句式 - Chinese Sentence Patterns

You know hundreds of Chinese words. So why does forming a sentence still feel impossible?

Most apps hand you flashcards and hope grammar sorts itself out. It doesn't. You end up with a head full of vocabulary and no idea how to string it into something you'd actually say.

DouDou Chinese (句式) fixes the real bottleneck: sentence patterns, not word lists. Learn the 100 structures that natural Mandarin conversation is actually built on, then build your own sentences with each one — with instant AI feedback the moment you get it wrong, so mistakes never turn into habits.

HOW IT WORKS • Learn a pattern in context, not in isolation • Apply it immediately by building real sentences • Get instant AI feedback and fix mistakes on the spot • Review with FSRS spaced repetition — timed to hit right before you'd forget, so nothing you learn quietly slips away

No signup, no setup. Open the app and you're already practicing.

WHY IT'S DIFFERENT Vocabulary apps make you feel like you're learning. Sentence patterns make you able to speak. That's the difference between recognizing "你好吗" on a flashcard and actually holding a conversation.
