Everything it does
A study tool that grows with you, from the first HSK words through advanced reading.
-
Spaced repetition that tracks two skills
Each word carries separate intervals for recognising the meaning and recalling the pronunciation. Knowing what 朋友 means but blanking on péngyou schedules them differently, so you drill the half you actually missed.
-
HSK 1–9 vocabulary, ready to study
More than 10,900 HSK 3.0 entries with pinyin, traditional forms and English definitions, organised into nine manageable learning stages. The official combined HSK 7–9 advanced band is clearly divided into an OpenChinese progression for study.
-
Graded readers that reinforce as you go
Forty-five original stories and 135 chapters—five sequenced stories at every HSK stage—with characters, goals, conflict and resolution. Each scene stays within a controlled vocabulary while using a few clearly glossed stretch words when the story needs them. Tap any word for its meaning, toggle pinyin when you are stuck, or listen to the complete chapter in Mandarin. Finishing a chapter moves its vocabulary into your dictionary.
-
A dictionary of everything you have met
Every word you have studied or read, with how well you know it, when you last saw it and which level it came from. Search in English, pinyin or characters — pengyou, péngyou and 朋友 all find the same entry.
-
Say it out loud
Speak a word and see what the browser heard against the characters on the card. It is a quick sanity check on your pronunciation, not a tone grader, and it never affects your review schedule.
-
Progress worth looking at
Study streak, accuracy split by meaning versus pronunciation, a two-week forecast of what is coming due, and the words that keep tripping you up. The dashboard tells you what to do next rather than just what you did.
What it deliberately does not do
- Grade your tones. The pronunciation check reports the word the browser recognised. That catches a wrong syllable, not a second tone read as a third.
- Teach grammar. There are no drills or explanations. It is vocabulary, reading and recall.
- Gamify. No streaks-as-guilt, no leaderboards, no notifications begging you back.
