Best of The Best: 10 Online Grammar and Punctuation Checker Tools 2020


If you are planning to start a blog or your new job includes blogging duties, you will need to work on improving your writing skills. You can never perfect your writing. It should be a constant process of self-improvement.

One of the most important aspects of writing is your grammar. Nobody will take you seriously at this job unless your content is perfect. Luckily there are a lot of online grammar and punctuation tools that can help you with improving your writing quality.

I know what you are thinking – I should be able to fix my mistakes and proofread my writing. But, the fact is that even famous writers have editors and proofreaders who double-check their content. It is a regular thing when you do a lot of writing because you are not a machine that doesn’t make mistakes.

Given the fact that you are not a famous writer and don’t want to spend a fortune on editors, the best option is to find a reliable writing tool. That tool should help you to filter your writing and improve all the tiny mistakes that mean a lot.

How to choose a grammar checker software

No two grammar checker software solutions are made equal. Each one has its specific features and integrations. Before you can choose one, you have to compare it against your personal needs and preferences. Here are a few things that you should know if you want to be able to choose the right grammar checker software for you.


When it comes to price, you have several options. There are a few grammar checker tools that offer free unlimited use but with limited access to features. If you are a native English speaker this might be a great way to save some money and still benefit from the software able to fix small grammar mistakes.

Grammar checker software companies have different pricing policies. This is why you will be able to find solutions available as one-time purchases, monthly, quarterly, yearly, and three-years subscription plans. The monthly subscription plan is very convenient if you don’t have a constant workflow. You can decide when you want to use the tool and cancel the subscription afterward.

Finally, the grammar checker software market is flooded, and you can often see these tools on attention-grabbing discounts. If you are not in a desperate need of one, we suggest you identify the one that suits you best and wait until its price drops.


All grammar checker solutions can be divided into two categories – on-premises and cloud-based solutions, or in layman terms, tools that work offline and online. Since only you know when and where you prefer to write, you will have to decide. Offline grammar checkers are convenient when you are on a constant move and don’t have access to the internet.

Online tools come with considerably more features and support more integrations. We will come to this later on. There are even some tools that work perfectly fine when you are either off and online. The bottom line is – if you find a tool that suits your personal needs, in terms of integrations and features, make sure to check whether it exclusively works online, offline or supports both modes.

Furthermore, grammar checkers offer dedicated standalone apps for major desktop and mobile operating systems (Windows, Mac OS, Android, and iOS). Make sure that your favorite OS and device are supported before you buy it.


Grammar checkers are not only designed to help you improve your proficiency in English, but also make sure that your content is unique. Each one of the tools comes with a specific set of features. Some of these features are only accessible in specific subscription plans.

Make sure to double-check the feature list accessible for the plan you want to purchase before you settle with the final decision. You don’t want to end up paying for a plan that comes with features you are likely never going to use. All features can be placed in 5 big categories – spelling, grammar, punctuation, writing style, and plagiarism checker. But these are the core features that every grammar checker will have to offer, more or less. There are also additional, more attractive features that this software can come with.

This includes a personal dictionary, online editor, writing statistics, grammar rules, vocabulary, and so on. Only pursue the features that you think you can benefit from in terms of streamlining your workflow.

Ease of Use

Are you a tech-savvy writer? Then you might be interested in grammar checkers with advanced interface options and app settings. On the other hand, if you don’t have the time to go through all those neat tune-ups and want an app that seamlessly integrates into your workflow, there are lots of options for you as well.

Remember, ease of use also applies to the installation process. We suggest that you try out the tool you are interested in to get the feel about its complexity. Hit the YouTube videos and asses the app’s ease of use. Tutorial and showcase videos can be really useful for this.

Since it is still a piece of software that we are talking about, you may experience trouble using it, or it may start behaving oddly and even stop working completely. This is why you should make sure that the company in question offers customer support.


Integration is a powerful grammar checker tool feature, especially if you enjoy working in a cloud environment, such as Google Docs. As we have mentioned earlier, some grammar checkers have dedicated desktop and mobile apps. This enables them to check your grammar and spelling in apps whenever you use your keyboard to type.

If your favorite tool is one of the popular office packages such as Microsoft Office, LibreOffice, WPS Office, Apache OpenOffice, or any other for that matter, you have to check if the checker supports integration with your favorite tool.

There are also browser integrations. Grammar checkers offer plugins for popular browsers including Google Chrome, Safari, Mozilla Firefox, and Opera. It’s worth checking this out if you spend a lot of your time corresponding with your clients online, responding to comments on your online blog, and so on.

  1. Writing in English is difficult for everybody who is not strong in the English language. Sometimes you might think that you have written a perfect post but did you know that small mistakes can give away to the charm of your writings. So, it is wiser to use Noun Plus grammar checker tool.

  2. I use Grammarly and I particularly love the features. It works both on my phone and pc and it has significantly improved my writing skills. I totally recommend them to everyone who really wants to get serious with professional writing.

  3. Wow. This list has everything and I’m not even sure which to pick anymore. They all have amazing features and I’m sure they will work just as I want. Maybe I’ll try the Grammarly since I heard a lot of good reviews about it.

  4. Grammarly is the best. I have it as an extension in Chrome and also in my MS Word application. It has made writing a lot easier and the fact that I get reasons and explanations on each error is enough to improve my vocabulary and writing.

  5. I’ve used like 4 of the tools on this list and they all delivering the expected results. If you write professionally, or even for yourself, you may want to have one of these to make the whole thing a lot easier and faster for you.

  6. I have no problem with grammar, being a college English teacher. But I am an abominable speller. So I need a spellchecker that is 50 times better than the ridiculous one that comes with WORD, which is beyond belief stupid and idiotic! I also don’t know how to download a superb spellchecker that will automatically open in Word every single time without me having to do anything special. I’ve tried following online directions, but I just don’t understand them, and they don’t function for me.
    Suggestions for a smart editor that is dim about spelling and computers??

  7. For years I have been stalling trying to write a book but didn’t have a clue of how to put together the manuscript because I had major problems with grammar, spelling, and simply putting a manuscript to begin with!

  8. Thank you Anja for this great list of grammar checker tools! I’m using Ginger Online and for a single payment of $40, you can get it for life.

  9. For all the mistakes, Grammarly will give you an explanation of what you did wrong and offer to improve or replace errors. Great tool for a small price!
