Frequently Asked Questions

What types of duplicate words does this tool find?

The tool finds several types of duplicates: consecutive duplicates where the same word appears twice in a row (like 'the the'), nearby duplicates where a word repeats within a few words (like 'good product, really good'), and paragraph-level duplicates where words appear unusually frequently in sections. You can customize the detection sensitivity to match your needs.

Why are duplicate words a problem in writing?

Duplicate words, especially consecutive ones, are common typing errors that make writing look unprofessional and careless. They disrupt reading flow, distract readers, and suggest lack of proofreading. While occasional repetition can be rhetorical, unintentional duplicates weaken your writing's credibility and clarity. Catching these before publication shows attention to detail and professionalism.

Can I exclude common words like 'the' and 'and' from detection?

Yes! The tool offers a stop word filter that excludes common articles (a, an, the), prepositions (in, on, at, to, for), and conjunctions (and, but, or, nor) from duplicate detection. This focuses results on meaningful word repetition while ignoring naturally occurring grammatical words.

What's the difference between case-sensitive and case-insensitive modes?

Case-insensitive mode treats 'Word', 'word', and 'WORD' as the same word and flags them as duplicates. Case-sensitive mode treats them as different words. For most proofreading, case-insensitive mode is better because 'The product is good. The product is affordable.' shows unintentional repetition regardless of capitalization.

Is this duplicate words finder free?

Yes! Our duplicate words finder is completely free to use with unlimited checking and no registration required.

Will my text be stored or shared?

No. All duplicate detection happens entirely in your browser using JavaScript. Your text is never sent to our servers, stored in databases, or shared with anyone. Your content remains completely private.

Does it work on mobile devices?

Absolutely! The duplicate words finder is fully responsive and works perfectly on smartphones, tablets, and desktop computers.
