10 Best Free Grammar Checkers | Tested & Reviewed

Are you tired of manually checking and removing all the grammar errors from your academic work? Whether you are a student or a writer, you need a robust grammar checking tool to ensure immaculate content. A piece of writing free of grammatical errors is necessary for effectively articulating your ideas, particularly in academic and professional writings.

Plenty of free grammar checkers are available on the internet, but how do you ensure which one deserves your attention? Here is where our piece can assist you. We have made a list of the most well-known ones in order of how many mistakes they can remove from the content. We have also considered the user friendliness of these tools.

Best Grammar Checkers Online

1. Quillbot

Quillbot is an exceptionally efficient tool when it comes to detecting and rectifying loopholes and inconsistencies in the content. It can easily recognise and remove all the errors found in any piece of writing. The Scribbr grammar checker, which is a subsidiary of Quillbot, is also a highly effective tool.

Moreover, both tools possess very user-friendly interfaces. The best part is the “Fix All Errors” button, which comes in handy when you have corrected numerous mistakes at a time. It saves the time and effort you need to put into manually clicking on each error.

Plus, you can easily start using them by just copying the text into the website without signing up first.

Upsides

  • Very quick to start using, as no sign-up is needed
  • You can download its extension for your browser
  • Offers an option “Fix All Errors” to conveniently fix various problems simultaneously
  • You can click on each mistake to separately remove it
  • Offers a shortcut to Quillbot’s paraphrasing tool
  • Multiple formatting buttons, including an “export” and an in-built “copy full text” button
  • It's completely free to use

2. LanguageTool Review

LanguageTool is also an excellent “best grammar checker free” tool. It can easily detect all spelling errors, punctuation errors and vocabulary mistakes. Like Quillbot grammar checker, this website is also intuitive to use, as no sign-up is needed. Also, the user interface is quite neat.

But you need to click twice to rectify a mistake, and you can't remove all errors simultaneously.

Upsides

  • Very convenient and swift to begin using the tool, as there is no need to sign up
  • You can use it throughout your browser with its extension
  • Offers several options when multiple interpretations are feasible

Downsides

  • There is no button to eliminate all inconsistencies at once
  • Requires two clicks to remove a mistake

3. SpinBot Review

Spinbot could recognise all loopholes in the content, such as punctuation, word choice and spelling errors. But it could not remove all of them. For some mistakes, it only pinpointed the wrong word but didn't give any corrected responses.

You don't need to sign up to use it, and it is 100% free. It is user-friendly because it highlights mistakes and enables users to click the button “Fix All Errors” to remove all mistakes at once.

But, contrary to some other grammar detectors, it doesn't explain why it shows a specific error in a certain word or sentence or doesn't let you dismiss rectifications exclusively.

Upsides

  • You don’t need to sign up
  • User-friendly interface
  • Allows you to fix all mistakes at once with a specific button

Downsides

  • Doesn't offer a description of mistakes
  • Doesn't have a way to dismiss corrections

4. GrammarCheck Review

This tool isn't as efficient as Quillbot and LanguageTool, but it worked well compared to other grammar checking tools. It can rectify approximately 6 mistakes out of 10 and doesn't add any new errors during checking.

Also, it is simple to use as you can start right away by just copying your content into the website. Plus, you only need to click once to revise the content suggested by the tool.

However, the website’s interface seems ancient. It also doesn’t allow you to eliminate all mistakes at once, like the other tools, with the help of a “Fix All Errors” button.

It has a “Deep Check” icon, which takes you to Grammarly, despite the fact that GrammarCheck’s own software does look a little different from Grammarly’s.

Upsides

  • You don't need to make an account to get started
  • Convenient and time-efficient, as you just need to copy the content in
  • You can accept a modification with just one tap

Downsides

  • The user interface is very primitive
  • There is no option to fix all mistakes simultaneously
  • The “Deep Check” option just takes you to Grammarly’s software

5. Grammarly Review

Grammarly works great than the usual grammar checking software however, it's not free. So, you can only see some mistakes it highlights after subscribing to a premium membership.

Grammarly’s free version can only rectify around 5 to 6 out of 10 mistakes, as we have already mentioned. Depending on the other elements of the content it underscores, it seems the premium version will only be able to find approximately 15 out of 20 mistakes. Which is still lower than Quilbot grammar checker, which is free too.

