Count word occurrences, starting with the most frequent.
How to use Word frequency
- Enter your text in the input field.
- The result updates as you type. Adjust the available settings if needed.
- Review the result, then use Copy result or a download link when available.
What to expect
Count word occurrences, starting with the most frequent. Matching ignores case and follows Unicode word boundaries, with your browser's dictionary for Thai, Chinese and Japanese. Output is tab-separated; stop-word filtering is not available.
