Content writing can sometimes be challenging, especially if your website or your client’s website requires you to alternate between the US and UK English.

Fortunately, there is a range of free online proofreading tools that can make this process much easier, helping you avoid any grammatical errors or spelling mistakes.

In this article, we will run the rule over 6 of the best free online proofreading tools of 2022, providing you with the pros and cons, and finally revealing which we think is the best overall.

What Is a Proofreading Tool, and Why Would You Need One?

A proofreading tool will check for spelling and grammatical errors, highlighting any issues so they can be quickly edited.

This can ensure any articles or copies you write are free of mistakes while also teaching you to check for these errors in the future, ultimately making you a better, more careful writer.

Even if you are an experienced writer, we still recommend having at least one proofreading tool installed to cast a second pair of eyes on your work.


Proofreading tools can assist with a range of requirements, including creating blog posts on platforms such as WordPress.

🔵 What Types of Content May Need Proofreading?

Pretty much any form of content that will be published online requires proofreading to ensure everything is spelled correctly and reads well.

Content may include:

  • Blog/ Article Posts
  • Copy for Web Pages
  • Social Media Posts
  • Research Papers
  • Informative Studies
  • Infographics
  • PDF Brochures
  • eBooks

Let’s now move to the list!

We have compiled a list of our 6 favorite online tools for proofreading that are available for free. Some of our picks may have premium versions that offer additional features, however, each tool can complete the job without the need to invest in the premium package.

1. Grammarly


Number 1 in our list is Grammarly, helping anyone from children to professional writers improve their content.

The free version is more than enough for most writers, while the premium option offers a great range of benefits for regular users.

Grammarly provides all the features you would expect, including checking for spelling, grammar, sentence structure, and plagiarism.

Checks are made in real-time, and the content is given an overall writing score to assess its quality.

Grammarly has established itself as the leading proofreading tool and offers three premium plans – a monthly plan ($30/ month), quarterly ($20/ month), and annual ($12/ month). Business plan starts at $15/month for per member.


The premium option provides double the number of corrections and suggestions to create very high-level articles, while plagiarism checking is also much more advanced.

Grammarly is also available as a web browser extension that automatically highlights any errors you make while typing.

This means Grammarly can be active at all times, whether you are editing a WordPress post, or creating a Google Doc.

Grammarly browser extension can sometimes slow down your browser (for example, when you are editing a long form article on WordPress). So, if you notice slow browser speed, try temporarily disabling Grammarly.


  • Market-leading spelling and grammar checker
  • Real-time suggestions
  • Useful article reporting features
  • Provides a simple list of suggestions, so you don’t have to read through the entire document


  • Advanced writing suggestions are only provided in the premium version

2. Typely


Making the top two of our list is Typely, which is a great fit for writers of all levels and disciplines.

This tool has a wide range of features that can be customized based on your requirements.

Typely also provides cool reports that show your overall rating as a writer based on its findings.

Typely is free to use, and as a relatively new tool, development is ongoing, so it is updated and improved regularly to provide a better experience and more accurate checking.

Although it is browser-based, checked content can be downloaded to Google Docs to be saved permanently.


  • 100% free
  • Feature-heavy
  • Regular Updates
  • Great reporting


  • Lacks a plagiarism checker
  • Documents cannot be uploaded
  • The amount of characters that can be checked is capped at 50,000

3. Slick Write


A very capable proofreading tool that checks the content and copies in real-time, while also providing formatting suggestions. This tool is completely free, but donations (tips) can be given to the developer if you wish.

One of the major benefits of this tool is that you can define the subject of the content before checks are made, creating a more bespoke experience for each article.

Checks will also be saved so you can take a break and come back to the content later.


  • Checks can be customized for specific subject matters
  • Completely free
  • Great functionality
  • Google Chrome and Mozilla Firefox extensions are available


  • Some ‌suggestions provided are a little ambivalent and you may ignore some recommendations.

4. Paper Rater


Paper Rater is a great option for more basic writing, mainly for high school students and perhaps for people who are just starting their writing journey. Despite this, it doesn’t stop it from being a handy tool that has great functionality.

With the free version, users can only check a maximum of 5 pages in a single submission, with 50 submissions a month and 10 plagiarism checks per month. The checks include grammar, spelling, writing suggestions, and an overall scoring of the submission.

The premium version costs $7.95 a month, although there is a 25% discount available occasionally.


The premium version is without ads, files can be uploaded, enhanced plagiarism checking is available, and checking is processed faster.


  • Fantastic proofreading capability
  • Good plagiarism checking in the premium version


  • The free version is more limited compared to the premium equivalent
  • Not a great for professional or business writers

5. ProWritingAid


This free tool is perfect for a range of content creators, from bloggers to non-fiction authors, and even students just checking their latest essays. It is extremely responsive, with a slick user interface, making it very easy to use, and unobtrusive while you are writing.

The free version provides a summary report of all the key issues, with over 20 writing reports available. One drawback is that this version can only edit 500 words at a time and can only be used online, meaning it might not be perfect for everyone.

Besides the free version, there are also two premium versions.

  • The $79 a year version has no word limit and can be downloaded to your desktop to be used offline, with integration with Google Docs, MS Word, Chrome, and more.
  • The $89 a year package offers 60 plagiarism checks a year, which makes it perfect for students.

We think this is a powerful proofreading tool, but the free version has some restrictions that may put some people off.

Let’s look at the pros and cons.


  • Great for identifying issues relating to sentence construction
  • Powerful grammar and spelling checker
  • Real-time suggestions to improve readability
  • Creates summary reports to rate the content overall


  • They limit the free version to just 500 words
  • Plagiarism checks are only available in the highest pricing band

6. Writer – Proofreading Tool


Proofreading Tool is predominantly aimed at people writing essays or business (B2B) content.

It checks for many issues, including colloquialisms, poor use of verbs and punctuations, as well as highlighting sentences and phrases that are difficult to read.

This tool is quick and responsive, meaning there is little to no lag when writing, so errors are flagged almost instantaneously. This option isn’t a great fit for creative writers or anyone writing in an informal tone, but if your writing needs to be serious and accurate, the Proofreading Tool is highly recommended.

Writer is a free tool that has a pro version which costs $11/ a month. With this version, you will have access to a range of more advanced suggestion features. Meanwhile, the team version costs $18/ per user, per month and offers fantastic collaboration features.


  • Provides excellent sentence suggestions
  • In-depth grading and reporting
  • The progress of the proofreading can be saved for later
  • You can paste or upload large chunks of text to be checked


  • It requires registration to use
  • Not great for creative or informal writers
