How we mark adverbs and passive voice
Adverbs: a word that ends in “ly” is marked, except a short list of common words that are not being used as style-adverbs here (only, early, family, weekly, apply, and others like them). “Really” and “slowly” will be marked. This will sometimes mark a word you are happy with. That is the point of a pencil, not a judge — you decide.
Passive voice: we look for a form of be followed by a past participle (words ending in “ed”, plus a list of irregulars such as written, shown, done, made). “The report was written” is marked. “The team wrote the report” is not. This is the same kind of pattern Hemingway Editor popularised. It will miss some passives and will flag a few lines that are not really passive. It does not call an AI model.
