Count Chinese characters and analyze text by HSK proficiency levels. View character frequency rankings, pinyin pronunciations, and vocabulary diversity. Paste Chinese text to identify unique characters and assess difficulty. The HSK breakdown shows which characters belong to each learning stage. Teachers evaluate reading materials, students track progress, and creators match text to target levels. All processing runs locally in your browser.
Paste Chinese text into the input area and click "Count Characters" to analyze character distribution, HSK levels, and frequency. All processing runs locally in your browser.
Type or paste any Chinese text into the text area. The tool handles both simplified and traditional characters, along with mixed Chinese-English content. Clear the default sample text with the "Clear Text" button before entering your own content.
HSK 1-2 (Foundation): 300 characters covering 60-70% of everyday text. Characters like 我 (wǒ, I), 你 (nǐ, you), and 是 (shì, to be) appear here. If a text shows mostly HSK 1-2 characters, beginners can read it with reasonable comprehension.
HSK 3-4 (Intermediate): 1,200 total characters. Learners handle daily life situations and workplace communication. Texts at this level suit learners with 1-2 years of study. You can read news articles with dictionary support.
HSK 5-6 (Advanced): 2,500-5,000 characters. Read native-level materials including literature and academic papers. High HSK 5-6 counts indicate sophisticated content requiring advanced proficiency.
Unclassified Characters: Rare characters, names, and specialized terms outside HSK vocabulary. A text with many unclassified characters might be highly specialized or use classical elements.
The top 20 frequency list shows which characters appear most often in your text. Chinese has over 50,000 characters, but the top 500 account for roughly 75% of text. The top 1,000 cover about 89%. Learning high-frequency characters first maximizes reading ability for effort invested.
Use the frequency list to identify theme-specific vocabulary. Technology texts show high frequency for characters like 电 (diàn, electricity) and 机 (jī, machine). Business texts emphasize 公 (gōng, public) and 司 (sī, company). Recognizing patterns helps you learn vocabulary relevant to your interests.
Compare the frequency list against characters you know. If the top 20 includes many unfamiliar characters, the text exceeds your current level. If you recognize most top characters but struggle with the text, the challenge lies in vocabulary combinations or grammar rather than individual characters.
Diversity measures unique characters relative to total characters. A 30% score means roughly 30 unique characters per 100 total. Children's books show 20-30% diversity with repetition for learning. News articles range 35-45%. Academic papers exceed 50% with precise vocabulary.
Use diversity to select appropriate reading materials. Beginners benefit from 25-35% diversity where repetition aids comprehension. Intermediate learners handle 35-45%. Advanced learners manage 45%+ without excessive dictionary use.
The grid displays all unique characters with pinyin pronunciation. Scan it to identify characters you recognize versus those needing study. This assessment is faster than reading the full text. Each character shows the most common pronunciation—for characters with multiple readings, context determines the correct one in your specific text.
Advanced learners can spot character components and radicals. Characters sharing the water radical (氵) often relate to liquids: 河 (hé, river), 海 (hǎi, sea). The grid reveals these patterns across your text's vocabulary.
Text Selection: Before reading new material, paste it into this tool. If over 70% of characters fall within your HSK level or below, the text suits your ability. This pre-reading assessment prevents frustration.
Progress Tracking: Paste the same text at different points in your learning journey. As you progress, the percentage of characters you recognize increases. The HSK distribution shifts toward lower levels relative to your ability.
Vocabulary Lists: Export unfamiliar characters to flashcard apps like Anki or Pleco. Focus on high-frequency characters first—they appear most often in future reading.
Teacher Resources: Analyze texts before assigning them. Ensure reading materials match class proficiency by checking HSK distributions. Identify characters students might struggle with and pre-teach them.
Chinese vs. Non-Chinese: Modern texts often mix hanzi with Latin letters and numbers. High non-Chinese counts indicate technical content using English terms or mixed-language writing.
Punctuation: The tool counts both Chinese punctuation (，。！？) and standard marks. High Chinese punctuation counts indicate authentic writing. Mixed punctuation might suggest translated content.
Simplified vs. Traditional: The tool recognizes both. However, simplified and traditional versions of the same character count separately—国 and 國 appear as different entries. This matters when analyzing texts from different regions.
Character vs. Word Counting: This tool counts individual characters, not words. A two-character word like 学习 (xuéxí, to study) counts as two characters. Recognizing characters precedes recognizing words.
