9 Best Proofreading Software For Better Writing in 2022

Proofreading software (a.k.a. a ‘grammar checker’) has become much more in demand and finding the best one, even more so.

We’ve been living in the digital age since the first personal computer appeared in the 1970s. Five decades later and it’s no surprise most written information exists on screens because it is continually exchanged between people using computers. 

Imagine if it was full of grammatical errors and spelling mistakes?

This is where proofreading software comes in. It automatically identifies different types of errors as you type and simultaneously offers guidance to improve your writing style.

Of course, some of these editing tools do it much better than others. There is the good, the bad and the ugly. I’m going to help you find the best proofreading software for your needs by illuminating their key differences.

No angle, no bias, and no bs. Just good, honest insight. 

TL;DR I’ve always liked using Grammarly but now know it is actually the best out there. It has the smartest AI, the cleanest interface, and the premium version is the best value grammar checker on the market. Try it for free

Proofreading Software Recommendations

Grammarly – Best Overall Proofreading App

I wholeheartedly recommend Grammarly if writing (on a screen) is important to you. Currently, it’s the standard by which all other proofreading tools are judged by.

In my experience, nothing else matches Grammarly’s AI. Couple this with its state-of-the-art design & user interface and the overall user experience is unmatched.

It’s a super-clean and totally intuitive grammar checker that is completely unnoticeable when not in use. As a result, you quickly come to trust Grammarly’s capabilities which means improved writing and value for money almost immediately.

What else do you want from proofreading software?


ProWritingAid – Best for Writers Who Want to Learn

This is one of the better proofreading tools I reviewed coming in a close second to Grammarly (with Writer discounted as explained). What sets this software apart is the in-depth reporting which is the most comprehensive out of all the options. 

The reporting is a bit much for my needs and thus unnecessary. However, it would be perfect for anyone who really wants to improve their writing skills.

The free version is online proofreading only but still an easy way to try it out.


Writer – Best for Marketing Copy & Agencies

Simply put, Writer is one of a kind because it’s the only ‘grammar check’ software that ensures your content is a ‘house style’ and stays on-brand. It is more business-grade marketing software, than grammar checker.

This proofreading software was new to me but what a find! It’s a different proposition designed for producing ‘on-brand’ copy more easily. Writer lets you set various parameters around your brand which it then ensures are present in your writing.

It’s AI is uniquely powerful compared to any other proofreading app out there and impressive. Definitely worth a try if you need to inject some brand character into your writing.

4. Ginger Software

proofreading software free

According to them, Ginger Software is described as:

The Ginger grammar check helps you write better English and correct texts more efficiently. Through the use of patent-pending technology, Ginger Grammar Checker analyzes the context of your sentence to correct grammar mistakes, misused words and spelling mistakes with unmatched accuracy.

proofreading programs

Ginger is compatible with major processor packages like Microsoft Word (although not Google Docs). It also works across the main social media platforms. Extensions can easily be added to Chrome and Safari, or there is a Windows desktop app if you prefer. 

Note – Ginger is not compatible with macOS as a desktop app currently (only the Safari browser extension and iOS mobile app are available currently), and does not have any kind of plagiarism detector.

‘Free’ Features:

  • Definitions

  • Context optimized alternative writing suggestions
  • Over 60 language translations available
  • Practice on your mistakes with personalized practice sessions
  • Mobile app for checking on the go (Android & iOS)

Verdict: an older tool that looks modern on the face of it but has now been left behind by smarter AI in other proofreading software. Editing is okay but lacks fluency compared to the competition. Not great value for the price.


5. WhiteSmoke

proofreader app

Whitesmoke claims to detect hundreds of previously undetected spelling errors, as well as provide corrections for its grammar check, word choice, and also style mistakes. Its products are based on Natural Language Processing (NLP) technology, featuring unique and patented Artificial Intelligence (AI) and algorithms for text analysis.

proofread software

The tool can be online-only or a full desktop app that integrates with Windows or macOS, or as a mobile app for iOS and Android.

‘Web’ Features: 

  • Online-only application
  • Spelling and grammar check
  • Plagiarism detector
  • Translator

‘Premium’ & ‘Business’ Features:

  • All standard features
  • Fully integrated desktop application (or browser extension)
  • One-click instant proofreading
  • Integrates with all writing platforms
  • Up to 3 licences
  • Phone custom support (Business plan)
  • Extended download warranty (Business plan)


  • Writing templates (cover letter, proposals, thank you letters)
  • Detailed error explanations
  • Comprehensive library of video tutorials
  • Over 55 language translations available

Verdict: another older grammar check application that hasn’t kept up on look, feel and interface. Its AI is decent enough but the whole thing just feels a little out of date: from the website to the speed of correction. Then, there’s the cheap price which is fitting but still doesn’t make it a contender for the best proofreading software. 


