The Best Grammar Editing Software

This article is all about the best grammar editing software, but did you know that EditorNinja provides grammar editing services? We’d love to edit your content for you. Click here to schedule a free editorial assessment to learn more.

As a content creator or company creating content, you know that your copy should not only be persuasive and achieve your goals but it should also be grammatically correct and free of typos.

Even the best writers make mistakes, after all. According to editors commenting on this StackExchange thread, 1 typo per 1,000 words is simply too many and most of them aim for about 3 per 10,000 words (or on average 1 per every 3,333 words).

Professional editors of course are extremely valuable and are a necessary part of any content team or company. EditorNinja wouldn’t exist if they weren’t!

But technology has also enabled computers to do some of the more tedious work that editors have always done. Technology is a beautiful thing, and so we too embrace it here at EditorNinja to help our editors do an even better job than they’d do on their own. While we embrace it, we also know that human editors can make judgment calls and spot errors that even the best technology cannot.

Grammar checking apps have become very popular over the last few years, and since we use them ourselves we figured we’d round up the best grammar checkers available so you too can check them out and use them to make your writing better before even hiring an editor or working with EditorNinja for that final pass over your content before it’s published.

Here are the top 7 grammar editing apps available for you to check out and use to ultimately improve your copy. As you will see, almost all contain both free and paid plans as well as a Chrome extension you can use to check your writing as you write in your browser.

These listed grammar editors are all self-serve tools that you can leverage to write better copy and do some basic edits yourself. If you want to save time with an affordable editing service that lets you focus on strategy and creation, EditorNinja is here for you. Start here today.

Hemingway App is a writing tool and editor that edits as you write. With both a web-based and desktop app, Hemingway is a a good option for writers who like to have edits suggested to them as they write.
