5+ Best Passive Voice Checker Tools for Flawless Writing [2024]

passive voice checker

Key Takeaways:

Based on my own research and experience, the program that found and corrected (automatically!) my passive voice sentences the best was Grammarly Premium (the paid version – the free version won’t find passive voice sentences).

The best free passive voice finder was ProWritingAid – it was surprisingly good at finding these sentences and even providing suggestions for fixing them! Both of these programs are great choices for writers looking to improve their work!

Writing can be challenging, whether you write novels, short stories, screenplays, audiobooks, blogs, or anything else! You have to worry about grammar, punctuation, and making your point in a way that is interesting and engaging for your reader.

As a screenwriter and novelist, one lesson I learned early on while working on my first short screenplay, Devil’s Due, was to always write in the present tense. It’s a must in screenwriting and encouraged in creative writing.

The idea is to keep your characters and settings in the here and now, in the most dynamic way possible. And as a story coach and teacher, the one mistake I see over and over is writing in a passive voice.

But what if there was an easy way to ensure your writing was always on point? Passive voice checker tools can help identify passive sentences and make corrections. They are a great way to help make your writing clear and interesting for your readers.

To help you with this, I did a ton of research on these tools, and I tried each of them out with the same sentences. Read on to see how each of the programs did with finding my passive voice sentences – and which ones actually provided the fixes for the sentences!

What Is the Best Passive Voice Checker?

Many passive voice checkers are available online, but which is the best?

To answer this question, you need to understand what passive voice is and how it can impact writing.

Passive voice occurs when the subject of a sentence is acted upon by the verb rather than performing the action itself. For example, “The ball was thrown by John” is in passive voice, while “John threw the ball” is in active voice.

While there are times when passive voice can be used effectively, it is generally considered to be weaker and less direct than active voice.

As a result, an excellent passive voice checker should be able to identify sentences in passive voice and suggest revisions.

There are several different factors to consider when choosing a grammar checker:

  • The most important consideration is accuracy – you want to be sure that the checker will correctly identify (almost all) instances of passive voice.
  • Second, consider the level of precision you need. Some checkers will just highlight instances of passive voice, while others will provide more detailed information about why each instance is problematic.
  • In addition, some passive-voice detectors will give options for active sentences that you could use – many simply require a single click, and your passive-voice sentence is turned into an active-voice sentence automatically! These are my favorites!
  • Another consideration is user-friendliness – you want to be sure that the checker is easy to use and understand.
  • Finally, you will also want to consider the cost – while many passive voice checkers are free, some come with a price tag.

How I Evaluated Each Checking Tool

To check the accuracy and features of each tool, I used the same passive-voice loaded paragraph in each one:

“A cloud was seen by Sarah. A new car will be bought by me. The lamp was knocked over by the cat. The plates were being washed by Karen when I got home. Pretzels will be sold at the game. The teacher will be talked to about this by the principal. The truth will be uncovered eventually. You will be rewarded for your exemplary behavior. We have been practicing our instruments for hours. The dog was being walked by Tim when he saw the squirrel.”

1. Grammarly

Grammarly is a great online passive voice checker that can help you improve your writing by identifying and correcting instances of passive voice. Not only does Grammarly catch grammatical errors that you might miss, but it also provides helpful explanations so that you can learn from your mistakes and improve your writing skills overall.

Top Features

Catching all passive voice errors can be challenging when editing your work. An artificial intelligence tool like Grammarly can be invaluable in catching errors you might otherwise miss.

  • Grammarly will highlight your passive voice errors and show you how to correct them.

  • However, you need Grammarly Premium to use the passive voice checker (it’s not included in the free version, unfortunately!).


Grammarly Plans and Pricing

While the free version of Grammarly will help you fix spelling mistakes, punctuation, and other simple grammatical errors, you will need the paid plan to check for the passive voice in your writing.

My Experience & Bottom Line

When I added my passive-voice-laden paragraph to my paid version of Grammarly, it found seven passive-voice sentences immediately.

Grammarly suggested new, active-voice constructions for four of the sentences, and I could click and change those sentences to better ones (see the paragraph below – four of the sentences have been fixed).

But, unfortunately, Grammarly did not provide quick re-writes for the three other sentences it found. It told me that they used the passive voice and should be rewritten, but it did not provide a one-click suggestion (see below).

What Are Passive Voice Checker Tools?

Passive voice checkers are tools that help you make your writing better and clearer. They look for places where you’ve used passive voice. Passive voice is when something is done to the subject of the sentence, instead of the subject doing the action. This can make sentences sound confusing or awkward.

For example, in the sentence “The ball was caught by John,” it sounds like the ball is the main focus, not John. This makes it a bit weird to read.

These tools are great because they not only find these tricky sentences but also help you fix them. They can suggest ways to write in an active voice, where the subject of the sentence is doing the action. This makes your writing clearer and more fun to read.

They’re useful for all kinds of writing, like school projects or stories. Plus, they often check your grammar and spelling too. By using these tools, you can make sure your writing is easy to understand and enjoyable for everyone.

Final Thoughts

Whether you’re a writer looking to improve the quality of your writing or want to ensure you’re not using too many passive voice sentences in your work, the best passive voice checkers can help.

I definitely recommend trying out one of these tools (especially the free ones, like ProWrirting Aid) to help you easily and quickly identify any potential problems with your writing and make the necessary corrections.

Happy active-voice writing!

Common Questions (FAQs)

How do you identify passive voice?

To identify passive voice, look for a sentence construction that includes a form of the verb “to be” followed by a past participle. For example, “The ball was thrown by Mark.” In this sentence, the subject (the ball) is being acted upon (thrown) by the object (Mark).
To change the passive form of a sentence into the active form, reverse the order of the subject and object. In the example sentence, this would give you “Mark threw the ball.” You can also add details to active voice sentences to make them more interesting, such as “Mark threw the ball across the room.”

Does Grammarly detect passive voice?

Yes, Grammarly detects passive voice sentence construction – but only in the paid premium version!

How do you check if a sentence is active or passive?

To determine whether a sentence is active or passive, you must pay close attention to the verbs. In an active sentence, the subject is doing the verb. For example, “I am writing a paper.” In a passive sentence, the subject is acted upon by the verb. For example, “The paper is being written by me.”

What is the easiest way to correct passive voice?

The best way to fix passive voice is to switch the order of the subject and the verb in a sentence. In active voice, the subject is performing the action of the verb. For example, “The ball was hit by John” is in passive voice. This can be rewritten as “John hit the ball.”

What is a passive voice misuse checker?

A passive voice misuse checker is a digital assistant designed to enhance your writing skills and sentence construction. These tools specializes in spotting passive voice usage, which, while not grammatically incorrect, is generally accepted to make your writing less engaging and more difficult to follow. By using an online passive voice checker, you can easily identify and modify these instances in your writing, transforming your sentences into more direct expressions.

Why is a passive voice-checking tool important for screenwriters and playwrights?

Screenwriters and playwrights need to write their scrips in the present tense, so a passive voice-checking tool is essential for their writing process. The passive voice can make writing sound stilted and awkward. The tool will help you identify instances of the passive voice in your writing so you can revise them. If you’re a screenwriter or playwright, be sure to invest in an excellent passive voice-checking tool and great screenwriting software!
