Check for Passive Voice Instantly

Passive voice is the quiet killer of clear writing. It makes sentences longer, hides who actually did the work, and drains the energy from your copy. A passive voice checker flags those sentences in seconds so you can rewrite them into something punchier, more persuasive, and easier to read.

This guide explains what passive voice is, how to spot it, why it matters for SEO and conversions, and exactly how to turn passive sentences into active ones — without sounding robotic.

What Is Passive Voice?

In an active sentence, the subject performs the action: "The team shipped the feature." In a passive sentence, the subject receives the action: "The feature was shipped by the team." The doer either trails behind a "by" phrase or disappears entirely.

Grammatically, passive voice is built from a form of the verb "to be" (is, are, was, were, been, being) plus a past participle (shipped, written, designed, chosen). When you see that pattern — "was written", "are designed", "has been chosen" — you are almost certainly looking at passive voice.

Active vs Passive Voice: Side by Side

Notice how every active version is shorter, clearer about who acts, and more confident. That is the whole game.

Why Passive Voice Hurts Your Writing

• It is wordier. Passive constructions add helper verbs and "by" phrases, inflating word count without adding meaning.
• It hides responsibility. "Mistakes were made" dodges the question of who made them — readers notice the evasion.
• It is harder to scan. Readers process active sentences faster, which lifts dwell time and engagement signals search engines care about.
• It weakens calls to action. "Get started today" beats "Getting started can be done today" every time.

How to Find Passive Voice

1. Look for "to be" plus a past participle

Scan for is/are/was/were/be/been/being followed by a verb ending in "-ed" or an irregular participle like written, built, or chosen. That two-word fingerprint catches the vast majority of passive sentences. A passive voice checker automates this so you do not have to read line by line.

2. Try the "by zombies" test

If you can add "by zombies" after the verb and the sentence still makes grammatical sense, it is passive. "The feature was shipped by zombies" works, so it is passive. "The team shipped the feature by zombies" does not, so it is active.

3. Flag long sentences at the same time

Passive voice and runaway length often travel together. Sentences over about 25 words force readers to slow down and re-read. Flagging both at once — as this tool does — gives you a fast, prioritized edit list.

How to Fix Passive Voice

Name the actor and move it to the front

Find who or what performs the action and make it the subject. "The email was sent by Sarah" becomes "Sarah sent the email." If the original sentence hides the actor, you may need to add one — that extra clarity is usually an improvement.

Choose a stronger verb

Passive sentences lean on weak "to be" verbs. Replacing "was responsible for managing" with "managed" removes the passivity and three words in one move.

Know when passive is the right call

Passive voice is not always wrong. Use it when the actor is unknown ("The store was robbed overnight"), irrelevant ("The samples were refrigerated"), or when you deliberately want to emphasize the receiver ("Our customers are valued"). Aim to keep passive sentences under 10% of your total — not zero.

Passive Voice Best Practices

• Target under 10% passive sentences for web copy, blog posts, and marketing pages.
• Keep most sentences under 20–25 words so passive constructions do not compound length problems.
• Edit in two passes: one for passive voice, one for sentence length. Fixing one often fixes the other.
• Read flagged sentences aloud — if you stumble, your reader will too.
• Leave intentional passives in place when the actor truly does not matter.
