Usage Instructions

About Text Counter

Text Counter is a high-precision text analyzer with the core advantage of intelligent recognition of mixed Chinese-English text. Unlike simple string length calculations, it can distinguish Chinese characters (including rare characters), English words, punctuation (full-width/half-width), and numbers, providing statistical results that conform to language learning habits.

Key Features

  • Precise Word Count: Supports mixed Chinese-English text, Chinese character = 1 word, English word = 1 word
  • Detailed Character Analysis: Distinguishes Chinese characters, English letters, digits, punctuation marks, spaces, etc.
  • Structure Analysis: Counts sentences and paragraphs
  • Keyword Density: Supports keyword density analysis for SEO optimization
  • Character Density: Evaluates text compactness
  • Real-time Calculation: Updates statistics in real-time as you type
  • Privacy Protection: All analysis is performed locally, text content is never uploaded to servers

Counting Standards

Word Count Rules

  • Chinese: Each Chinese character counts as 1 word (includes both Simplified and Traditional Chinese)
  • English: Each consecutive sequence of letters counts as 1 word (separated by spaces or punctuation)
  • Other Languages: Japanese, Korean, Arabic, Russian, etc. are not counted in \"word count\", only in \"character count\"

Chinese Character Recognition

  • Includes both Simplified and Traditional Chinese, unified as \"Chinese Characters\"
  • Supports CJK Unified Ideographs Basic Block (U+4E00-U+9FFF) and Extension blocks (CJK Extension A-E)
  • Ensures that rare characters in ancient texts and names are correctly counted

Other Characters

  • Other language characters (Japanese, Korean, Arabic, Russian, etc.)
  • Emoji, special mathematical symbols, etc.
  • Categorized as \"Other Characters\"
  • Counted in \"character count\" but not in \"word count\"

Punctuation

  • Supports full-width punctuation (e.g., 。， ！ ？)
  • Supports half-width punctuation (e.g., . , ! ?)
  • Includes various special symbols (book title marks, dashes, interpuncts, etc.)

Use Cases

  • SEO Optimization: Use keyword density to adjust article structure
  • Translation Proofreading: Compare Chinese-English word count ratios
  • Content Creation: Meet character limits for social media (e.g., Twitter/Weibo)
  • Academic Writing: Count thesis word count and character count
  • Copy Editing: Check if copy meets word count requirements

FAQ

Q: How do I reset the input content?

A: Click the "Reset" button (rotating arrow icon) in the top-right corner of the input area to clear all entered text and keywords, restoring to the initial state.

Q: Does keyword density calculation distinguish between uppercase and lowercase for English keywords?

A: No, it's case-insensitive. For example, if you enter the keyword "SEO", all occurrences of "seo", "Seo", and "SEO" in the text will be matched and counted. Chinese keywords use full-word matching.

Q: How are paragraphs counted when there are multiple consecutive line breaks in the text?

A: Multiple consecutive line breaks are recognized as paragraph separators. Empty lines are automatically filtered.

Q: Is data automatically saved? Will it be lost when refreshing the page?

A: Yes, entered content is automatically saved to browser local storage. Refreshing the page won't cause data loss, and you can continue editing previously entered content. Data is automatically saved about 400ms after you stop typing.

Q: What happens if the text exceeds 100,000 characters?

A: The input field will prevent further input and display an error message. It's recommended to split long texts into segments for counting, or simplify the content before counting.
