What is a duplicate word finder?
A duplicate word finder is a tool that identifies words that appear multiple times in your text. It helps writers, editors, and content creators identify repetitive language that can make their writing less engaging or professional. Our tool highlights duplicate words in real-time with color-coded highlighting and provides detailed statistics.
How does the duplicate word finder work?
The tool analyzes your text and identifies words that appear multiple times based on your settings. You can set a minimum word length (to ignore short words like "a" or "the") and a minimum repeat count (e.g., words that appear 2+ times). The tool then highlights these duplicates with different colors and displays them in a list with their occurrence counts.
What is the minimum word length setting?
The minimum word length filter allows you to ignore short words when detecting duplicates. For example, if set to 4, words shorter than 4 characters (like "a", "the", "is") will be ignored. This helps focus on meaningful duplicate words rather than common articles and prepositions that naturally repeat in text.
What is the minimum repeat count?
The minimum repeat count determines how many times a word must appear before it's considered a duplicate. For example, if set to 2, only words that appear at least twice will be highlighted. If set to 3, only words appearing three or more times will be shown. This helps you focus on the most repetitive words in your text.
What is case sensitivity?
Case sensitivity determines whether the tool treats "Word" and "word" as the same word or different words. When case-sensitive mode is off (default), "Word" and "word" are considered duplicates. When enabled, they are treated as separate words. This is useful when you want to detect specific capitalization patterns.
Can I toggle highlighting for individual words?
Yes! You can click on any word in the duplicates list to toggle its highlighting on or off. This allows you to focus on specific duplicate words while temporarily hiding others. The highlighting state is preserved as you edit your text.
Does the tool work with different languages?
The tool works best with languages that use spaces to separate words (like English, Spanish, French, etc.). It may not work as effectively with languages that don't use spaces (like Chinese or Japanese) or languages with complex word boundaries. The tool uses word boundary detection based on alphanumeric characters and apostrophes.
Is my text stored or sent to servers?
No, your text is never stored or sent to any server. All processing happens entirely in your browser using JavaScript. This ensures complete privacy and security for your content. You can use the tool with sensitive or confidential text without any concerns.
How can I use this tool to improve my writing?
The duplicate word finder helps you identify repetitive language that can make your writing less engaging. By finding words you use too frequently, you can: diversify your vocabulary, improve readability, create more varied prose, identify overused terms, and enhance overall writing quality. It's particularly useful for editing longer documents, blog posts, articles, and creative writing.
Can I export the list of duplicate words?
Yes! You can copy the list of duplicate words by clicking the copy icon next to the "Duplicates" heading. This copies all duplicate words with their counts in a text format that you can paste into other applications or documents.
What is the undo/redo feature?
The undo/redo feature allows you to revert changes to your text. You can undo changes using Ctrl+Z (Cmd+Z on Mac) and redo using Ctrl+Shift+Z (Cmd+Shift+Z on Mac). The tool maintains a history of up to 50 text states, allowing you to navigate through your editing history.
Why should I care about duplicate words?
While some word repetition is natural and necessary, excessive repetition can make your writing feel repetitive, unprofessional, or monotonous. Identifying duplicate words helps you: create more engaging content, improve readability, develop a richer vocabulary, avoid redundancy, and produce higher-quality writing that keeps readers engaged.
