Which Free Proofreading Software Is The Best?

The best free proofreading software online features a scanner that catches at least 90% of grammatical errors, corrects errors accurately, and gives a readability analysis. It also scans and corrects grammar accurately, and there are no limits on its functionality as a grammar checking tool. I have dealt with a lot of proofreading software in my profession. Not all of it measures up to my demanding standards. So, what free online proofreading software is the best? And which free proofreading programs are worth downloading? Let’s see!


Ginger is one of my favorite free proofreading programs. It has a remarkable ability to train the user to use better grammar. The scanner is top notch and catches most errors. Ginger itself can be used with a wide variety of programs thanks to its handy popup window. It only is guaranteed to integrate with Microsoft Office, though. It can be a sore point for those who prefer a more all-in-one solution.

Ginger comes with both a free version and premium version. The free version limits the number of texts you can check but otherwise is fully functional. The premium version costs as little as $7 a month if you purchase a year’s subscription. It goes up to $20 a month if you are buying it on a monthly subscription basis. There is a discounted subscription plan available for students.

I have used Ginger for general proofreading in documents and forms.


LanguageTool is a free proofreading app that is available as a browser plugin and as a Google Docs add-on. It is most notable for its excellent integration into these environments. There also is an explanation of the edits it suggests. LanguageTool uses the internet to help it make decisions about grammar, so sometimes its checking can be a little off. However, it has an extensive vocabulary due to its AI programming.

I have made the most use of LanguageTool in my browser. It’s fantastic for on-the-fly proofreading with online forms and text boxes.


GradeProof is a website that also has a Google Docs plugin. It features a highly sophisticated scanner that catches grammatical errors and improves upon the elegance of language you’re using. GradeProof is best known for its excellent coverage in scanning, customizability in how it scans, its plagiarism checker, and thorough readability analysis reports.

The free version is not all that great due to its limitations in scanning (no elegance checking), lack of plagiarism checking, and restriction on the number of scans. Also, GradeProof is only good for uploading documents and Google Docs. Other than the Google Docs add-on, there is no integration. However, even the free scanner can be useful for its readability reports and double checking prior proofreading.

GradeProof is $15 a month for a subscription, and outside of Ginger’s year-long subscription service, is the cheapest proofreading software I’ve found.


WriteClearly is a proofreader on a mission to improve the readability of documents and websites everywhere. Like GradeProof, it is only available as a website and a Google Docs plug-in. However, it does feature a handy bookmarklet to help you get to the scanner quicker. WriteClearly doesn’t automatically fix errors. It does give suggestions on how to improve your writing and a Flesch-Kincaid scale readability score.

WriteClearly is an excellent companion to LangaugeTool if you’re only sticking to free proofreading software. It helps fill in the gaps LanguageTool leaves behind in its scanning, and it gives a readability score.

Who’s the Winner?

It’s a close call between Ginger and GradeProof and depends much on your needs. If you need a great all over proofreading app and don’t need readability analysis, Ginger is probably going to make you happiest. If you mostly need proofreading software for documents and websites and need a readability analysis, GradeProof is your winner.

LanguageTool also deserves an honorable mention for doing such a fantastic job at scanning and correcting grammatical errors for a free proofreading software tool.

Of course, the best proofreading is always going to be human. Even with these tools in place, it takes a human to go through the suggestions and make a wise call on whether or not to implement them. For critical jobs, your best bet is to get a human proofreader to go over your work.
