About This Tool

This tool scans text and reports which words repeat and how often, highlighting overused terms. Writers use it to catch unintentional repetition that makes prose feel monotonous, and to check keyword frequency without padding a page with the same term.

It counts occurrences of each distinct word, usually ignoring case and common filler words so the signal is not drowned by the, and, and of. Seeing the frequency list makes it easy to spot a word you have leaned on too heavily and to vary the language before publishing.

Repetition is not always a fault: a deliberately repeated word can add rhythm or emphasis, and technical writing often must reuse a precise term rather than reach for a vaguer synonym. The tool gives you the data to decide, not a rule to obey. Reading the frequency list next to your draft makes it easy to separate purposeful repetition from the accidental kind that flattens a paragraph.

How to Use It

  1. Paste your text.
  2. Read the list of repeated words with their counts.
  3. Revise the passages where a word appears too often.
