The best grammar checker

It’s no secret that English grammar can be tricky. For non-native speakers, it can often be difficult to determine which rules to follow and when to use them.

This is when a grammar checker comes in handy. These online tools can help you to improve your grammar skills by identifying grammar errors and spelling mistakes in your writing and correcting them right away.

Not all grammar checkers are equally reliable, however, so it is important to do your research before choosing one.

In this article, you will find a detailed list of the most reliable online grammar checkers in English. We will also discuss the different features that each grammar checker offers and how to choose the best one for your needs. Dive in!

Why Use a Grammar Checker?

There are several reasons why you might want to use a grammar checker. Perhaps you are writing an important email for work, and you want to make sure that it is error-free. Or, maybe you are working on an essay for school, and you want to ensure that it is well-written and free of any misspelled words or grammatical errors.

Whatever the reason, a grammar checker can be a valuable tool.

Using a grammar checker can also help you improve your writing skills. By identifying spelling and punctuation errors in your writing, you can learn from your mistakes and make sure that you do not make the same ones in your future assignments and other pieces of writing.

In addition, seeing corrections made to your writing can help to solidify the English grammar rules in your mind and improve your understanding of them.

What Factors to Consider When Choosing an Online Grammar Checker?

There are a number of different online grammar checkers available, so how do you choose the best one for your needs? In this section, we will discuss some of the factors you should consider when choosing an online grammar checker.


One of the most important factors to consider when choosing an online grammar checker is accuracy. You want to make sure that the grammar checker you choose can accurately identify grammar and spelling errors in your writing and make corrections as needed.

To determine how accurate a grammar checker is, you can read online reviews or try out the tool yourself on a piece of writing.

Note that some of the checkers will be able only to find typos and errors of grammatical nature, such as inconsistency in the subject-verb agreement. On the other hand, other tools will be able to catch mistakes like run-on sentences and comma splices, misused words, or even point out a poor choice of words.

It all depends on how well-developed an online editor is.

Ease of Use

It is also important to consider how easy the grammar checker is to use. Some grammar checkers are user-friendly and easy to navigate, while others can be more difficult or confusing to use.

If you are not tech-savvy, you might want to choose a grammar checker that is easy to use. Otherwise, you might find yourself frustrated with the tool.


When choosing an online grammar checker, you should consider the features that it offers. Some grammar checkers just identify errors, while others also provide explanations for why the errors were made and suggest corrections on how to fix them.

Some grammar checkers also have various additional features, such as a virtual writing coach or a plagiarism checker. You can even find grammar-checking tools that provide a browser extension. Determine which features are most important to you, and choose a grammar checker that offers them.


Pricing is another factor to consider when choosing an online grammar checker. Some grammar checkers are free to use, while others come with a subscription fee.

If you plan on using the grammar checker frequently, it might be worth paying for a subscription. However, if you only need to use it occasionally, a quick free English grammar check might be all you need.
