How to Find Duplicate Words
Paste or type your text into the Original Text box. The finder scans the words, highlights repeated ones in the full text, and shows a matching color label for each duplicate word. It updates as you type, so you can review your text without submitting or uploading it.
- Enter or paste a sentence, paragraph, essay, or other text into the Original Text box.
- Look at the highlighted text to see where repeated words appear.
- Match each highlight color to the corresponding word and count in Duplicate Words Found.
- Adjust the options to ignore capitalization or common English words.
What the Duplicate Word Finder Detects
This tool finds words that appear more than once anywhere in the text. The repeated words do not need to be next to each other. For example, if “draft” appears in the first and fourth sentences, both occurrences are highlighted.
It also detects adjacent repeats such as “the the” or “very very.” Punctuation and spacing between occurrences do not prevent a word from being counted again.
Understand the Results
- Words Scanned is the number of words detected in your text. It includes common words even when the common-word filter is enabled.
- Duplicate Words is the number of distinct words that appear more than once after applying your options.
- Extra Occurrences counts the repeated appearances beyond the first occurrence of each duplicate word.
For example, if “draft” appears three times, it is one duplicate word with two extra occurrences. The matching highlight and label use the same color. Counts appear in parentheses next to each word.
Choose Your Options
Ignore capitalization
This option is selected by default. It treats uppercase and lowercase versions of a word as the same word, so “Draft” and “draft” are counted together. Clear the checkbox to treat them as separate words.
Ignore common words
Select this option to leave frequent English words, such as “the,” “and,” and “of,” out of the duplicate results. It can help when you want to focus on repeated names, ideas, or content words. The filter changes the duplicate results and highlights, while Words Scanned still reports all words in the text.
Example: Find Repeated Words in a Paragraph
Consider this text:
The draft is clear, but the draft is too short. It is clear.
With Ignore capitalization selected and common words included, “the,” “draft,” “is,” and “clear” each appear twice. The tool highlights both occurrences of each word and shows (2) next to each label. If you turn on Ignore common words, “the” is excluded from the duplicate results.
Use It While Editing
Repeated words can be intentional, especially in dialogue, instructions, or text that needs consistent terminology. Use the highlights as an editing aid: check whether each repetition is needed, then revise only where it improves clarity or flow. The finder identifies repetition; it does not decide whether a repeated word is an error.
You can paste text copied from a document or webpage, review the highlighted version, and then make edits in your original document. The tool does not change your source text.
Frequently Asked Questions
Does the finder detect words repeated next to each other?
Yes. A phrase such as “the the” is detected as a repeated word. Turn on Ignore common words if you want to exclude “the” from the results.
Does it find a word if the repetitions are far apart?
Yes. A word is counted as a duplicate when it appears more than once anywhere in the text, whether the occurrences are adjacent or separated by other words or sentences.
Can I treat uppercase and lowercase words differently?
Yes. Clear Ignore capitalization to count differently capitalized versions as separate words. Leave it selected to count them together.
Does Ignore common words remove them from Words Scanned?
No. Words Scanned includes all detected words. The option only excludes common English words from the duplicate count, labels, and highlights.
