How duplicate words are counted
The finder tokenizes the paste into words, ignores most punctuation, and ranks tokens that appear more than once. You get a frequency-style list rather than a rewritten paragraph, so you decide which repeats are style and which are accidents.
Editing drafts without a grammar suite
Open this page when a blog post overuses “really,” a resume repeats “managed,” or a support macro says “please” in every sentence. It is not a thesaurus and it does not flag grammar. Pair it with the Word Frequency Counter when you want every word, including hapax legomena.
Stopwords and case
Matching is typically case-insensitive for Latin letters so “The” and “the” stack together. Short function words will dominate any English paragraph; that is expected. The list is a diagnostic, not a grade. Text never leaves the browser.
How to use
1. The finder tokenizes the paste into words, ignores most punctuation, and ranks tokens that appear more than once.
2. You get a frequency-style list rather than a rewritten paragraph, so you decide which repeats are style and which are accidents.
Frequently asked questions
Does it highlight duplicates in the original paragraph?
It reports a ranked list of repeated words. It does not annotate the source inline. Copy the list, then edit in your own document.
Are contractions split?
Apostrophes may keep “don’t” as one token or split depending on the tokenizer. Skim the list if you care about contractions.
How is this different from Duplicate Line Remover?
Line remover deduplicates whole rows. This tool counts word tokens inside running prose.
