What’s The Best Grammar Checker To Correct Your Writing?

The Best Grammar Checker

No matter what you write, you always need to check your text for spelling and grammar mistakes.

But it is not as simple as thinking that a quick basic spell check in Microsoft Word is going to result in error-free writing.

Whether you are an author, content writer, blogger or social media marketer, writing errors are a fact of life.

That’s why we have editors and proofreaders, or at least someone else to read and check. But they are not always available for everything we write.



Quality writing at all times

We all live and work online so much now. Our writing quality is challenged whenever we sit down at a keyboard. That’s why we all use an online grammar check in some form to help us write more accurately.

How bad does it look when your business is online writing, and you make clumsy spelling mistakes in a Facebook post?

Well, at least there is the possibility to go back and edit your post if you notice the mistake.

But what if you post a comment on a blog or newspaper with a little punctuation or grammar error?

There is no turning back once you have completed your comment in the text box and clicked send. Your silly little error will live on forever.

As a writer, you have to continually check for grammar, spelling and punctuation mistakes.

When you have good grammar corrector, it will check your writing so you can decide on the appropriate corrections before you publish online.


I need writing help

An online grammar checker tool is a necessity

Your writing skills are not in question.

But working online places pressure on all writers and it is so easy to make small grammatical errors.

It’s fast-paced, and every word you write is instantly read by a lot of people. Some are very quick to criticise too.

No matter what or how you write, you have probably tried many free online tools. You want to check your spelling, grammar, sentence structure, run-on sentences or even your writing grade level and accidental plagiarism.

Over the years I have tried a long list of grammar checkers both free and paid.


Most of them worked reasonably well, and it is hard to complain about apps that are completely free.

I found that I could mix and match these tools when I needed them.

So I had my favourite free spell checker, grammar checker, plagiarism checking tool, Flesch–Kincaid readability checker and context spelling error checker.


My bookmarks grew very long with online English language correction tools

Of course, using my long list of favourite free writing correction tools had one serious drawback. I had to go to each site and paste my text over and over again to do each one of the checks.

I had a few free Chrome extension tools as well. So it got very complicated going to one app to check verb agreement and another to check sentence or passive structure.

I needed a better solution than a bundle of free grammar checkers.

That’s when I started to do my research for a better way to manage my online writing. I looked seriously at what more efficient solutions were available to replace all my free grammar checker tools.

In the end, I narrowed down my list of premium grammar and spell checkers to Whitesmoke, ProWritingAid, Ginger Grammar and the Grammarly tool.

Then I checked a lot of online reviews for each one and noted the strengths and weaknesses and of course, the price.

The biggest factors for me were accuracy, speed and flexibility. Price was important too but only in relation to what I got for my money.

After all my research, the only one that had everything I wanted was Grammarly. It was also rated at the fastest and most accurate. But I have to say, it certainly wasn’t the cheapest option I found.


Why did I choose Grammarly?

I’ll give you an idea in images to show you why I decided that it was the best grammar checker for me.

As I type this post in WordPress, I can use the Grammarly editor using a browser extension for Chrome, Safari or Firefox. I can also use it on my iPhone or iPad.

If I click out and return to my normal WordPress editor, Grammarly is still with me making suggestions. Here I am looking for a synonym.



Even when I use my SEO plugin to write a meta description, Grammarly is there.

If I get a bit lazy and sneak off to social media for a few minutes, Grammarly follows me to Facebook, Twitter and all the rest.




Grammarly works on any site I use and on top of being accurate, it is lightning fast. There is not a hint of hesitation when it suggests a correction.

For my first line of defence against making writing mistakes or grammatical errors online, it ticks all the boxes for me.


What about longer forms of writing?

Blog posts and social media posts are one thing, but long-form writing is another. This is when I get serious and use the Grammarly editor.

One of the big advantages is that you can set your preferred English. Not only American and British but also Canadian and Australian English.

The second is a great tool for fiction writers in particular. There is a personal dictionary, so you can add invented words or character names and be sure you get them right every time.

Before you start, you can set your writing preferences or what Grammarly call goals.

Now we are ready to do some heavy-duty checking and correction with the Grammarly Editor.

On the left of the editor screen, the text is displayed with suggested corrections underlined. On the right is a summary of errors that should be checked.

You can click on any underlined area to make a correction within the text.

There is a pop-up box for each error or suggestion. When you click, it gives you examples, explanations and alternatives.

When checking a long document such as a book chapter, it is easy to see where possible problems lie and work on making your corrections.

Out of all the grammar checker tools I have used, this is by far the most user-friendly, fastest and most accurate.

As I use a Mac, I upload my Word files to the editor and then download the corrected files without any loss of formatting. It works perfectly.

But if you have a PC and use Windows, there is a Grammarly plugin for Microsoft Word so you can work directly in Word.

You can also use it with Google Docs. I have my fingers crossed that this functionality will come to Office for Mac, but it’s not a big issue for me.

One other check that you can do in the editor is to search for any plagiarism occurrences in your text.

Some other checkers charge you extra for this feature. But it is included with Grammarly premium.

The example document I used in the editor was for an old post I wrote for Medium. As you can see, the plagiarism checker found the text online. The test took only a few seconds, so it is extremely fast.

One other very useful tool is the Insights report. Here you can see a summary of your text as well as a Flesch–Kincaid readability grade.

I don’t go anywhere online without Grammarly

I have been using Grammarly for over three years now. I can honestly say that it is by far the best all-round English grammar checker, spelling and plagiarism checker.

Not only does it have every writing correction tool I need. But it is also fast, reliable, accurate and importantly, unobtrusive.

Grammarly is an app that works wherever you write.

There is a free version of Grammarly, which works quite well and will suit students. It is also a great free tool if English is not your mother tongue, or you are learning English.

But if you are serious about writing, I would highly recommend that you consider the Grammarly premium version.

For any type of writer, it’s the best grammar checker and writing insurance you can buy.

    The best Grammar Checker on the Mac is Grammarian PRO2. It’s made for the Mac by Linguisoft. Anything else uses manual copy/paste ans destroys character formatting.

    With ProWriteAid and Grammarly going head to head, what are the advantages of one over the other? I use the free version of Grammarly but have upgraded my ProWriteAid to a paid subscription. If there was a significant advantage of upgrading the Grammarly I would do it and not renew my ProWriteAid. Please help with the confusion.

      I use both premium versions. In a nutshell, Grammarly is much better for all-around online use. It works almost everywhere. ProWritingAid is better at editing long-form writing in its dedicated editor.

    I use Grammarly too, and agree wholeheartedly with every thing you say!
