Beyond word count, it also shows character count, sentence count, paragraph count, and estimated reading time. Everything runs locally with no data uploaded.

Frequently asked questions
Does it work with Chinese, Japanese, and Korean?
Yes. Unlike simple space-based word counters, this tool uses Intl.Segmenter for accurate word boundary detection in Chinese (no spaces between words), Japanese (mixed scripts), Korean, and 100+ other languages.
How accurate is the word count compared to Microsoft Word or Google Docs?
The counting uses the same Unicode text segmentation standard (UAX #29) as professional word processors. Results are equivalent to Word and Google Docs for standard text. Minor differences may occur with highly specialized Unicode content.
How is the reading time calculated?
Reading time is based on an average adult reading speed of 238 words per minute (from a 2019 meta-analysis of 190 studies). Speaking time uses 150 words per minute, a standard rate for presentations and narration.
How does it handle mixed English-Chinese text?
Intl.Segmenter handles mixed-language text natively. English words are detected by spaces, while Chinese characters are each treated as a word unit. The result is an accurate total word count across both languages.
How are paragraphs counted?
Paragraphs are detected by blank-line separation. One or more consecutive non-empty lines, separated from the next block by at least one blank line, form a single paragraph. This matches the standard definition used in word processors.
