Duplicate Word Finder & Highlighter
Spot accidental double words and overused vocabulary. This tool highlights sequential duplicates (like 'the the') and provides a frequency list of all repeated terms in your document.
Catching Proofreading Errors
Human eyes often skip over sequential duplicate words (e.g., 'in the the house') because our brains auto-correct them. This tool acts as an aggressive proofreader. It instantly highlights sequential duplicates in bright red, while also providing a secondary table of globally duplicated words to help you improve your vocabulary diversity.
