Besides the document score, the report can show which sentences read as machine generated.
Turning it on
Sentence-level AI findings are an option on the check. Turn on AI content in the composer's options, or in Settings to make it the default for every check. The document-level score is always shown.
What a card shows
The sentence, its likelihood, and a short note on what makes it read that way (even rhythm, generic phrasing, a stock transition). The card offers a rewrite in a more natural register that keeps the meaning, and Ignore for sentences you wrote yourself.
Thresholds
Sentences are shown as findings above one likelihood and marked more strongly above a higher one. Only sentences long enough to judge are scored; short lines and headings are skipped.
What a rewrite does not do
A rewrite changes wording and rhythm; it never changes facts, numbers or quotations, and it never touches a passage that matched a source. Rewriting is an edit you choose, not a way to hide anything: the honest use of this feature is to find the flat sentences in your own draft.
