FAQ

Questions, answered

Is this actually different from Duolingo?

Duolingo optimizes for streaks and mascots. We optimize for the person who has an IELTS, Goethe, or JLPT date on the calendar and needs real feedback on their writing and speaking — not another matching-pairs game.

Which exams can I prepare for?

English: IELTS, TOEFL, Cambridge, Business English. German: Goethe A1–C2. Japanese: JLPT N5–N1. Every mock exam is AI-generated and AI-graded — reading, listening, writing and speaking, timed.

How does the AI feedback work?

Every writing and speaking submission is scored against real exam criteria — task completion, grammar, vocabulary range, coherence — with specific corrections, not just a number.

Do I need to speak into a microphone?

It's the fastest way to get pronunciation and fluency scores, but every speaking exercise also accepts typed text if your browser or setup doesn't support voice input.

Can I learn more than one language at once?

Yes — switch between English, German and Japanese from the same account, each with its own level, progress, and mock exam history.
