About this tool
- 1
Paste the text
Enter at least 50 words. Two hundred or more gives far steadier numbers.
- 2
Run the analysis
Six style measures are computed and combined into a single 0-100 style score.
- 3
Read the breakdown
Each measure shows its own value and weight, and every sentence is scored individually.
- 4
Use it to edit
Treat a high score as a prompt to vary sentence length, cut transition words, and widen your vocabulary.
- The six measures are type-token ratio, sentence-length burstiness, repeated three-word phrases, sentence-length standard deviation, hapax ratio, and transition words per sentence.
- Low burstiness - every sentence the same length - is the single strongest driver of a high score.
- Formulaic human writing (legal boilerplate, technical manuals, exam prose) scores high. That is a property of the style, not of the author.
- Short samples are unstable. Under 200 words, one long sentence can swing the score by 10 points.
- Six weighted style measures with individual scores
- Vocabulary diversity (type-token and hapax ratios)
- Sentence-length burstiness and standard deviation
- Repeated-phrase and transition-word density
- Sentence-by-sentence breakdown and editing suggestions
- Runs entirely in your browser
- Find the passages in your own draft where every sentence has the same shape.
- Check whether a piece leans on however, moreover, and furthermore.
- Measure vocabulary variety across drafts of the same text.
- Give a writer concrete, countable feedback instead of "it reads flat".
No, and it would be dishonest to say it did. It measures six surface statistics - word variety, sentence-length variation, repetition, and transition-word density - and reports them. Those statistics are correlated with the flat, even style typical of unedited language-model output, but they are not evidence of authorship. No tool on the open web, including the commercial detectors, can reliably prove that a piece of text was machine-written.
The score is a summary of how uniform and repetitive the writing is. It is useful as an editing signal - "these paragraphs are monotonous" - and it is not useful as a verdict about who or what wrote them.
Please do not use it as evidence. Formulaic human writing scores high and lightly edited machine writing scores low, so decisions made on this number will be wrong in both directions. Use it to start a conversation about the writing itself, never to make an accusation.
