you to understand robots. Björn uses the world’s highest-quality AI voices — natural pacing, real intonation, native-sounding accents — so the listening skills you build transfer directly to real people on real streets.
You can also listen back and compare your own pronunciation against Björn’s native-sounding voice, closing the gap between what you think you sound like and what you actually sound like.
A good tutor doesn’t interrupt you mid-sentence to lecture about grammar — and neither does Björn. Mistakes get corrected in the flow of conversation, explained when you want the detail, and saved automatically as flashcards so they become tomorrow’s review instead of next year’s bad habit.
Premium includes around 10 hours of voice conversation per month — more real speaking practice than most learners get in a year of classes. Text conversations are unlimited.
No scheduling, no small-talk anxiety, no judgement — speaking practice whenever you have ten minutes.
Train your ear on speech that sounds human, so real-world listening feels familiar instead of terrifying.
Errors are fixed in the moment and turned into flashcards — the fastest feedback loop in language learning.
Listen to your own speech next to Björn’s native-sounding voice and hear exactly what to adjust.
