Why Add a Grammar Checker Tool for WordPress?

Even the most experienced writers make mistakes. Proofreading your own articles often leads to making small, careless errors because we tend to rush through the pre-publish checklist.

Typos and grammar mistakes in your blog posts can make your content look unprofessional. They can also make your articles hard to understand, which is bad for the user experience.

One way to overcome this issue is to read your articles out loud. Listening to your voice can help you find mistakes and improve the overall readability score of your blog posts.

To help you with grammar and spelling, you can also use a grammar checker tool. These tools can detect spelling and grammar mistakes as you type. This saves you time on proofreading while improving content across your WordPress site.

How We Test And Review Grammar Checker Tools

To give you the best recommendations, we tested some popular grammar checker tools on real websites. When doing that, we focused on the following criteria:

Ease of use: We have prioritized tools that are beginner-friendly and have an intuitive interface that makes it easy to correct grammar and spelling.

Accuracy: We evaluate the tool’s ability to detect and correct grammar and spelling errors by testing it with a variety of text samples.

Reliability: For this showcase, we have only added the tools we have tested ourselves in real time.

That being said, let’s take a look at the best grammar checker tools that you can use on your WordPress website.

1. QuillBot

QuillBot is an amazing AI writing assistant that offers a grammar checker for English, French, Spanish, and German. It also comes with a free extension for Google and Microsoft Word.

Besides that, the tool also has a built-in plagiarism checker that ensures your work is original and can scan up to 20 pages per month.

We really appreciate QuillBot’s summarizer that can condense your content into bullet points or a shorter paragraph. You can also adjust the length of the summary according to your liking by using the slider at the top of the tool.

Pros

• QuillBot has a paraphrasing tool with multiple accuracy modes and a synonym slider. It can paraphrase your content in up to 23 languages.
• It has a citation generator and a language translator.
• The tool also gives insights into your content tone and lets you view your paraphrasing history.

Cons

• We didn’t like that the plagiarism checker tool is only available in the pro plan of QuillBot.
• Its grammar checker only corrects basic typos and grammatical errors and cannot catch more complex mistakes like dangling modifiers or incorrect punctuation.

Why we recommend QuillBot: It is a great choice for small businesses looking for a free grammar checker and paraphrasing tool.

2. Grammarly

Grammarly is a popular online grammar checker tool that can be used as a browser add-on for Google Chrome, Firefox, and even Microsoft Edge. The Grammarly website also offers a standalone tool option.

The tool detects and automatically corrects grammatical, spelling, and tonal errors directly in the WordPress block editor to improve sentence clarity.

Grammarly usually displays an indicator in the bottom right corner of the writing area. Clicking on it will show you the number of spelling, grammar, and contextual errors that will be highlighted with an underline as you write.

Pros

• The tool offers suggestions for sentence rephrasing, vocabulary suggestions, style checks, citation support, and more.
• It is the best plagiarism checker tool on the market.
• Grammarly is super beginner-friendly, and it will work well with minimal setup.
• In our experience, the AI-powered suggestions are often spot-on and help improve readability and clarity.

Cons

• Grammarly offers a free plan, but it is very limited. To get more advanced suggestions and error-checking, you will need to subscribe to the pro version.

• When testing, we noticed that the plagiarism checker does not work in the browser extension, so you will have to use the Grammarly website. This can be a drawback for some users.

Why we recommend Grammarly: We recommend Grammarly if you are looking for a tool that can detect grammatical errors, plagiarism, and other issues. If you have just started a WordPress blog, then you can opt for the free plan to detect basic errors.

3. Semrush

Semrush offers a couple of top-notch grammar checker tools. Each has a powerful set of features, including a readability checker that provides actionable tips for improving your content.

One tool is a free online proofreader that analyzes your blog post’s readability and tone of voice. It will suggest rewordings, instances to use a more active voice, and other ways to clarify and enhance your text.

Additionally, Semrush has an SEO Writing Assistant in their main product to improve the overall SEO score of your content.

You can use it to optimize your article headlines for SEO, adjust article length, perform a plagiarism check, and make your content sound more natural. We really like these features and recommend them to bloggers.

Both free and paid accounts can use the writing assistant, but paid accounts get many more features.

For more details, see our tutorial on how to use the SEO Writing Assistant to improve SEO in WordPress.

