About this tool
This tool is a heuristic helper, not a perfect grammar checker. It looks for a form of be, such as was or were, followed by a past participle, including common irregular forms like written and taken. It can miss passives with other helpers and can flag a few borderline cases, so read each match in context before rewriting.
Frequently asked questions
Is this detector perfectly accurate?
No. It is a heuristic based on be-verbs plus participles, so it can miss some passives and flag borderline cases. Treat matches as candidates to review.
Does it catch passives without a be-verb?
Not reliably. Constructions built with other helpers or with no helper at all may slip past this pattern.
