🖍️Duplicate Word Highlighter

Highlight words that repeat throughout your text

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.