Pros

• Semrush comes with Microsoft Word, Google Docs, and WordPress add-ons that you can use to get real-time grammar suggestions in your WordPress content editor.
• It offers a free Paraphrasing tool where you can add your text, and AI will rephrase it for better readability and engagement.
• Semrush can catch your grammar, spelling, and punctuation errors in real time. It also addresses common errors like misused words, sentence fragments, and more.
• The SEO Writing Assistant provides a Flesch reading score and lets you compare your readability score with your top 10 competitors.

Cons

• Semrush’s free plan is pretty restricted. Some features are available to free users in a limited capacity, while others are entirely locked behind a pro subscription.
• We didn’t like that you must buy the tool to add it to your WordPress content editor.

Why we recommend Semrush: Semrush has two different grammar tools that work well together. Semrush’s SEO writing assistant and free proofreading tool give users access to a readability checker, proofreader, summary generator, sentence rewriter, and more. This combination makes Semrush a complete package to help improve your content quality.

4. Ginger

Ginger is another powerful spelling and grammar checker tool that can enhance your writing skills and boost productivity. It is available as a browser add-on and offers a great user experience.

Ginger comes with a sentence rephrasing tool that suggests other ways to express your ideas more clearly. It even has a personal dictionary where you can add custom phrases and words to help the tool understand your writing style.

Additionally, Ginger helps you identify clunky sentence structure by reading your blog posts out loud with natural pronunciation. This practice can make your content more engaging and natural for your audience.

Pros

• It displays a tiny icon where you can access the grammar checker features in the bottom right corner of writing areas, including WordPress post editor, Gmail, Facebook, and more.
• When researching, we found out that Ginger can translate your text in real time into over 60 languages.
• It comes with a text-to-speech feature, an emoji keyboard, and a thesaurus.

Cons

• Its free plan offers limited functionality.
• Upon reviewing customer reviews, we noticed that some users have reported glitches and bugs with the software.

Why we recommend Ginger: If you create and sell courses online, then Ginger’s grammar checker, rephrasing, and thesaurus tools can help you create concise and clear content for your students. It’s also a great option for multilingual websites due to its translation features.

5. Hemingway Editor

Hemingway is a free editor that you can use to check your articles for readability, grammar, and spelling errors. However, since it is web-based, it doesn’t work directly inside your WordPress post editor.

The tool shows you your content’s readability score and suggests improvements. The web app also has a clean and distraction-free layout, which can help you assess your content quickly before hitting the publish button in WordPress.

Hemingway uses different colors to identify various issues, making editing easier for users.

Pros

• The tool helps with passive voice detection, adverb usage, and formatting suggestions.
• It provides a word count and analyzes sentence structures for improvement.

• Hemingway is also available as a paid desktop app for both Windows and Mac, which allows you to post directly to WordPress.

Cons

• Hemingway often overly simplifies all the sentences in the content and sometimes removes the complex ideas completely.
• We didn’t like that the tool only supports the English language.
• It does not provide as much comprehensive grammar correction as other tools on the list.

Why we recommend Hemingway Editor: If you are an author on a WordPress site, then Hemingway can be a great choice due to its powerful readability checker. If you write technical topics and want to simplify the language for readers, then you can opt for this tool as well.

6. LanguageTool

LanguageTool is an amazing grammar and paraphrasing tool that is available as a free add-on for Chrome, Firefox, Google Docs, and LibreOffice. It is also available as a web-based editor and a complete desktop app.

LanguageTool supports more than 25 languages including English, German, Polish, and Russian, making it a great choice for multilingual websites and multilingual authors.

The software can detect grammatical errors, style issues, word choice, punctuation, and sentence structure issues.

Pros

• It has a text-to-speech feature.
• We love that the tool lets you create a personal dictionary.
• LanguageTool can also provide suggestions for typography.

Cons

• The free plan has a 20,000-character limit per text check.
• Its integration with tools like Microsoft Word and Google Docs can be a bit clunky.

Why we recommend LanguageTool: It is the ideal grammar checker if you have a multilingual website and want to check your content for grammatical errors in multiple languages.

Which Is the Best Grammar Checker Tool for WordPress?

In our expert opinion, QuillBot is the best grammar checker tool for WordPress users. It includes a grammar checker for multiple languages, a plagiarism checker, and even a summarizer to help you condense your content.

However, if you have a simple WordPress blog, then you can opt for Grammarly or Ginger instead. Both of these tools are reliable grammar checkers that come with a suite of other tools like paraphrasing, personal dictionaries, plagiarism checkers, and more.

Similarly, if you are on a budget, then Hemingway and QuillBot are also good choices.
