Meet your teacher.
I learned Chinese as a second language, then spent a decade teaching it in New Jersey public schools. I built this course from my actual classroom — the same lessons, stories, and games my students loved. Every video is me teaching. Every voice is a real character. This is the course I wish existed when I started learning.

Common questions.
Is this for complete beginners?
Yes. The course starts from zero — no prior Chinese knowledge needed. We begin with tones, basic greetings, and build up from there.
How is this different from Duolingo?
Duolingo uses AI-generated content and gamification. This is a real course from a real teacher — 104 structured lessons with video coaching, stories, and cultural context.
Do I need to know Chinese characters?
No. Every lesson includes characters, pinyin (pronunciation guide), and English. You toggle between them with a tap.
Is this an app I download?
It works instantly in your phone's browser — no app store download needed. You can also add it to your home screen for an app-like experience.
What if I don't like it?
The first 3 phases are completely free. Try them before you spend a dollar. If you buy and aren't satisfied, reach out within 7 days.
Is the $88 a subscription?
No. It's a one-time payment for lifetime access to the full course — all 104 lessons, all updates, forever.
