Linguix Grammar Checker


There are tens of hundreds of grammar checker tools on the internet, and unfortunately, not all of them are created equally.

Thankfully nearly all of the tools linked in this article are free, so you can get started using them instantly, but paid premium variants may give access to more features.

If you want to choose just one tool, then my vote will go to Grammarly, but keep in mind using the premium version gives access to a lot of additional features.

For a completely free option, Hemingway is a solid pick, but unlike Grammarly, it doesn’t have a browser extension available.

The best way to combine the two is to use the free version of the Grammarly extension and later copy/paste the text into the Hemingway app to rectify any additional errors. This method gets you the best of both worlds while being completely free as well.

Although these tools can certainly help you with rectifying your errors, it should be kept in mind that none of these tools are 100% accurate, and you will need to have a good grasp of the English language to correct errors even if the computer can’t detect.

Another thing to keep in mind is that random free grammar checker tools on the internet may steal your content. Therefore it is better to go with the trusted names only.
