What are the Benefits of a Grammar Checker?

A grammar checker primarily ensures the correctness of your content. Aside from grammatical correctness, here are a few more benefits of a grammar checker.

Saves time

While dictionaries may be the most reliable tool for the holy trinity of writing – vocabulary, spelling and grammar – most of us seldom have the time to sift through pages (or apps) for each word structure and correct usage. Grammar checkers automate the processes of corrections, saving you a lot of time. 

Professional Grammar Correction 

One of the core benefits of a grammar checker is to assist you in minimizing or eliminating grammatical errors. Grammar checking tools scan your contents for errors and suggest necessary changes. By using a grammar checking tool, you can create professional and error-free content.

Spelling Corrections 

On top of checking grammar, grammar checker tools also review spelling mistakes in your writing. It displays every spelling mistake you’ve made in your content and suggests the correct spelling. It’s an excellent way to improve the quality of your writing, as well as your language skills.

Plagiarism Check

Plagiarism can be a killer when it comes to credibility and search engine ranking. By making sure your content is original and engaging, you gain trust from your readers and establish authority in your field of expertise. Many grammar checker tools offer plagiarism checking that can be helpful if you are trying to establish your brand authority.

What Factors Make a Good Free Grammar Checker?

You can find hundreds if not thousands of free grammar checker tools on the internet. But do the tools of your choice have the following features? Be sure any grammar checker you use meets the following criteria.

Ease of Use

Choose a free grammar checker that is easy to use. If you have to spend more time getting from point A to point B through the tool, you’ll end up losing productive time. Try to make sure that the tool that you are using is comfortable and straightforward.

Fast Results

A lot of the tools available on the market respond slow to the changes in your writing. Spending more than a few seconds to get a writing suggestion can be counterproductive. If you have to spend more time getting suggestions from your tool, it’s probably a good idea to switch to a new option. 


Security should be a key concern when using a grammar checker. Many grammar checking tools available online are infamous for holding your data and using it as they please. 

It’s better to go through the tool’s privacy policy to confirm it is not leaking or misusing your data. Always stick with the tool that respects your privacy.

Multi-Language Support

Even the popular grammar checking tools are limited when it comes to language support. It makes more sense to have a tool that can work across multiple languages in a connected world. A grammar checking tool that supports multiple languages can help you gain extra miles.
