About
A story to follow. A voice to find.
A STORY YOU'LL WANT TO FINISH
David moves to Chengdu knowing almost nothing. He meets Xiaoyu and her enormous cat, Baozi. You learn every word as he does, from your first 你好 to a job, a move, a wedding, a baby. Each lesson: listen, answer questions, repeat after the cast, act out the dialog, then say it about yourself.
UNDERSTAND FIRST
Built on comprehensible input: you understand first, through pictures and context, and speech follows. By the time a story begins, you've already met almost every word in it, so you can follow along.
HEAR HOW YOU SOUND
Say a word and your pitch is drawn over the correct tone, measured 100 times a second. Say a sentence and every syllable is checked, its sounds and its tone, with the ones to polish marked in red. Every sound clear, every tone true.
TALK OUT LOUD
Order tea, buy fruit, see the doctor, get through a job interview, or try to get Baozi to move. Each talk has goals and stays within the words you know. Slips get corrected in red pen as you go, and you finish with a teacher's note.
WORDS THAT STAY
Words come back just before you'd forget them, on a modern spaced-repetition schedule. Browse the full HSK 1–9 lists, about 11,000 words, star what you want to keep, and see how well each word has stuck.
PRACTICE YOUR WAY
Pronunciation by HSK level, tones by ear, dictation, word order, fill the gap, word matching and stroke-by-stroke writing. Pro adds a library of hundreds of dialogs, up to advanced.
