Understanding Passive Voice vs Active Voice

Before discussing passive voice checkers, first you must understand what passive voice is. Passive voice isn’t always a grammatical error, but it is weak writing.

The best passive voice checkers

When you write in passive voice, the subject of the sentence is not the thing that does the action. For instance:

The store was opened by the manager.

In this sentence, the manager opens the store, but store is the subject of the sentence. Ot improve readability, it should read:

The manager opened the store.

This sentence is clearer and uses fewer words, making it a better sentence. The subject is the doer of the action, so it is in active voice.

How to Spot Passive Voice

Passive voice is appropriate sometimes, but overuse of passive voice is a grammatical error. Unfortunately, spell checkers and grammar checkers in Microsoft Word and other popular word processing programs don’t check for this problem. Writers have to learn to spot the passive form of the verb on their own.

Passive voice has the object of the verb as the subject of the sentence. It pairs an auxiliary verb, such as has or was, with the past participle. If you see an auxiliary verb with a past tense verb, chances are you have a passive voice sentence.

Spotting passive voice is sometimes difficult. Helping verbs do not always indicate passive voice. For instance:

She is going to help her sister clean her room.

In this sentence, the verb is future tense, not passive, and the helping verb is necessary to make the sentence clear.

Thankfully, you can find a number of helps out here with grammar checkers that also serve as passive voice checkers. Here are the top options to consider.

1. ProWritingAid


ProWritingAid has a free version and premium version, and both check for passive voice. This passive corrector not only finds and highlights the passive voice usage in your writing, but also gives you one-click corrections. Simply hover over the problematic sentence and click the better choice of the several it offers, and you have fixed your problem.

I used ProWritingAid regularly to check book chapters for instances of the passive voice in my Scrivener projects..

2. Grammarly

Grammarly’s free version doesn’t check for passive voice construction, but its paid version does. The paid version of Grammarly is so powerful that writers of the English language should consider it. If you use passive voice, the tool will highlight it and suggest that you change it, but it won’t give you suggestions that fit your sentence.

Grammarly can stay on at all times. It will scan text boxes on any site you’re working in, giving suggestions and helping with your proofreading. You can also upload content to the Grammarly site to check for grammatical errors and writing style problems, if you wish.

Grammarly proved more accurate than the below tools. Read our full Grammarly review.

3. Hemingway App

If you need a truly free passive voice checker, Hemingway App is the best choice, hands-down. It costs nothing and highlights and counts your passive voice sentences. Scan through the document to find all of the highlighted passive voice construction, and change it.

To use the Hemingway App, you must copy your content into the tool on the website. This extra step is worthwhile if you need a free tool, though, so don’t overlook it.  

Hemingway App offers more than just finding instances of passive voice, too. It will give you suggestions to avoid wordy sentences and improve the readability of your piece by improving your writing style.

4. WhiteSmoke

WhiteSmoke provides a grammar and passive voice checker that’s compatible with many devices, including Microsoft Word and the rest of the Microsoft Office suite. Not only does it check grammar and reduce passive voice overuse, but it also helps you translate your content into other languages, which helps for international writing.

What makes WhiteSmoke stand out is not just its passive voice checker. It also has video and written lessons to help make you a stronger writer.  

Like many tools, WhiteSmoke highlights grammatical errors with color-coded messages that help you spot the type of mistake you made. For instance, the app highlights spelling mistakes in red while writing style issues have a different color.  However, the app lacks many of Grammarly and ProWritingAid's reports.

5. Ginger

Ginger is a language translation tool and grammar checking program. It has 55 languages in the paid version and 40 in the free version, giving you tools to write for international audiences. However, it’s also a reasonable English language grammar checking tool.

With Ginger’s Sentence Rephraser tool, you can find passive voice construction and get suggestions on how to rewrite it to make the subject the doer of the action. Ginger offers desktop and browser extensions to help improve the quality of your writing automatically. However, it is not a free tool.

Ginger is also difficult to use and lacks many of the features that ProWritingAid and Grammarly posses. Read our Ginger review.

Why You Can Trust Us

I've published several books on writing and contributed to publications like Forbes. I tested these writing tools extensively using blocks of text of approximately 100-200 words in length for a non-fiction article.

I pasted the text into each one of these tools and evaluated the recommendations in terms of accuracy and easy of use. Currently, I use ProWritingAid and Grammarly the most due to speed and accuracy.

Combine a passive voice checker with a high-quality grammar checker, and you will be able to tighten up your writing and make it more effective at communicating your message.

In short: use either Grammarly or ProWritingAid.

FAQs About Passive Voice Checkers

Why should writers check for passive voice?

Passive voice construction makes writing less clear and more wordy. Writers, especially those writing for online audiences, need to have a strong focus on readability. Using a passive voice checker will eliminate wordiness and make writing easier to read.

Can a passive voice checker eliminate the need to proofread?

No, because passive voice checkers and grammar checkers use artificial intelligence to check writing, and that is no substitute for a final proofreading of your document. Use the tools, then use your own proofreading to ensure everything is clear, concise and easy-to-understand.
