(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. That’s why we have ranked punctuation and grammar checker tools in a table so that you can understand the functionalities of each tool clearly.

Best Online Grammar and Punctuation Checker Tools

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 lettersโ€‹.

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

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.

Not putting dots, commas, and quotes in appropriate places of your email application could result in not approving your proposal and losing a valuable customer.

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!

  1. Cool post! I like grammark! But apart from grammar and punctuation checking, it is also worth checking for plagiarism. I use this tool , which is perfect for bloggers.

    • Yes, Jason, GramMark is a very good grammar checker tool. Thanks for sharing your favorite punctuation and grammatical checking tool.

  2. This is one of the best blog that I had ever seen this before. I just love your post. Now-a-days grammar is very important in the English language. I am using Nounplus(dot)net . It is a free Grammar checker. After using this I increased both my grammar and writing skill. Thanks for sharing with us such a wonderful post.

    • Yes Sae, i always use online grammar correction tools to fix my grammatical mistakes. It is very important as one incorrect word can change the meaning of entire article. I didn’t know about Nounplus grammar checker tool. Thanks for let me know about it.

  3. I enjoyed your article and agree with your conclusions. However, what I think you are really looking for is an ESL grammar checker. ESL is “English as a Second Language.” None of these websites target the kinds of errors second language speakers make. They are designed for American college students, not bloggers writing in their second language. I will give you an example from your own article. You wrote this:

    As humans, we do lots of flaws. Even you are a professional writer, poet, author or a freelance copywriter; you would make lots of grammatical and spelling errors. If I didnโ€™t use a punctuation checker tool for this article, I wonder if you could understand the text I wrote!

    There are at least 5 second language errors in these sentences that first language grammar checkers won’t catch. That’s why as an ESL teacher I always recommend a particular website which is not on your list. is the only free online ESL grammar checker that will catch second language errors that the other websites miss. Copy/paste the sentences above to see what I mean.

    Anyway, thanks for a great article and the useful lists of key features.

  4. I agree with Nicholas. Sorry to be mean Chamal but your advice on these sites would be stronger if your writing was not littered with basic errors. I have been managing large teams of people in India writing for a long time and found to my amazement that none of these programmes deal with the most common and basic errors normally found in Indglish writing. Try typing the sentence ‘The England is better than German army’ into them, which breaks basic rules of how to use articles. None of them pick it up. I don’t understand why these tools can’t pick up these basic issues, as well as more complex style issues, but they don’t, so I have given up on them. Nicholas catches the issue with ‘German army’ but not the problem with ‘the England’ which I think is pretty basic and fixable? I have entered a change request. If you are interested I am happy to test some more text with the typical errors we encounter. If we could remove even 75% automatically it would be a godsend.

    • Oliver, I also admit that my writings are not 100% correct. There are a few reasons for that.

      Yes, NOT any grammar checker tool can fix those common errors. That’s a reason why every programmed application can’t replace for man’s talent, skills.

    • Oliver, I got your suggestion for “the England” and added a rule to cover “the” + 164 countries to the You can check it. As for what you call “basic rules,” it is amazing the number of basic errors that a native speaking educated human can detect in English– but it takes that human 25 years to develop the ability. To get a computer to detect and correct just a fraction of them has taken me 4 years and 81000 lines of code. I develop the error detection rules for the VWT from the errors in my French speaking college students’ writing in Montreal. If you have insights into “Indglish” errors, please share. I will do my best to catch them with your guidance.

  5. I mostly use the grammarly addons for chrome to detect and fix grammar error but above shared tools are also great. I think you have missed a most powerful Grammar error detecting tool By SEO Tools Centre which can detect grammar errors up to 26 languages freely.

  6. Hi,
    Personally, I like Grammarly tool as an online grammar checker. I think this is only the best tool for professional writing. But most of the time I use my combine formula to write something in English. So that is a very interesting formula for me.
    However, thanks for sharing your list with us. Hopefully, this list will be more helpful for bloggers, students and freelance writer to write errorless writing.

  7. Hello Chamal

    A nice post, at the end. Writing a blog post take times, I love writing, though. However, when it comes to proofreading it, I always get bored and takes time. And thatโ€™s where tools like Grammarly or Ginger are used by me.

    Thanks. ๐Ÿ™‚

    • Hello Anuradha,
