Grammarly has been around for a while so we wanted to refresh our Grammarly review for 2020 to highlight new capabilities and features, especially in light of Microsoft launching their Microsoft Editor which is a very similar product. In this review, we’ll dive into what sets Grammarly apart and why you should consider it as your grammar checker.

First, let’s talk a little bit about what Grammarly is and why we find it so useful.

What Is Grammarly?

Grammarly is a free online grammar checker that lets you proofread articles, essays, emails, book chapters, and more for common grammar and spelling mistakes as well as typos. You can either write directly in their editor or upload documents you have written. There’s even a Google Chrome plugin that will edit documents and blog posts created outside of the Grammarly website. I used the plugin to edit this post! Hopefully this Grammarly review will convince you that Grammarly is an amazing tool.

They also offer a premium service that will uncover deeper grammatical issues and plagiarism detection.

I think you’ll agree with me when I say typos and grammar mistakes are embarrassing. Grammarly takes the guesswork out of proofreading.


Grammarly has a number of unique features that make it the best grammar checker on the market:

  • Grammar checking: It has a highly effective grammar checking feature that can greatly benefit writers and bloggers. It has very high accuracy which was quite surprising coming from an automated tool.
  • Integrates seamlessly with Google Chrome: One of the best features of Grammarly is that it works flawlessly with Google Chrome. Simply install the Grammarly Chrome plugin and start letting Grammarly correct your writing across the internet.
  • Proofreading: It can be used to proofread business cover letters and academic papers. It can also be used to edit a novel or a casual email. Proofreading comes free with Grammarly unlike other proofreading tools which are available in the market.
  • Plagiarism detector: Plagiarism checking is a premium feature of the application. It can successfully check more than eight billion web pages when it is used to make documents. This is good for making data both standard and unique.
  • Suggestions for vocabulary enhancement: The application has an excellent database of vocabulary. It gives suggestions to improve the usage of vocabulary as you type. This feature is useful for people who have the habit of repeating some words when preparing documents.
  • 150 critical spelling and grammar checks: Grammarly has an algorithm that is designed to check for over 150 critical grammar checks on documents. This feature is useful for people who are victims of making many mistakes during writing. Furthermore, it has a user interface that is both responsive and very simple to use. This is because Grammarly executes when the user begins writing and provides results when writing stops.

A Review of Grammarly’s Pros/Cons

Grammarly Pros

  • Integrates into Google Chrome so you don’t need to do anything else to get feedback.
  • Excellent grammar proofreading with an extensive online knowledgebase.
  • Extremely useful for non-English speakers.
  • Free version checks for over 100 different grammar rules (Premium does over 400).

Grammarly Cons

  • Grammarly Premium costs $29.95/mo ($11.66/mo for annual plan) which some users may balk at.
  • A proofreading is still necessary since Grammarly will not catch every mistake.

What Grammarly Checks For

Grammarly checks for three main things: grammar, spelling, and vocabulary.

  • Grammar: Grammarly checks your text for over 150 grammar rules (over 250 if you get Premium). It can check everything from subject-verb agreement to article use to modifier placement.
  • Spelling: Spell checkers have been around for a long time, but Grammarly takes spell checking to another level. Their algorithm spots erroneous use of lose/loose, affect/effect, lie/lay, there/their/they’re, and many other commonly confused words.
  • Vocabulary: In addition to the grammar and spell checking, Grammarly will also suggest synonyms that it thinks will make your writing more powerful by analyzing the content as you write.
  • Plagarism: One of Grammarly’s unique features is its ability to automatically check for plagiarism within your work so that you know immediately whether you need to include citations or redo the writing.

Is Grammarly Premium Worth It?

The Grammarly cost for a premium package is $29.95/month (or $11.66/month if you buy the annual package) which offers additional features you can’t find in the free version or the Grammarly Chrome plugin.

The features that are found in the premium version vs the free version can be seen in the table below:

150 critical grammar and spelling checks
250+ additional advanced grammar and spelling checksX
Vocabulary enhancement suggestionsX
Genre-specific writing style checksX
Plagiarism detector that checks more than 8 billion web pagesX

We do have a special offer to get 10% off of Grammarly Premium by going to this link.

