  • There’s more than one tool out there, so you can put your writing through various checks.
  • Thanks to developments in artificial intelligence (AI) technology, modern grammar tools are better than they were a decade ago, and they are constantly improving.

Cons of Using Passive Voice Checker Tools

That said, passive voice checker and corrector tools have their own cons. They include:

  • Software doesn’t always understand context – so it will end up flagging sentences that will otherwise not make sense if they are not in the passive voice.
  • Grammar tools have been known to provide questionable suggestions.
  • The more complex the grammar tool, the more it is to be likely expensive.
  • Passive voice checkers can never be a replacement for the human mind – these tools won’t help you much if you don’t have a good grasp of English grammar rules.

How To Spot Passive Voice

The apps we’ve discussed above will help you identify the passive voice in your texts. However, it is useful to know how to spot the passive voice so that you can avoid making the mistake as much as possible, even if have no passive voice checker handy.

Identifying the passive voice is simple. When you’re looking at a sentence, try to locate what happened and who did it.

For example:

Passive voice: The wall was painted by Maria.

What happened? The wall was painted.

Who did it? Maria.

If the person or thing responsible for the action comes after the verb, then it is a passive sentence. 

Look at the same sentence in active voice:

Active Voice: Maria painted the wall.

See the difference? In short, in a passive sentence, the subject is acted upon by the verb while in an active sentence, the subject is doing the verb.

See our comprehensive guide on Active Vs Passive Voice where we discussed these in detail, including several examples and worksheets to help you practice.

Should You Use Passive Voice In Writing?

You might be wondering, can I use the passive voice? Why is it such a big deal? Why do I have to avoid it?

Depending on the type of writing project and the purpose of your writing, there are certain instances where you should use the passive voice. Scenarios such as when reporting for news, academic writing, or creating suspense in storytelling. Otherwise, it is best to avoid using the passive voice altogether.

When you use the passive voice, your sentences might look vague. It creates emphasis on the action, rather than on the subject. This means your sentences may sound awkward, flat, or uninteresting.

See our guide on Passive voice in writing to learn more.

How Can You Use Passive Voice As A Writer Or Author?

Of course, that does not mean the passive voice is always a bad thing. There are some cases in which you can use the passive voice, and it’ll help your writing.

There are times when the passive voice works best to present an idea. It is especially used in some formal, professional, or legal instances.

Here are some examples and special cases when it is okay to use passive voice:

  • When reporting a crime with unknown perpetrators: My friend was assaulted yesterday.
  • In a scientific context: The drug was tested on human beings.
  • To emphasize an action and the doer is irrelevant: The president was sworn in last month.
