How it works
Passive voice hides who does the action: "mistakes were made" instead of "we made mistakes". This detector scans your text for the tell-tale pattern — a form of "to be" or "get" (is, are, was, were, be, been, being, got) followed by a past participle (written, made, chosen, reviewed) — and highlights every phrase it finds, plus the whole sentence around it. The stats show how many of your sentences are passive and what percentage that is, so you can aim for the usual editorial target of under 10 percent.
The verb lists and the matching rules are built into the page, so the whole analysis runs in your browser in plain JavaScript: nothing you paste is uploaded, stored or sent to any server. It is a heuristic, not a grammar engine, so scan the results yourself — a few passive sentences are fine when the doer genuinely does not matter.
Frequently asked questions
What is passive voice, and how does the detector find it?
In the passive voice the thing receiving the action comes first and the doer is hidden or pushed to the end: "the report was written by the team" instead of "the team wrote the report". The giveaway is a form of "to be" or "get" — is, are, was, were, be, been, being, got — followed by a past participle such as written, made, chosen or reviewed. This tool scans for exactly that pattern, including versions split by an adverb ("was recently updated") and perfect forms ("has been deployed"), then highlights the phrase and the sentence it sits in.
What percentage of passive voice is acceptable?
Most editorial style guides aim for under 10 percent of sentences in the passive voice, which is the threshold this tool calls "Good". Between 10 and 20 percent reads as "Fair" and anything over 20 percent is flagged as "High". Passive voice is not a grammar error, though: it is the right choice when the doer is unknown, obvious or irrelevant ("the server was restarted overnight"), so read each flagged sentence before rewriting it.
Is my text uploaded anywhere?
No. The verb lists and the matching rules are embedded in the page, so the entire analysis runs in your browser with JavaScript. Nothing you paste leaves your device, nothing is stored, and there is no account, no ad tracking and no character limit beyond a 200,000-character safety guard. You can even load the page once and keep using it offline.
