Grammar Check VS QuillBot: Which Can Check Grammar Better?

Grammar errors are a very common thing in writing. It is not only faced by newbie writers but also professional/experienced writers also face this issue.

Sometimes, they spell incorrectly, forget to add the punctuation mark, or make wrong use of the subject-verb agreement.

However, finding these minor errors manually can be a time-consuming task. But do not worry. There is another way to do that.

There are hundreds of grammar checkers available on the internet that can help to find and correct grammatical errors in the text but finding a good tool can be a tedious task.

So, in today’s article, we are going to review two best grammar checkers. One is Grammar Check, and the other is QuillBot. We will compare both of these tools and see which can check grammar better.

Grammar Check

Grammar Check is an online tool that uses a combination of Natural Language Processing (NLP) and Artificial Intelligence (AI). It is a free online grammar tool that works very effectively to find any type of error, such as grammar, punctuation, and spelling errors.

Besides, this AI grammar checker also provides some very unique features, like you can import the text file and correct grammar errors in the text. Along with this, you can also download the file in DOC format.

So, this was the quick overview of Grammar Check. Now, let us see what QuillBot is.


QuillBot is an online platform, which provides different tools for its users, and its Grammar Checker is one of them.

Quillbot’s grammar checker is also an online tool that utilizes AI and NLP to find and correct errors. It is a free tool that allows users to check grammar errors in lengthy files, too, just like in Grammar Check.

Besides, in QuillBot, there is a real-time text editor where users can type the text and make changes in the text, like bold or text alignment.

Now, let us compare both grammar checkers and see which one is best.

Features Comparison: Grammar Check VS QuillBot

Here we will explore each of their features and see which one is best.

1.    Import Options provides multiple importing options like users can import the text file from device storage. Also, they can copy/paste the text and check for grammatical errors in the text. Users can import the text file in .doc, .docx, or .txt format.


On the other hand, in QuillBot, you can only copy/paste the text and check grammar errors. There is no file import option available in the QuillBot, like available in the

So, in this feature, Grammar Check got the point.

2.    Multilingual

If we talk about how many languages are supported in both tools, then in Grammar Check, there are five different languages supported, which are:

  • English
  • Spanish
  • French
  • Italian
  • Dutch

On the other hand, in QuillBot, there are only four different languages are supported, which are:

  • English (US)
  • German
  • French
  • Spanish

This means users can check grammatical errors in the following language text.

So, in this feature, too, Grammar Check got the lead.

3.    Context Analysis

Now, this (output results comparison) is the most important point for everyone who wants to use them.

As you know, Grammar Check uses highly advanced AI-based algorithms in which they can easily and clearly understand the text.

Not only that, while doing this, it also provides the right and correct words that can be replaced instead of incorrect ones to eliminate grammatical errors.

If you notice in the below image, you will see that Grammar Check has provided two different correct choices, and both of them are correct.


But, on the other hand, if you notice the QuillBot, it did not provide the right word that can be replaced.

This means QuillBot AI did not understand the context of the text and provided a h. The result is shown in the below image.


So, this was the major issue, and here also, Grammar Check got the point.

4.    Mobile and Desktop Applications

This factor is also considered one of the most important ones when choosing the right tool. As you know, sometimes the writer does not have their laptop with them, and if they want to check grammar mistakes in their blog, they cannot do that.

So, while keeping this issue, Grammar Check has provided a free application for mobile and desktop users.

Mobile users, whether they are using iOS or Android OS, can download the application from their respective mobile stores. Similarly, for Windows or Linux users, they can download the desktop application from their store.


However, QuillBot does not provide mobile or desktop applications for users’ ease. They only provide the Chrome Extension, which is available for free and can be installed only on Google Chrome.


This point also goes to Grammar Check.

So… Which One Can Check Grammar Better? – Conclusion

After reviewing both of the grammar checkers, we have come to the final verdict that Grammar Check is the one that wins this comparison.

As you see above, we have discussed some major issues in both tools and shed light on them. We have also attached screenshots for the proofs.

You can clearly see that in the Context Analysis feature, Grammar Check has provided the correct word suggestion to replace it with the incorrect one.

But, in QuillBot, it has provided the wrong suggestion because it fails to understand the context.

Not only that, but also got the lead from QuillBot in the language-supported feature.

So, you can get a clear idea of which one is better and detect grammar errors.


You should also give it a try.
