Repeated Phrase Detector

Find words, phrases and sentences that repeat in your text — useful for tightening up writing, essays and SEO copy.

What is a Repeated Phrase Detector?

This tool scans your text and finds words, phrases, and sentences that repeat more often than they should. It's built for writers, students, editors, and SEO content creators who want to catch overused phrasing, accidental duplication, and repetitive filler before publishing.

Why check for repeated phrases?

  • Better writing: repeated phrases often signal lazy or rushed prose. Spotting them helps you vary sentence structure.
  • SEO content quality: search engines can flag pages with excessive phrase repetition or keyword stuffing. This tool helps you catch that before you publish.
  • Editing & proofreading: long documents often end up with accidentally duplicated sentences or paragraphs — the sentence-check mode catches these instantly.
  • Academic writing: students can check essays for repetitive phrasing that professors often mark down.

How to use this tool

  1. Paste or type your text into the box above.
  2. Choose a phrase length (2–6 words) and minimum repeat count.
  3. Click Analyze Text to see repeated phrases highlighted directly in your text, with a full frequency breakdown.
  4. Enable "Also check repeated sentences" to catch whole duplicated sentences too.

Frequently asked questions

Is my text uploaded anywhere?

No. Everything runs locally in your browser — nothing is sent to a server.

What counts as a "repeated phrase"?

Any sequence of consecutive words of your chosen length that appears two or more times in the text, based on your minimum repeat setting.

Why are some common phrases like "in the" excluded?

With "Skip common word phrases" enabled, phrases made entirely of filler words (the, of, and, etc.) are ignored so results focus on meaningful repetition.

Can it detect repeated sentences, not just phrases?

Yes — turn on "Also check repeated sentences" to see full sentences that appear more than once.
