Find and highlight every repeated word in your text. Instantly see which words appear more than once, sorted by frequency. Filter by minimum count, ignore common stop words, and choose between case-sensitive and case-insensitive modes.
Paste any text — an essay, article, product description, email or social post — into the input box. The tool scans all words instantly as you type or paste, with no character limit.
Every word that appears more than once is highlighted in your text. The results panel lists all duplicates sorted by frequency (most repeated first), with an exact count for each. Click any word in the list to jump to its first occurrence.
Use the minimum count filter to show only words repeated 3+ or 5+ times. Toggle the stop-word filter to hide common words like "the", "and", "is" that are expected to repeat. Switch between case-sensitive and case-insensitive modes depending on your use case.
Repeated words are one of the most common signs of weak writing. When the same word appears multiple times in a short span, readers notice the repetition even if they cannot identify it consciously — it creates a monotonous rhythm. Duplicate word checking is particularly important for product descriptions (where Google penalises keyword stuffing), academic writing (which penalises stylistic repetition), and UX copy (where repeated words in menus and labels cause confusion).
A duplicate word is simply any word used more than once. Keyword stuffing is a specific SEO black-hat practice where a target keyword is inserted unnaturally into content far beyond what reads naturally. This tool identifies duplicates generally — it is up to you to judge which repetitions are intentional (consistent use of a product name) and which are unintentional (over-relying on the word "great").
Stop words are the most common words in a language — articles ("a", "the"), prepositions ("in", "on", "at"), conjunctions ("and", "but", "or"), and pronouns ("it", "they", "we"). These words appear frequently in all text by necessity and are not meaningful signals of repetition. Filtering them out lets you focus on content words — nouns, adjectives, and verbs — that carry meaning and where repetition is a genuine stylistic concern.
Yes. In case-insensitive mode (the default), "Word", "word", and "WORD" are all counted as the same word. In case-sensitive mode, they are counted separately. Use case-insensitive mode for most writing checks. Use case-sensitive mode if you are checking code, configuration files, or text where capitalisation carries specific meaning.
A word frequency counter lists every word and how often it appears, including words that appear only once. A duplicate finder focuses exclusively on words that appear more than once, making the repetition problem visible rather than burying it in a full frequency table. This tool combines both — the highlight view shows repetition in context, while the frequency panel gives you a ranked list.
This tool checks individual words. For repeated phrases (also called n-grams or duplicate sentences), you would need a more specialised text analysis tool. Phrase repetition is less common than word repetition and is typically a concern in plagiarism detection rather than style editing.
