Frequently asked questions

How are duplicate words counted?

The tool splits your text into words using spaces and punctuation boundaries. It groups matching words, counts their frequency, and displays all words with 2 or more occurrences.

What is the difference between Keep First and Remove All?

Keep First keeps the first occurrence of a duplicate word and deletes subsequent ones. Remove All completely removes the word from the text wherever it occurs.

Does it ignore punctuation or line breaks?

Yes. With the "Ignore Punctuation" option checked, punctuation marks next to words (e.g. "word," vs "word") are ignored so they match as duplicates.
