Free Duplicate Word Checker

Consecutive Duplicate Words
These are words repeated immediately next to each other, such as “the the” or “very very”.
Repeated Words
These words occur more than once anywhere in the analyzed text. Repetition is not necessarily an error; some words naturally occur frequently in well-written documents.

Why Check for Duplicate Words?
Proofreading
Find accidental consecutive repetitions that can occur while drafting or editing.
Academic Writing
Review essays, reports, research documents and other writing before final proofreading.
Business Documents
Check reports, proposals, presentations and other professional documents for accidental duplication.
Website Content
Review web copy and marketing content before publication.
Important Note About Repeated Words
A repeated word is not automatically a writing error. Words such as “and”, “the”, “of” and important technical terms may naturally appear many times. Use the results as an editing aid rather than automatically removing every repeated word.
How It Works
The tool identifies words, compares them without treating capitalization as significant, counts their occurrences and checks adjacent words for immediate repetition. Punctuation is separated from the basic word comparison.
