A highly customizable companion for your Chinese learning journey.
Add your own content, and Wucai turns it into engaging practice games — anytime, anywhere.
In Wucai, everything revolves around lessons — and you're in full control of what goes into them.
Add new words, edit sentences, remove what you don't need — the app adapts instantly.
Import or create a lesson, and practice activities are generated automatically — no setup needed.
Every game is generated automatically from your lesson content. No setup, no configuration — just import a lesson and start playing.
Three techniques working together to make what you learn stick.
Every character is colored by its tone — blue, green, coral, gold. Your brain builds an automatic visual-audio association. Over time, you see the tone before you think about it.
Words move through boxes based on your performance. Get it right — the interval grows. Get it wrong — it comes back sooner. You always focus on what you still need to learn.
Read real Chinese texts with every character colored by tone. Tap any word to reveal pinyin and meaning. Learning in context dramatically improves retention.
Whether you're studying on your own or creating content for a class, Wucai fits your workflow.
