Are you looking for the best online grammar checker tools for your WordPress website?

Most web browsers come with a built-in spellcheck tool. However, they don’t check for grammar errors and readability.

In this article, we have hand-picked the best online grammar checker tools that you can use with WordPress.

Best Online Grammar Checker Tools for WordPress

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. It 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.

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

Note: When choosing grammar checker tools for this article, we tried each of these tools in our browser and test website. This helped us explore all the features, pros, and cons to provide you with the best recommendations.

Semrush is the best grammar checker tool on the market. It comes with a powerful set of features, including a readability checker that provides actionable tips to improve your content.

The tool also offers a free online proofreader that ranks your blog post’s readability and tone of voice. It then suggests using more active voice, fewer pronouns, avoiding generic intensifiers, and more.

  • The SEO Writing Assistant provides a Flesch reading score and lets you compare your readability score with your top 10 competitors.


  • Semrush does not have a free plan. If you want to add the tool to your WordPress content editor, you must buy it.

Semrush also offers an SEO writing assistant, readability checker, proofreader, summary generator, sentence rewriter, and other powerful tools. This makes Semrush a complete package to help improve your content quality.

2. Grammarly


Grammarly is a popular online grammar checker tool that is available as a browser addon for Google Chrome, Firefox, and even Microsoft Edge.

The tool detects and automatically corrects grammatical, spelling, and tonal errors directly in the WordPress block editor and improves your 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.

  • Grammarly is super beginner-friendly.


  • Grammarly offers a free plan, but it is very limited. You will need to switch to the pro version to get more advanced suggestions.
  • The plagiarism checker does not work in the browser extension, so you will have to use the Grammarly text editor.

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

3. Ginger


Ginger is another powerful spelling and grammar checker tool that you can use to enhance your writing skills and boost productivity. It is available as a browser addon 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.

  • It comes with a text-to-speech feature, an emoji keyboard, and a thesaurus.


  • Its free plan offers limited functionality.

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.

4. 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.

  • 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.

5. Hemingway Editor

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 a readability score of your content 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.


  • 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.


  • Hemingway often overly simplifies all the sentences in the content and sometimes removes the complex ideas completely.
  • It 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 robust 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.

  • It lets you create a personal dictionary.
  • LanguageTool can also provide suggestions for typography.


  • 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, Semrush is the best grammar checker tool for WordPress due to its easy integration with the software and numerous features like an SEO Writing Assistant, proofreader, paraphrasing tool, and more.

The tool easily fixes grammatical errors and effortlessly boosts your content’s SEO and readability.

However, if you have a simple WordPress blog, then you can opt for Grammarly or Ginger instead. Both of these tools are robust 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.

    I have utilized Grammarly “Premium” and as for me, it is currently one of the best grammar checker tools.

  3. Dan says

    Hemingway doesn’t check grammar, just style. Two other major ones you seem to have missed are WhiteSmoke and ProWritingAid. AfterTheDeadline is no longer being developed so is pretty old.

  4. Sandeep Parihar says

    Best and essential list of grammar checker tools I use Grammarly and its the best tools thanks for the sharing this list.

  5. Dane says

    You always have interesting articles. This article was also quite informative. Yet, I am still confused as to which one you would consider to be the best of the best. It seems that no matter which one I would chose I would still have to do something extra to review my writing. I thought I would only have to install the program and start writing while everything I would write would be instantly put into the proper context. Is that the case? Thanks again for all your knowledge you pass on. Dane

    I have been using Grammarly for quite some time and I do not think it is very good. It works but it does not find all of the misspelled words on my blogs. I mostly use the text editor and do my own coding. Often I have to check Google to see if I have spelled a word correctly. Sometimes it picks up on a “misspelling” that is not spelled wrong. If I switch to visual editor it will pick up on a few that it didn’t find in the text editor.

    I was hoping to find something better. If it is the “best” then I guess I’ll have to keep looking for something better to be created. LOL.

  7. Brenda Colbath says

    I have Grammarly on my machine. Does it only work if I am on a paid site? I haven’t noticed it working when I post.
