How duplicate word finder works
Two failure modes hide in every draft: accidental doubles like the the, of of and is is left behind by an editing slip, and unconscious overuse where a favourite word appears four times in a paragraph. This tool catches both. It tokenizes your text into words — handling apostrophes in don’t and hyphens in well-known — then walks the sequence looking for the same word twice in a row, merging longer runs so the the the counts as one three-word repeat.
Every adjacent repeat is reported with the word, how many times it repeats, its position in the word stream, and a text excerpt around it so you can jump straight to the spot in your document. Case is ignored by default — The the is still a duplicate — but you can switch that off for case-sensitive material. A minimum word length setting skips short words like a and to when you only care about substantial repeats.
Below the adjacent repeats, a frequency list ranks every word that appears more than once, sorted by count, so you can see that barely appeared six times and decide whether that is voice or crutch. Nothing is uploaded; the analysis runs entirely in your browser, which makes it safe for unpublished drafts, client copy and confidential documents.
