This Chinese HSK level checker estimates how hard a Simplified Chinese passage is to read by segmenting it into words, checking each against representative HSK 1–6 vocabulary lists, and reporting the highest level any word reaches. Because HSK is graded by vocabulary rather than by single characters, word-level checking gives learners and teachers a realistic difficulty signal for choosing or creating reading material.
How it works
The HSK scale runs from HSK 1 (easiest, the smallest vocabulary) to HSK 6 (hardest, the largest).
The tool stores representative core words for each band and records every word at the lowest band it
appears in. Since written Chinese has no spaces, it then segments your text with greedy longest-match:
at each position it tries the longest candidate first (up to four characters) and, on a dictionary hit,
records that word’s level before advancing past it. This keeps multi-character words such as 中国 or
因为 intact instead of splitting them into separate characters.
After segmentation the checker reports the highest HSK level reached by any matched word, because the hardest word sets the bar for reading the whole passage. Characters that match no word are counted as beyond HSK 6, and if any appear the overall estimate is reported as beyond HSK 6 to flag advanced or specialised vocabulary. A per-level table shows how many words landed in each band, and the tool lists a few of the hardest words that drove the result so you know what to study next.
Example and tips
Paste a simple sentence such as 我喜欢学习中文 and the matched words — 我, 喜欢, 学习, 中文 — keep it in
the HSK 1–3 range, giving a beginner-friendly estimate. Add a phrase like 经济发展 or 心理 and the
level climbs toward HSK 4–5; introduce a rare literary word and you will see beyond HSK 6. The
hardest-words line points straight at the vocabulary responsible.
Use the result to pick texts that sit around your current level for comfortable reading practice, and mine the hardest-words list for new flashcards. Treat it as a vocabulary-based signal rather than an official score — the real HSK also tests grammar and listening. Because everything runs locally, your text never leaves your device.