Premium customers have even seen dramatic results over the free version:

  • 99% of students see improved writing grades
  • 76% of customers find writing more enjoyable
  • 85% of customers are stronger writers

Overall, the premium version offers some great features that definitely help people become better writers.

How to Use Grammarly to Check Grammar

Using Grammarly was a breeze. All I did was go to their website and create an account. I also added the Google Chrome plugin when I registered.

Once I had an account, using Grammarly was very natural. The interface is very similar to Google Docs.

When you first log in, you can either create a new document or upload an existing one.

Grammarly Review

Once you have created a new document you can click on it and be taken to the editor. I used two paragraphs from one of my other sites, Viola Central, as an example:

Grammarly Review - Demo of Post

As you can see from the image above, Grammarly does a great job of capturing the key errors. While it is not 100% (it says my use of the word “viola” might be incorrect and could possibly be “villa”), it certainly works well enough.

The interface is very similar when using the Google Chrome plugin. Grammarly will check for grammar errors and typos while you type, underlining words and phrases it thinks may have issues.

Testing Grammarly

In order to show you how powerful Grammarly’s algorithms are and prepare this Grammarly review, I have taken a sample poorly written paragraph from an English class website at Penn State University.

According to the PSU website, the paragraph has the circled four errors that were identified by human proofreaders:

Let’s see how Grammarly did:

Wow! Grammarly identified more errors than the human did and actually offered suggestions.

How Does Grammarly Compare With Competitors?

Grammarly vs Ginger

Grammarly’s closest competitor is Ginger Software. Like Grammarly, Ginger offers a Google Chrome and Microsoft Office plugin in addition to the online portal. They are also free. In fact, the offer plenty of options for which devices you can use Ginger on including: Windows app, iOS, Android, Chrome extension, Safari extension.

I personally prefer Grammarly’s online interface over Ginger’s. Grammarly immediately shows you the errors on the right-hand side of the screen whereas Ginger forces you to scroll over the word/phrase.

Grammarly vs Hemingway

Hemingway is another app that can be used for checking your writing. However, it does this in a different way than Grammarly. While Grammarly will point out specific grammar issues, Hemingway will focus on the bigger picture of your writing. Hemingway will give you feedback on whether sentences are hard to read and some general stats about your writing, such as how many adverbs you used, but it won’t give you much else. You are on your own to make the corrections it suggests.

We love Hemingway as a writing platform, but cannot recommend it as a good grammar checker.

Other Benefits of Grammarly

Grammarly boasts of providing consumers with a ton benefits including:

  • It has the potential of scanning for up to one hundred and fifty common and even advanced grammar rules. This is very good as it only shows its robustness and how thorough it is
  • It is designed to even check for plagiarism and go the extra mile to create references that it considers the text was lifted from
  • It has free online services i.e. community-driven forum, reference guide and a thesaurus

  • It allows people to utilize either UK or US standards
  • Its features are customizable
  • It can be used for by schools, businesses, and individuals

Final Words

After using Grammarly for the past month, I have come to love this grammar checker which is why I wanted to write this Grammarly review. As the example above proved, Grammarly actually performs better than a human proofreader in most cases. However, Grammarly does offer human proofreading in their Premium service at 2 cents per word for 24-hour turnaround.

Hopefully this Grammarly review proved why this free grammar checker is amazing. Here’s a quick recap:


  • Integrated within your browser so you don’t need to do anything else to get feedback
  • Excellent grammar proofreading with an extensive online knowledgebase
  • Extremely useful for non-English speakers
  • Free version checks for over 100 different grammar rules (Premium does up to 250)


  • Pro version costs $29.99/mo which some users may balk at
  • A proofreading is still necessary since Grammarly will not catch every mistake

Go ahead, give Grammarly a free try and see if you don’t feel the same as me! I hope this Grammarly review has convinced you.

  1. Grammarly is a keylogger which captures everything you type in your browser. Google steals other people’s work, such as the tens of millions of online translations that are aggregated every day in order to create the illusion of an AI translation service. I wrote this entire post without Grammarly and you can write on your own too.
