Grammar Patterns

You've memorized 500 flashcards but freeze when someone speaks.
You can read characters but can't write one.
You know the tones but nobody understands you.

The problem isn't you. It's that every app only trains one face of Chinese.

Flashcard apps
Great for recall. Nothing for listening, writing, grammar, or speaking.
One face only
Gamified apps
Fun streaks but shallow. Translate sentences, pick pictures — no real skill depth.
Wide but thin

Solid structure but no spaced repetition. You forget faster than you learn.

The Core Idea

Every item has six faces.
DuōMiàn trains them all.

Each meaning, character, and grammar pattern in DuōMiàn is a cube with six skill faces. You can inspect any item and see exactly where you stand on each dimension. A word isn't "learned" until all six faces are in long-term memory.

意
Recall
See it, know it. Instant meaning recognition.
读
Reading
Sentences, signs, stories. Real-world text.
听
Listening
Understand spoken Chinese at natural speed.
说
Production
Build sentences. Express your own ideas.
声
Phonetics
Tones and pronunciation people understand.
写
Writing
Stroke by stroke, from memory.
Drag the cube or tap a skill to rotate

Tap any item in DuōMiàn to inspect it. You'll see a skill breakdown for that specific word — how strong your recall is, whether you can write it, if you'd recognize it spoken. The app schedules extra reps only for the faces that need work.

Meet Yun 云

Your first Chinese-speaking friend

The hardest part of learning Chinese? Finding someone to practise with who won't lose patience. Yun never does.

Talk to Yun in the Tea House

She knows exactly what you know.

Yun isn't a generic chatbot. She has access to your entire learning state — every word you've mastered, every character you struggle with, every tone you mix up. She uses only vocabulary you've studied, pushes you just past your comfort zone, and never overwhelms you. The sweet spot where real learning happens.

What Yun knows about you

  • Every meaning you've learned
  • Words you often confuse
  • Your weakest skill dimension
  • Tones you consistently miss
  • Grammar you haven't practised
  • Your current HSK level

The Science

Engineered around how memory actually works

DuōMiàn's SM-2 engine models your memory for every card, across every skill. It intercepts each one right before you'd forget.

DuōMiàn intercepts each card right before the drop. Each success pushes the next review further out.

Five stages. Zero wasted reps.

Every meaning moves through a funnel. The SM-2 algorithm tracks each card independently across all six skill faces.

  • New → SeenCharacters introduced with meaning, sound, and stroke animation. No guessing.
  • Seen → LearningCard enters SRS rotation. Initial intervals: 1 day, 3 days, 1 week.
  • Learning → KnownEach correct review extends the interval. Weeks become months.
  • Known → MasteredA card is mastered only when all six faces are in long-term memory — not just meaning, but writing, listening, production, phonetics, and reading.

The result: 20 cards a day, thousands retained.
