Master Chinese.
SlashHanzi is a Hanzi vocabulary app for HSK and beyond. Memorize characters through multi-pass recall and adaptive review, then use them in AI conversations personalized to what you have learned.
The 4-pass method
Learn a word until it feels natural.
Recognition is only the beginning. Each word travels through four distinct passes, training meaning, characters, and sound from both directions. When an answer slips, the word returns later in the same pass.
02
Pinyin → Hanzi
See the sound
Hear or read the pronunciation, then choose the characters that belong to it.
03
Meaning → Hanzi
Produce it
Start from intent and retrieve the Chinese word you would need in a real moment.
04
Hanzi → Pinyin
Own the sound
Finish by recalling the exact pronunciation and tone from the characters alone.
Learn + review
A daily session that knows what matters next.
SlashHanzi mixes new words with due reviews in one focused session. Overdue and difficult words rise first, while your recall history adjusts what comes next.

Sound, made visible
Fine-tune every sound.
Combine initials, finals, and tones. Listen to native audio and follow the tone contour so pronunciation becomes part of every word you learn.
How do the four passes work?
You move through word-to-meaning, pinyin-to-Hanzi, meaning-to-Hanzi, and Hanzi-to-pinyin recall. A missed word returns at the end of that pass, and mastery requires completing all four.
How does Learn decide what I should review?
Learn combines new words with due reviews. Overdue and harder words come first, while your recall history adjusts their future spacing across 1, 2, 4, 7, 15, 30, and 60-day intervals.
Which HSK vocabulary decks are available?
HSK 1 through HSK 4 decks aligned to the 2025 vocabulary standard are available now. More curated decks will follow.
How is my AI conversation personalized?
SlashHanzi uses your recently mastered vocabulary, broader learned-word pool, current level, and performance to shape a suitable scene, partner, target words, and challenge.
Can I choose my daily pace?
Yes. Choose a daily group target during setup and change it later. SlashHanzi shows the new-to-review mix, estimated study time, and projected finish date.
