How to check a scene for repetition

  1. Paste your scene or chapter.
    Use a complete passage so the checker can distinguish a real pattern from a word that happens to appear twice.
  2. Review repeats, echoes, and crutch words.
    Start with nearby echoes because readers are most likely to notice the same distinctive word repeated within a few sentences.
  3. Revise, then paste again.
    Keep intentional motifs and rhythm. Replace, remove, or restructure only the repetition that distracts from the scene.

What the report means

The repeated-words section ignores common function words and raises the threshold as the passage gets longer. Phrase results look for recurring two- and three-word sequences. Echoes are stricter: a content word of at least four letters must appear three or more times inside a 50-word window.

Crutch words are not forbidden words. Terms such as “just,” “really,” and “suddenly” can be exactly right in dialogue or close point of view. Filter words such as “saw,” “felt,” and “noticed” can add useful distance. The report identifies revision candidates; it does not make a stylistic decision for you.

Repetition checker FAQ

What does this repetition checker do?+
It finds unusually frequent content words and phrases, nearby word echoes, common crutch words, and perception filters. It also reports sentence count and lexical variety.
Why does word repetition weaken prose?+
An accidental echo can pull attention away from the scene and toward the wording. Repeated weak modifiers can also flatten emphasis because every moment receives the same signal.
Is repetition ever good in fiction?+
Yes. Deliberate repetition creates rhythm, emphasis, motifs, and character voice. This checker flags candidates for review; the writer decides what is intentional.
Is my text stored anywhere?+
No. Analysis runs entirely in your browser. The text is not sent to Arbento, an AI service, or any other server.
How is this different from ProWritingAid's repetition checker?+
This page works immediately without an account, has no artificial word cap, keeps the text in the browser, and frames every result as a fiction revision signal rather than an automatic correction.
