So, don’t feel alone if you are struggling to improve your grammar skills. There are several people like you and me who are on the same footing. And in this article, I shall share 8 Best Grammar Checking Software which will definitely help you to overcome your writer’s block.

The best part of our modern world is that there are hundreds of solutions for a single problem. The same is true with grammar checkers. While none of them is completely accurate, some are definitely better than others. Moreover, the price also varies. So, I have arranged them according to my favorite.

Here Is My List of 8 Best Grammar Checkers

  1. ProWritingAid
  2. Grammarly
  3. WhiteSmoke
  4. GradeProof
  5. WordRake
  6. StyleWriter
  7. SlickWrite
  8. LanguageTool

How Did I Choose These Grammar Checkers?

When there are several grammar checkers available in the market choosing the best among them is not very easy. Sometimes, it depends on personal preferences also. So while choosing the best grammar checkers, I have kept two main points in mind.

First and foremost criterion is their accuracy. If it is not accurate then there is no point of mentioning them in this list. I have not included Ginger Software, and Hemingway here in this list as I have already mentioned them in my previous post. Moreover, AutoCrit, and Scrivener are more than just grammar checkers and they target very different users. I have not mentioned them here.

Secondly, their price. While most of these software are subscription-based, there are few which provide free online checking facility also. However, if you are using these tools for your professional work, it is always better to avoid such free service. Moreover, paying a hefty bill without any return is meaningless. So, I tried to maintain a balance between the quality and their price.

1. ProWritingAid

ProWritingAid is undoubtedly one of the best grammar checkers available today. It not only checks your writing for Spelling Mistakes and Inconsistent Grammar but also provides Style Suggestions and Plagiarism reports.

I have extensively used this grammar checking tool and found it very useful.

ProWritingAid checks for more than 350 different grammar rules, overused words, cliches, redundancies, transition between sentences and several other writing mistakes. Realtime analysis constantly scans your article and provides improvement suggestions.

It has a huge database of contextual vocabulary which makes it almost impossible to pass any writing mistakes unchecked. When it comes to writing essays and other long articles, ProWritingAid probably provides the best all-in-one solutions in the market.

However, this tool does not perform very well for writing snippets. So, if you are writing casual comments on your Facebook post, you may not get very good suggestions from this tool.

Browser support for Google Chrome, Firefox, Microsoft Edge, and Safari makes it almost omnipresent. Other than browser extensions, it has dedicated desktop apps for both Windows and Mac OS. You can also use it as a plugin for Microsoft Office, Scrivener, and several other productivity tools.

So, if you are a blogger, a writer, or a student it could be your ideal writing companion.

ProWritingAid has both free and paid subscription plans. While the free version is limited to 500 words, the premium plan lets you edit unlimited words.

The best part is that unlike any other tools you can test their premium service free for 30 days. Upgrade only if you like their service. As an affiliate partner, I offer an exclusive 50% discount for my readers. You can click the button below to avail the offer.
