Frequently Asked Questions
Is this tool completely free?
Yes. The tool is 100% free to use with no registration, no subscription and no usage limits.
You can use it as many times as you need for personal or commercial projects without any cost.
We believe developer and productivity tools should be accessible to everyone without paywalls.
What is case-sensitive matching?
By default the tool treats Hello and hello as the same word. Enabling case-sensitive mode keeps them separate.
This is useful when working with code, proper nouns or technical documents where case carries meaning.
Toggle the option before clicking Find Duplicates to control how the comparison works.
What common words are ignored?
The ignore common words option filters out frequently used English words such as the, a, an, is, are, was, and, or, but, in, on, at, to and similar function words.
This helps writers focus on meaningful word repetition rather than grammatical words that naturally appear many times.
Uncheck this option if you need to find all repeated words including common ones.
What do the position numbers mean?
Position numbers show the word order in the text. For example, position 3 means the word was the third word in your input.
If a word appears more than ten times only the first ten positions are listed followed by an ellipsis.
Use these positions to navigate quickly to each occurrence of a repeated word in your document.
