How to use it
Paste a passage and compare its vocabulary with the words saved in this browser. Use the counts to decide what you want to read next.
Before you use the result
The result counts characters and vocabulary coverage. It is not an official HSK placement test. Familiar words can still appear in unfamiliar grammar.
To keep a word for later, use the text reader and save it to your desk. You can export your study data from Settings & data.
