This is English prose, and I understand the result does not establish AI authorship.

What the percentage means

Visible patterns.
Explainable results.

The score is the percentage of sentences that match one or more of these rules. Each sentence counts once, even when it matches several rules.

Long sentence

35 or more words. Review clarity; long sentences are common in human academic writing.

Repeated opening

The same first three words occur in at least three sentences. Review variety; assignment structure can cause repetition.

Repeated phrase

The same four-word sequence occurs in at least three sentences. Review repetition; technical terms and quotations can legitimately repeat.

No trained detection model is used. These are editorial rules, not validated indicators of AI use. A high score can reflect ordinary human writing; a low score does not verify human authorship.

Privacy and limitations

Your text, filename and results are not uploaded or saved by this tool. They remain in temporary page memory until cleared or the page is closed or reloaded. Reports download only when you request them. Ordinary website analytics still apply, but the tool does not send document contents, names or scores as analytics events.

Designed for English prose. Short texts, code, lists, quotations, specialist terms and structured assignments can produce misleading patterns. This tool does not check plagiarism, citations or factual accuracy. File extraction and sentence splitting may be imperfect: inspect the preview.
