List repeated words and how often they appear.
How to use Duplicate word finder
- 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
List repeated words and how often they appear. Matching ignores case and follows Unicode word boundaries, with your browser's dictionary for Thai, Chinese and Japanese. Results are tab-separated counts, not inline highlights.
