How to Use the Duplicate Word Highlighter
The Duplicate Word Highlighter scans your text and instantly highlights, in yellow, any word that appears 3 or more times — no settings to configure first. It's not case-sensitive, and only words of 2 or more characters are counted, so short words like "a" or "the" don't clutter the result. The moment you paste in text, the highlighted view updates automatically, letting you see at a glance which words you've leaned on too heavily.
It's useful for reviewing a blog post, cover letter, or email to catch words you repeated without noticing. If a lot of words get highlighted, try swapping in synonyms or restructuring a sentence to add variety. When nothing repeats 3 or more times, you'll see a "No repeated words found" message with your original text shown unchanged, and everything you enter is processed only in your browser — nothing is ever sent to a server.
