This is a vocabulary estimate, not an official HSK assessment. The grade is the highest word level when every Chinese word is listed. Unlisted words leave the sentence unclassified; they may be names, compounds or vocabulary outside HSK. Levels 7–9 are grouped. Grammar, idioms and listening difficulty are not assessed. Automatic word splitting can be imperfect.
The 2025 mapping covers all 11,000 syllabus entries. Where a spelling has multiple readings or senses, lookup uses its lowest introduction level. Traditional text is converted to simplified for lookup. HSK vocabulary: complete-hsk-vocabulary by Yanis Zafirópulos (MIT) for HSK 2.0; the full 2025 syllabus transcription is from hsk-tutor.com, with original syllabus rights retained.
