(Learn more about the human brain vs the computer over here.)
2. Although most abovementioned online grammar checker tools are free to use, some may have premium plans that offer other tools such as plagiarism checkers, synonym finders, etc.
3. Some grammar and punctuation checkers lack abilities such as checking apostrophes, comma checking, and quotation mark implementation in proper places correctly.

Best Online Grammar and Punctuation Checker Tools

Grammarly

10 Million users can’t be wrong

Grammarly has become my go-to grammar checker tool for over four years now. Business professionals, college teachers, university lecturers, bloggers, students, and even professional writers use this powerful grammar corrector tool to make error-free articles.

As a comprehensive grammar and punctuation checker, Grammarly has all the tools you need to correct any English document, which is not just limited to essays, assignments, campus projects, college lectures, legal documents, and business letters​.

You can check ANY set of English words on Grammarly and let it correct it for you.

Check out this introduction video of Grammarly to know more about it.

Among Grammarly’s sophisticated features, I have found a few key features. Here are some of them.

Key features:

• Grammarly Can Correct Over 250 Simple and Advanced Grammar and Punctuation Errors: Grammarly tool automatically scans your text/article and detects any sentence with poor grammar and punctuation marks. You are just a few clicks away from correcting them all. It is as simple as ABC!

• Check Grammar on the web, Microsoft Word, Google Docs and mobile: Grammarly provides all the facilities to check grammatical errors on your writings in all places.
• Check for Content Plagiarism: If you are a blogger just like me, you would know the Google Panda update pretty well. It is a nightmare for websites that have thin and duplicate content. But, what most threatens me as a website owner is what if Google identified my blog posts have duplicate content, even though I haven’t copied a single line of the sentence. Yes, it happens all the time for people. A plagiarism checker tool is the best way to find out what percentage of your blog article is plagiarised and what content they are. Grammarly has an in-built plagiarism checker tool that checks your dropped content against over 8 billion web page content.

• English grammar check: With the ability to test over 250 English punctuation and vocabulary errors, you can quickly turn your errorful article into an error-free one. In General, it takes about 5-15 minutes to correct all grammar mistakes in an article with 2,500 words. Yes, it ultimately depends on your writing style and the number of errors. But, unlike other grammar corrector tools, Grammarly can correct all grammar mistakes quicker. As Google measures your article’s quality by checking grammar and punctuation errors, you should ensure that your article is errorless, even if you’re a freelance writer.
• Vocabulary Enhancement: This feature is especially very useful for content marketers, bloggers, webmasters, and especially SEOs. Integrating synonyms in your content will improve the quality of your article and its readability. There are millions of words in the English language. But, all of us, as ordinary people, know just a fraction of it. Grammarly finds relevant synonyms for your article according to contextual meaning and suggests them for you. Although you can use custom synonym finder tools, Grammarly is a better shot as it could save hours from your life.

Grammarly can be used as an online tool and software that works on your PC, tablet, or laptop. There are no differences between these two methods. I have used them – They are simply perfect!

Grammarly includes Android and iOS apps for checking grammar and punctuation on mobile devices (Grammarly Keyboard app). So, once you have created your Grammarly account, you can download Android App from Play Store and iOS App from App Store and use them with your smart device.

Furthermore, Grammarly does provide specific features under its “Business plan.” Brand Tons, Snippets, and Analytics are some of them. Learn more.

Grammarly does have two plans: Free and Premium. Find differences from this article.

Although there are many alternatives to Grammarly, Grammarly is far ahead of them in terms of features, accuracy, efficacy, and user-friendliness. Also, you can cancel your Grammarly subscription anytime if you are not satisfied with the service.

Final Words

As humans, we do lots of flaws. Even if you are a professional writer, poet, author, online school owner, online course creator, micro job worker, or freelance worker, you could make many grammatical and spelling errors.

You can fix those errors with the help of a very good proofreading tool.

But, what’s even worse is when your article doesn’t have punctuation marks in the proper places. One comma mistake can make a big difference.

Let’s eat grandma! Let’s eat, grandma!

Even though you can use a grammar-checking service, it will cost you a few hundred dollars for an article. And to get a paper proofread would take a significant amount of time.

As you need a quick solution for your grammar and punctuation mistakes, using an accurate, robust grammar and punctuation checker tool is best.

I use Grammarly’s Premium version. It checks my grammar and punctuation. Analyzes the text and fixes my grammar mistakes quickly.

If I didn’t use a punctuation checker tool for this article, I wonder if you could understand the text I wrote!
