Frequently asked questions
- How is passive voice detected?
- This tool uses a heuristic: it looks for a 'to be' verb (is, are, was, were, etc.) followed by a word ending in -ed or -en in the same sentence. It is an estimate, not a grammar parser.
- How much passive voice is acceptable?
- Most style guides recommend keeping passive voice below 10% of sentences. Active voice is generally more direct and engaging.
