How it works
Extract runs of Unicode letters or digits, including internal straight or curly apostrophes, then count and rank by frequency.
Input definitions
- Text
- Plain text; maximum 200,000 characters.
- Case matching
- Choose Ignore case / Case sensitive.
A worked example
- Text
- Hello hello world
- Case matching
- Ignore case
Assumptions & limits
Punctuation separates tokens; no stop-word removal. Compound words split at hyphens. CJK text may be counted as a continuous run.

Common questions
Why does this count differ from the word counter?
The frequency tool tokenizes runs of Unicode letters and digits, with internal apostrophes. The general word counter splits on whitespace. Hyphens, punctuation and continuous CJK text can therefore produce different counts.
Can I paste formatted documents into this text tool?
The tool processes plain text. Styling, document structure and rich-text metadata are not preserved. Copy the result before closing the page.
