This tool scans every sentence for the pattern and highlights matches. Some constructions are ambiguous; treat the results as a guide rather than an absolute count.
A small amount of passive voice is fine — but most engaging writing keeps it under 10%.
We look for "be" forms (am, is, are, was, were, be, been, being) followed within 3 words by a past participle (verbs ending in -ed, -en, plus common irregulars).
Yes. Use passive when the actor is unknown ("The lock was broken") or when you want to emphasise the action over the actor. Aim for under 10% in most writing.
