What the tool finds
- All repeated words: A frequency list of terms used more than once, with a minimum threshold you control (great before final polish with the Readability Score Checker).
- Consecutive duplicates: Instant detection of double words like is is, can can, or the the.
- Smart filters: Toggle case sensitive, ignore stopwords (the, and, of), and ignore numbers.
- Live highlight: See duplicates highlighted as you type or paste for a quick proofreading pass.
How to use it

Prepping text from PDFs or emails? Use Whitespace and Formatting Cleaner and Remove Empty Lines for a smooth paste. For lists and columns, the Text ↔ List Converter is ideal; to alphabetize or deduplicate lists, try the Alphabetizer.
- Set a minimum: Raise Min occurrences to surface meaningful repetition instead of deliberate emphasis.
- Case matters: Enable Case sensitive to distinguish Apple (company) from apple (fruit).
- Skip stopwords: Ignore common words to focus on content terms you overuse.

Why catching duplicates matters
Duplicate words distract readers, dilute key points, and look unprofessional in resumes, emails, reports, and blog posts. Removing them sharpens clarity, improves flow, and boosts trust. It is a fast win before grammar and style passes with the Grammar Corrector and final checks using the Readability Score Checker.
