Final Words

As humans, we have 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, an article will cost you a few hundred dollars. 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!

So, what’s your best grammar and punctuation checker tool?

  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 didn’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 that’s where tools like Grammarly or Ginger are used by me.
    This is an AWESOME post.
    Thanks. 🙂

    • Hello Anuradha,

      Yes, of course I too face your problem. When it comes to proofreading, I too little bit step back. Because it’s boring. However, proofreading is a great way to find errors and missings on article. My best grammar tool for proofreading is Grammarly.

      Thanks for your awesome comment!
