A passive voice checker scans your writing and flags every sentence where the subject receives the action instead of performing it. Consider the difference: “The report was finished by the team” hides who did the work, while “The team finished the report” is direct and confident. Most writers slip into passive constructions without noticing, especially in essays, business emails, and reports where formal language creeps in.
This free passive voice checker highlights passive constructions as you type, counts how many sentences are affected, and scores your text with a simple passive-percentage meter — aim for under 10% for punchy prose. Click any highlight to see a suggested active-voice rewrite. No signup, no watermarks, no uploads: everything runs in your browser, so your drafts stay completely private.
Passive Voice Highlighter
Paste your text — passive constructions are highlighted, counted, and scored.
Heuristic checker: it flags be-verb + past-participle patterns. A few adjectives (like “excited”) can look passive — use your judgment on each highlight.
🔒 100% private — everything runs in your browser, nothing is uploaded.
How to Use the Passive Voice Highlighter
- Paste your text into the box above — an essay paragraph, a business email, a report section, or a full article draft.
- Click “Check Passive Voice” (or leave auto-check on). The passive voice checker scans each sentence for be-verb plus past-participle patterns and highlights every match in yellow.
- Read your score. The meter shows what percentage of your sentences are passive. Under 10% is a good target for most writing; above 25% usually means the text feels vague or heavy.
- Click any highlight to see a suggested active-voice rewrite. Treat it as a starting point — adjust it so it keeps your exact meaning.
- Copy the report if you want a summary of every flagged sentence to review later or share with an editor.
If the input looks empty or has no sentence punctuation, the tool will ask you to add text first. Very long documents work too, but checking one section at a time keeps the feedback focused and easier to act on.
Features That Set This Tool Apart
- Instant highlighting, not just a list: passive constructions are marked in context so you can see exactly which phrase triggered the flag.
- One-click rewrite ideas: unlike a basic highlighter, this passive voice checker suggests an active-voice version whenever it spots a “by” phrase naming the doer.
- Passive-percentage meter: a single number tells you how passive your draft is, with a color-coded target under 10%.
- Auto-check as you type: feedback appears while you write, so you can fix habits in the moment instead of during a separate editing pass.
- Copyable report: export a plain-text summary of every flagged sentence for revision checklists or classroom use.
- Fully private: all analysis happens locally in your browser — nothing is uploaded, stored, or logged.
Passive Voice Checker: Real Examples and Fixes
The fastest way to understand passive voice is to see it side by side with the active version. Run each pair below through a passive voice checker and the left-hand sentence will light up every time:
- Passive: The decision was made by the committee. Active: The committee made the decision.
- Passive: Mistakes were made during the launch. Active: Our team made mistakes during the launch.
- Passive: The report will be delivered by Friday. Active: We will deliver the report by Friday.
- Passive: It has been decided that the policy will change. Active: Management has decided to change the policy.
- Passive: The cake was baked by Maria. Active: Maria baked the cake.
Notice the pattern: passive sentences push the doer to the end (or delete the doer entirely), while active sentences lead with whoever performs the action. That front-loaded clarity is why active voice usually reads as stronger and more confident.
Also notice what the checker does not flag: past-tense active sentences like “The team finished early” are fine, and so are sentences where “be” pairs with an adjective rather than a participle, such as “She is happy.” A good passive voice checker targets the be-plus-participle fingerprint, not every use of the word “was.”
When Passive Voice Is Actually Fine
Even the strictest passive voice checker will flag sentences that are perfectly good writing — because passive voice is a legitimate grammatical choice, not a mistake. Keep it when the doer is unknown, irrelevant, or deliberately unnamed: “The store was robbed last night” works because the robber is unknown, and “Mistakes were made” is a classic (if evasive) way to focus on the outcome rather than the blame.
Scientific and technical writing also leans passive for good reason. “The samples were heated to 200 degrees” keeps the spotlight on the procedure, not the researcher — which is exactly what a methods section should do. Legal and formal documents use it the same way.
The real enemy is not passive voice itself but unintentional passive voice: the kind that creeps in because it sounds formal, while quietly draining energy from your sentences. Use the checker to find it, then keep the instances you chose on purpose and rewrite the rest.
How to Rewrite Passive Sentences in Active Voice
After running a passive voice checker over your draft, rewriting is a three-step habit. First, find the doer — check for a “by” phrase at the end of the sentence, which names whoever performed the action. Second, move that doer to the front as the new subject. Third, swap the be-verb plus participle (“was completed”) for a plain past-tense verb (“completed”). “The bug was fixed by Priya” becomes “Priya fixed the bug.”
When no doer is named, you have two options: supply one from context (“The team approved the budget”) or restructure around the action itself (“Approval came through on Tuesday”). Both beat leaving the sentence in limbo.

Passive Voice Checker: Frequently Asked Questions
What is passive voice, and can you give an example?
Passive voice is a sentence structure where the subject receives the action instead of performing it, usually built from a form of be plus a past participle. In the sentence The cake was baked by Maria, the cake receives the action. The active version, Maria baked the cake, names the doer as the subject, which is shorter, clearer, and more direct.
How does a passive voice checker find passive sentences?
A passive voice checker scans your text for the grammatical fingerprint of passive constructions: a form of the verb be — am, is, are, was, were, been — followed by a past participle such as written, completed, or chosen, often with a by phrase naming the doer. This tool highlights each match, counts the affected sentences, and shows your passive percentage so you can decide what to rewrite.
Is passive voice always wrong?
No. Passive voice is a legitimate grammatical choice, not an error. It works well when the doer is unknown, unimportant, or obvious — the sentence Mistakes were made in the lab report focuses on the mistake, not who made it. The problem is overuse: too many passive sentences make writing vague and wordy. Most style guides suggest keeping passive sentences under about ten percent of your text.
How do I change passive voice to active voice?
Find the doer — often hiding in a by phrase — and make it the subject. Then convert the be verb plus participle into a simple past-tense verb. The report was finished by the team becomes The team finished the report. If no doer is named, supply one from context or rewrite the sentence around the action. Click any highlighted sentence in the tool above to see a suggested rewrite.
Is my text uploaded or stored anywhere?
No. This passive voice checker runs entirely in your browser using JavaScript, so your text never leaves your device. Nothing is uploaded to a server, stored in a database, or logged. You can even disconnect from the internet after the page loads and the tool keeps working, which makes it safe for school essays, business documents, and other sensitive writing.
