This tool surfaces two different kinds of repetition. The first is a straightforward frequency list of every word appearing more than once, which is how you catch a term leaned on thirty times across an article. The second is the accidental double word — 'the the', 'is is' — which happens constantly when editing mid-sentence and which spellcheckers routinely miss because both words are spelled correctly. Editors, students and content teams use it as a final pass before publishing. For SEO work it doubles as a keyword-stuffing check: if a target phrase appears far more often than the natural rate of roughly 1-2% of total words, the copy reads as over-optimised.
