Hemingway is another well-known online spell checker tool. This grammar checker tool is web-based though, so you can’t use it within WordPress or any other app. So, unfortunately, if you want to start a blog, you can’t proofread and edit your posts from your WordPress dashboard with this spell checker tool.

To use Hemingway, simply copy and paste your text into their app and the tool will check your writing for spelling and grammar errors.

The tool’s distraction-free interface allows you to quickly find errors, so you can publish your polished content as fast as possible.


Hemingway not only checks your writing for spelling and grammar errors but it’s also a style checker too. This tool uses an eye-catching, color-coded system to point out wordy sentences, complex words, passive voice, and adverbs.

For instance, Hemingway suggests you remove adverbs to make your writing stronger and will highlight adverbs in blue.


Hemingway will also help you improve the readability of your writing by giving you a readability score and provide suggestions for improvement.

It’s important for your content to be easy to read, otherwise, no one will want to read it. So, this grammar checking tool is great for helping you write content for your blog or website that’s easily understandable for your readers.


You can use the web-based Hemingway app to check your writing for errors for free — it won’t cost you anything to use the online grammar checker software.

But, you can also purchase a desktop version for Windows and Mac for only $19.99.


Purchasing the desktop version of Hemingway will allow you to post directly to WordPress, use the tool without an internet connection, and import and export easily from other programs like Microsoft Word.

Jetpack is one of the most popular WordPress plugins of all time. It’s an all-in-one plugin for design, marketing, and security. But did you know that it’s also one of the best grammar checker software too?

Jetpack calls their grammar checker software After the Deadline and it’s available right inside the Jetpack plugin.

Simply download the free Jetpack plugin. Once it’s installed and activated, head to Settings. In the Writing section, turn on the Check spelling, style, and grammar button. Once you turn it on, you can also choose additional options for what you want the tool to check for.


After you’ve turned on the spell checker setting and set your preferences, you’ll then see a check mark button added to the WordPress editor toolbar. Simply click the button to check for spelling and grammar errors in the blog post or page.


You can then click on each color-coded, underlined error the tool finds to see suggestions to fix the spelling or grammar mistake.


The only downside to Jetpack’s grammar checker software is that it doesn’t currently work with the new Gutenberg WordPress editor. With the Gutenberg editor, there’s no spelling check mark symbol on your screen anymore like in the classic editor and the Jetpack plugin doesn’t pick up errors as you’re typing.

So, if you want to use Jetpack to find errors in your blog posts and WordPress website, you’ll have to disable Gutenberg and go back to the classic editor in WordPress.

For step by step instructions for how to do that, check out this guide on how to disable Gutenberg and keep the classic editor in WordPress.

Jetpack’s grammar checker software is pretty basic in its feature set, mainly because the grammar checker software is not the main focus of this plugin.

But even though the feature set is basic, the plugin still has a number of features that will make checking your blog posts for errors easier, including:

  • Color-coding to easily recognize spelling, misused words, grammar, and style errors.
  • Option to run the proofreader automatically before publishing or updating a post.
  • The ability to ignore errors 1 time or always.
  • Available in English, French, German, Portuguese, and Spanish.
  • Advanced grammar checking options such as biased language, cliches, double negatives, passive voice, phrases to avoid, and more.


Jetpack is a free WordPress plugin. So, you can use it to check your grammar and spelling for no cost to you at all.

They do, however, offer a number of paid plans that give you access to a number of advanced features. These plans start at $3.95 per month.

Upgrading to a paid plan with Jetpack will not get you advanced grammar checking features though. The paid plans are for increasing performance, security, traffic and revenue, site activity, and support features.
