Checking your own writing for repetition
Repeated phrases, monotonous sentence lengths and long run-on sentences make writing feel flat, and they are easy to miss in your own text. A quick structural check before you publish catches them while they are still cheap to fix.
Paste a draft and this checker reports the three-word phrases you repeat, the variety of your vocabulary, the average sentence length and an overall signal of low, medium or high, with a short note on what to look at. It is writing guidance, not a plagiarism verdict.
How to use it
- Paste your draft into the input box.
- Read the repeated phrases, most frequent first.
- Check the lexical diversity and average sentence length.
- Revise the flagged spots, then paste the new version to compare.
Example: a phrase used three times
We grow fast. We grow fast because we listen. We grow fast and we ship.
Repeated: "we grow fast" × 3 Lexical diversity: 0.467 Average sentence: 5 words Signal: medium
Fifteen words but only seven different ones, so the diversity score is low. Repetition can be a deliberate rhetorical device; the report just makes it visible.
What the numbers mean
Lexical diversity is the number of distinct words divided by the total number of words. Short texts naturally score higher, so compare drafts of similar length. Average sentence length matters for readability: around 15 to 20 words is comfortable for most readers, while an average above 25 often signals sentences that should be split.
The overall signal rises with the number of repeated phrases relative to the length of the text, with very long average sentences and with long runs of words without punctuation.
This is not a plagiarism checker
The tool looks only at the text you paste. It does not compare it against the web, books or student papers, so it cannot say whether text was copied. Real plagiarism detection needs a large database of sources. Use this page to polish your own writing, and treat its signal as advice rather than evidence about anyone.
Fixing repetition
Not every repeat needs a synonym: technical terms should stay consistent, and a deliberate repeat can give a speech rhythm. Look for accidental ones, such as the same sentence opening three times in a paragraph. Combining two short sentences, starting with a different element, or cutting a filler phrase usually fixes them better than a thesaurus.
Questions
Does it work for languages other than English?
Yes, words in any alphabet are counted. The guidance thresholds were chosen with English prose in mind.
Can it detect AI-written text?
No. Detecting AI text is unreliable even for dedicated services, and this tool makes no such claim.
Is my text uploaded?
No. The analysis runs in your browser and nothing is stored.
