Best Grammar Checker

Contributor, Benzinga

Nothing makes you or your business sound unprofessional quite like typos and grammatical errors. Yet, not everyone is an editor or has the budget to hire a proofreader.

That’s where using the best grammar checker can help you avoid errors and look professional. Not only that, but many checkers also help improve the readability of your content, which is beneficial for SEO, and helps add clarity to your writing.

We’ll review what makes for a great grammar checker and the benefits of using one.

What are the Benefits of a Grammar Checker?

Using an online grammar checker either for personal or business use has many benefits. Here’s a look at some of the reasons you should consider using one.


While you shouldn’t solely rely on a grammar checker to proofread your work, it creates a great starting point. This reduces the time you spend proofreading your work. Instead of worrying about the correctness of the content, you can focus more on making your writing sound great during proofreading.

Learn Grammar Rules

You probably don’t realize that you make the same grammar mistakes over and over again unless someone points it out to you. Using a checker can help you learn your writing weaknesses to improve your skills and avoid making common mistakes.

Improve the Professionalism of Your Writing

Grammar checkers catch spelling errors, misused words and sentences that lack clarity. All these functions will improve the professionalism of your writing so that you always present yourself well. This is great for students, working professionals and even professional writers. 

Better Readability for SEO

If you’re writing online content, SEO is probably a huge consideration for you. Keywords are certainly an important part of optimization, but so is readability. The best online grammar checker helps improve readability with less complex vocabulary, simpler sentence structures and removing jargon from your writing.

What Factors Make a Good Grammar Checker?

If you’re wondering what is the best grammar checker, you’ll need to evaluate your needs first. The type of writing you do and how you want the grammar checker to integrate with your various software programs will be huge factors in finding the right service for you. 

But regardless of how you’ll be using the service, several factors will be important. Here’s a look at the 5 crucial things to consider as you shop around.

Availability of Different Types of Language

Some grammar checkers are multilingual, meaning you can write in many languages and check your content for accuracy. This can be helpful for global companies or people who regularly write in different languages. 

Fast results

Some services add an extension to your computer or phone to show you results in real-time. That means you don’t have to add a step to your writing process. While drafting emails, messages through your web browser, PowerPoint presentations and more, you’ll see fast results to correct your grammar as you go.


Anytime you download software or use an online service, you need peace of mind knowing that it doesn’t open you up to hacks or malware. Plus, your writing is your intellectual property so you need to protect it. Review how the checker encrypts data to check the security the service offers.

Ease of use

No matter how great the benefits of a service are, you probably won’t use it if it isn’t simple. You don’t need another step to do when writing so the more integrated the software is the better. Look for a grammar tool that integrates with the programs you use regularly.

Good UI/UX

The user interface is important to make the service enjoyable to use. Grouping similar grammar issues to show you areas you need to improve can help you learn while improving your writing. Some people want popups to alert about grammar issues while others want to run a check so that they aren’t interrupted while writing. Look for a user experience that matches how you write and proofread your content.
