Proofreading software 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?
It isn’t, of course, because most of us take pride in our work. Editing and proofreading takes up a serious amount of time for any writer or blogger (even more for those starting out).
This is where proofreading software can come in. It automatically identifies different types of errors in real-time 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 tell you which is the best proofreading software and why.
No angle, no bias, and no bs. Just good, honest insight.
TL;DR I’ve always liked using Grammarly. Now I know it’s the best after reviewing the competition! It has the smartest AI, the cleanest interface, and the premium version is the best value proofreading software on the market. Try it for free

3. Ginger Software
According to them, Ginger is described as:
“The Ginger Grammar Checker 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.”
Ginger is compatible with the major word processing packages (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 application currently (only the Safari browser extension and iOS app are available currently), and does not have any kind of plagiarism detector.

- Unlimited real-time proofreading
- Correct a vast range of writing errors
- Rephrase sentences to improve clarity and style
- Context optimized alternative writing suggestions
- Over 60 language translations available
- Practice on your mistakes with personalized practice sessions
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.
Whitesmoke claims to detect hundreds of previously undetected spelling errors, as well as provide corrections for grammar, 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.

Verdict: another older proofreading software application that hasn’t kept up on look, feel and interface. It’s 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 best proofreading software.

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 groundbreaking). 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.

Which is the Best Proofreading Software?
The winner is Grammarly.
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 super-clean, totally intuitive and 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 is the best proofreading software for writers wanting 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.
For marketing copy, the best proofreading software is Writer.
This doesn’t win the title of ‘best proofreading software’ but that’s because it’s not trying to. Writer is one of a kind because it’s the only proofreader that helps ensure your content contains consistent brand messaging.
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.
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.
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. 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!
Make sure it is suitable before subscribing to ensure your future writing endeavours get the most out of it.
How does Artificial Intelligence work in proofreading software?
Artificial Intelligence (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 does the checking and suggesting, 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 a spelling mistake (to be honest, Microsoft Word never did if I recall!) but advanced grammar and style are 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 and why.
Which brings me neatly onto the style of writing which is both personal and subjective. Sometimes you might purposely frame a sentence or misuse a word for effect, for example, or simply find a style that suits you regardless of ‘the rules’.
The best proofreading will always be done by a human editor who wouldn’t miss the subtleties of different types of writing scenarios.
To be honest, I use Grammarly purely for the real-time ease of getting spelling, grammar and basic style corrections sorted in real-time as I write.
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.
