Virtual teacher lead

The app is teacher-led. Most apps hand you exercises and leave you to it; here a virtual teacher is present on every study screen, opening each task with a short prompt and stepping in where a word list or a bare translation would leave you guessing.

Each course has its own named teacher — 王老师 for Mandarin, and a teacher for every other language — so the voice guiding you stays consistent from the first chapter to the last.

The prompts are authored alongside the course material, so they point at the exact thing that trips learners up on that line, in that chapter.
