5/5 (4)

Are you looking for a reliable passive voice checker?

That’s an excellent idea. You should always avoid using the passive voice in writing as much as you can.

But sometimes it isn’t easy to spot when you are doing a quick proofread of your text.

A much easier, and more accurate way to locate a passive sentence or passive construction is to use an online checker.

There are many free online tools you can use to help you. The bonus is that many of them will help you find other grammar errors and spelling mistakes as well.

The best tools will give you options or examples to change a phrase written in the passive voice to the active voice.

But before I get to my list of useful tools, it worth understanding the difference between active and passive voice.


What is the passive voice?

It is when the subject of the sentence is not performing the action.

The structure and the form of the verbs are to be plus the past participle. It can also use the verbs to have and to get in the causative form.

With passive voice sentences, we don’t know who is performing the action unless we add an operator.

For example, in the passive voice, the subject is usually a thing and not a person.


This house was built in 1970.
We don’t know who built the house because the house receives the action of the verb.

This house was built in 1970 by John.
Now we know who built the house because John is the operator. But this house, the sentence subject, is acted upon by the passive verb.


But if we change to the active voice, the subject is a person, and the sentence is much easier to understand.


John built this house in 1970.
Now it is clear who built the house.


In the English language, writing active sentences is always the best option. You should use the active form in articles, fiction, blog posts and any form of messaging, email or general correspondence.

However, in business and scientific writing, the passive is used a little more frequently.

It is because there may be a need not to say who did something or to apportion blame. A prepositional phrase is often used to introduce a topic.

In reply to your complaint, your delivery was delayed due to unforeseen circumstance.


In the causative form, which is sometimes called the have or get something done form, again we don’t know who performs the action.

I really need to have my car serviced.

Joe has to get his hair cut before his interview.

You should have your blood pressure checked.

Are you going to get your computer repaired?


In the examples above, we don’t know who is performing the action.

To re-write these sentences in the active form, we need to include a subject that is performing the action.

I really need to have the garage service my car.

Joe has to get the barber to cut his hair before his interview.

You should have your doctor check your blood pressure.

Are you going to get Apple to repair your computer?
