❓ Frequently Asked Questions
How does the word counter work?▼
Our word counter analyzes your text in real-time. It counts English words by splitting on spaces and punctuation, counts Chinese characters separately using Unicode detection, and calculates sentences, paragraphs, and reading time based on standard averages.
Does this tool support multiple languages?▼
Yes! The tool counts English words and Chinese characters separately. It can handle mixed-language text. The interface is also available in both English and Chinese.
How is reading time calculated?▼
Reading time is calculated based on an average reading speed of 200 English words per minute and 400 Chinese characters per minute. Speaking time uses 130 words per minute.
How does the text diff comparison work?▼
The text diff tool compares two texts line by line using a Longest Common Subsequence (LCS) algorithm. Lines present only in Text A are marked as removed (red), lines only in Text B are marked as added (green), and matching lines are shown as unchanged.
Is my text data stored or sent to any server?▼