Upsides

  • The user interface is neat and decent
  • It offers several choices for alterations when multiple interpretations are feasible
  • Provides a browser extension
  • Offers several options when various interpretations are plausible

Downsides

  • A signup is required to start using which makes the process inconvenient
  • The process of rectifying mistakes is rather slow
  • You have to buy the premium version to view all the suggestions that it observes
  • Gives some useless suggestions
  • There is no option to fix all mistakes simultaneously
  • You need to click twice to remove a mistake
  • Doesn't show all suggestions at once, but rather only one type of suggestion at a time

6. Wordtune Review

Wordtune is a better tool compared to other grammar checking software, apart from LanguageTool and Quillbot, if you consider the mistakes it observes and rectifies. It can recognise approximately 6 to 7 mistakes out of 10.

However, keep in mind that Wordtune is a paraphrasing software, before a usual grammar checking one. You can't possibly exclude its paraphrasing feature from the fundamental grammar identification one, as far as we know. Therefore, it will rectify the majority of mistakes by redoing the work observed to have them.

It means it is not a go-to option if you wish to maintain your content’s structure.

We also observed that the paraphrased sentences can sometimes add new mistakes or substantially alter your meaning. And you have to make an account to get started, which makes the process inconvenient.

Upsides

  • Provides a browser extension
  • Can rectify 6 to 7 mistakes out of 10, which is higher than the majority of software

Downsides

  • Sometimes, recommended paraphrases have fresh mistakes
  • A few paraphrases substantially modify the context of your text
  • You cannot exclude individual issues
  • You have to redo complete sentences
  • There is no way to fix all errors at once
  • Rectifications need two taps
  • Sign-up is required for usage

7. Writer Review

Writer Reviw can amend errors, but it can also add fresh mistakes in the process. The issues it added were all punctuation mistakes. It looks as if the tool tries to make your sentence structure simple in an uncoordinated way by just eliminating parentheses and commas that are grammatically crucial. This leads to baffling and grammatically wrong sentences.

Moreover, its interface is super neat and user-friendly, and it enables you to make up each modification with one click. However, you need to create your account to use Writer Review. Plus, we won’t suggest Writer Review as it can add multiple mistakes.

Upsides

  • Provides a browser extension
  • Allows you to correct errors with a single click
  • Its interface is super neat and user-friendly

Downsides

  • You need to make an account to begin using the tool
  • Some fundamental modifications need a premium membership
  • You can't fix all mistakes with one feature
  • It puts wrong labels for types of mistakes, for example, spelling mistakes labelled as “punctuation”

8. ProWritingAid Review

Like Writer, ProWritingAid could recognise just a couple of loopholes or inconsistencies and add a few errors of its own. This tool adds issues because it recognises them but tries to remove them in the wrong way. For instance, it found that the acronym “C.O.P.D” isn't appropriate but recommended the solution “C.O.P. D” with a space added before the “D” — which is equally incorrect.

Furthermore, the interface is slightly intuitive to use. It seems attractive, but also crowded with useless data and choices shown haphazardly. Also, there is no need to create an account.

Upsides

  • Provides an extension
  • It has a super elegant user interface
  • Errors can be removed with just one tap
  • Offers various choices when several interpretations are plausible

Downsides

  • Account creation is needed to use it
  • Finding the tool on the website is difficult due to its slightly baffling design
  • It has a confusing and cramped interface
  • You can't fix errors with one button

9. Linguix Review

Linguix can fix approximately 1 out of 10 grammar issues. It notices some other errors that you can only unlock in the premium version. However, it sometimes couldn't recognise some jargon and just highlights them as a “spelling mistake” without providing any corrections.

Moreover, it's not convenient to use. Though it has a decent interface and allows one-click corrections, you need to create an account to modify content above a specific word limit. We would not even suggest using the premium version, as it also recognises less than 50% of the mistakes in the text.

Upsides

  • Nice interface
  • Allows correcting errors with one click

Downsides

  • You have to subscribe to the premium version to rectify most of the issues
  • Doesn't allow you to remove all mistakes with one button
  • Account creation is required to modify the content of a specific character limit

10. Scribens Review

Scribens can approximately correct 1 to 2 mistakes in content, but also add some new issues. It also provides various complementary functionalities that can be enabled if desired. Our team observed that those features can add different significant mistakes to the content if you enable them.

There is one feature that is supposed to find run-on sentences, but all it does is pinpoint all long sentences. These functionalities only work if you enable them, which is why they don't affect the quality of the tool's ability to help you fix your work. However, we advise not to use them.

Apart from that, Scribens has an intuitive user interface, but it looks outdated and works inefficiently overall.

Upsides

  • No account creation fuss

Downsides

  • Introduce fresh errors while removing the existing ones
  • Extra features usually develop text that makes no sense
  • Outdated interface
  • Fixing mistakes requires clicking twice
  • No way to remove all errors at once
