The teaching is done by a person. Credits pay for the machine work behind it — generating exercises, checking answers, synthesising audio, listening to your pronunciation.
There is nothing to buy yet — the whole platform, AI features included, is free while we are still small. Paid plans will appear here, and we will say so before anything changes.
Read a page aloud and see which sounds came out differently from the ones you were aiming for. No score, no level.
Exercises are checked and explained the moment you finish, so your teacher spends the lesson teaching instead of marking.
Visual analytics to see how your vocabulary and grammar improve over time.