6. LanguageTool

proofreader software

LanguageTool is compatible with Chrome & Firefox as a browser extension, or as an add-on for Microsoft Word, Google Docs, and LibreOffice. There is a full desktop version on Windows or macOS for offline use.

  • Cheapest grammar check out there
  • Easy to use
  • Developer API optional
  • Over 27 language translations available

Verdict: cheap and cheerful web-based proofreading tool with an offline version. No deeper technical reporting or plagiarism detection. Typical of open source software: simple and fast but comparatively lean in functionality. Brilliant forum, decent free version and a cheap premium plan if sophisticated writing guidance is not needed.


7. Outwrite

book editing software

Outwrite is available online through any browser with a live internet connection. They also offer a browser extension for Chrome, Microsoft Word, and Google Docs, and a mobile app for iOS.

writing editor software

  • Experimental suggestions
  • Priority email support


  • Solid grammar and spelling checker
  • Ensures vocab variety
  • Stylistic and structural improvements
  • Strong paraphrasing tool
  • High discounts on annual subscriptions

Verdict: very easy on the eye with branded functionality on their premium version like the ‘eloquence engine’ that checks the use of the passive voice (hardly ground breaking). Their unique selling point is that it’s online-only; the biggest weakness is being online only! It might appeal to some but this proofreading software lacks substance against the competition. Poor free version too.


8. Paper Rater

free proofreading software

According to PaperRater:

You want instant gratification and so do we. Using Artificial Intelligence and Data Science, submissions are analyzed in real-time with results typically appearing 5-15 seconds after submission. Our cloud-based software digs deep into the syntax and structure of your text without the need to sign up, login, or download.

  • Brilliant tool for students
  • Free version is powerful enough for most
  • Suggestions indexed against other students
  • Readability analysis is very useful

Verdict: Online proofreading software aimed at high school assignments and college essays. Has some interesting and powerful features including ‘essay scoring’ and plagiarism detection but a horrible user experience. Quirky and useful for young adults but no one else (free version or paid).


9. Hemingway App

Bad grammar mistakes and spelling errors will negatively affect the credence of your writing no matter what. There’s no question you need to proofread your work, especially if it’s a professional article, document or report.

It makes sense to find the best proofreading tools for your writing. In fact, everyone should use writing software to automate what can be a time-consuming task.

The recommendations in this review are based on my experience and needs which, whilst common, are specific to me. Grammarly offers the best package around both in its free and premium versions.

Your requirements might be different and be better served by one of the other editing tools. Whatever you do always try before you buy.

Each of these applications has a free option in some form. Use it to find the best grammar and spelling checker for you.

Make sure it is suitable before subscribing to ensure your future writing endeavours get the most out of it.



How does Artificial Intelligence (AI) work in the proofreading software?

AI is a term used to describe machines (typically computers) when they mimic learning and problem-solving functions. Machine learning is applied AI when systems are able to automatically learn and improve without human interference. 

The best proofreading software utilises both of these technologies. The software’s AI is the grammar checker, whilst the machine learning records and processes lots of varying inputted data (including that of a user) in order to learn new outputs. 

What are the limitations of the best proofreading software?

Whilst the AI in some of these apps is truly impressive there is still room for improvement.

I’ve never known Grammarly to miss spelling errors but advanced grammar checking and writing style guidance is another matter.

This is because these types of errors are often contextual; each word in the sentence is fundamentally correct but as a whole, it doesn’t work. What’s more, even if it does manage to flag such an issue there is little in the way of an explanation of how to fix it and why. 

This brings me neatly onto writing style which is both personal and subjective. Sometimes you might purposely frame a sentence abnormally for effect or simply use a style that suits you regardless of ‘the rules’.

Proofreading by a human editor who won’t miss the subtleties of different types of writing scenarios will always be the best option.

To be honest, I use Grammarly purely for the ease of getting grammar checking and spelling plus basic style corrections sorted in real-time as I write. It works with Google Docs, MS Word and iWork as well as on any web browser and as a brilliant mobile app.

After that, if my work needs proper proofreading, I’ll print it out and go through it the old fashioned way: with a pen and paper.
