Writing for the web is quite challenging, especially for non-native English speakers like me. Wrong use of words, missing punctuations, conciseness, passive voice, etc… are some of the reasons using online grammar checkers for free is a necessity. 

And if you’re a beginner on a tight budget, you don’t have access to request the service of a professional proofreader, which makes things even worse.

The best option is to use a free grammar and punctuation checker and corrector tool. So your content can read better, with fewer errors, typos, and increased readability.

There are lots of free grammar checkers and punctuation online tools available today. I have listed some of the best free alternatives to paid tools. You can go through the list to find the one that best suits your needs.

Some tools have free and paid plans; you can compare the free features to a paid plan to see what features are missing if you remain in the free plan.

However, being on the free plan might be enough for many writers and businesses. With that in mind, let’s explore the list below.

8 Best Free Online Grammar Checker Software

#1. Grammarly


Grammarly is unarguable, the most popular online text editor and grammar checker tool in the market. 

It is an AI-powered writing assistant tool that lets you check your document for grammar, punctuations, word choice, passive, synonyms, typos, wordy sentences, conciseness, etc. Also, you can check your content for plagiarism, correctness, clarity, tone, complex sentence, word choice, and more.

The Grammarly text editor lets you write in a clean distraction-free interface so you can focus on making your content better. 

You can integrate Grammarly with your favorite browsers through an extension and start checking all your online writing.

So it is possible to use Grammarly on your WordPress text editor, social media, email, in-app, etc. Anywhere you write online, you can use Grammarly.

Microsoft Editor

Microsoft editor is a simple add-on extension that works with most chromium browsers – Google Chrome, Edge, Safari, etc. So you can use it anywhere you write online.

It’s available as part of the Microsoft 365 suite, but you can download and use it for free.  Microsoft editor checks for spelling mistakes, grammar, and refinements.

When writing, it highlights the text correctness in different categories; the red-dotted underlying checks for spelling mistakes and the blue-dotted underlying feature checks for grammar and text refinements.

Unlike Grammarly, Microsoft editor is not a feature-rich text corrector tool, but it’s enough for online writing. Though the extension is available as a free browser add-on, you need to buy Microsoft 365 suite to gain access to sentence refinements and support for over 20 languages.

The entire Microsoft 365 suite costs $69.99 for a single plan and $99.99 for the annual family plan.
