Grammar checkers help writers catch mistakes and reduce editing time. Check out our list of the best grammar checker software for Mac.
I love writing on Mac due to the wide range of writing apps and its rock-solid operating system. Although Mac comes bundled with a grammar checker, it doesn’t always suffice. I hate publishing my work only to spot typos later on. I’ve spent dozens of hours testing various grammar checkers, some of which work offline on a Mac while others require internet access.
In this post, I’ll profile the best grammar checker tools for Mac. I’ll detail their key features and explain if they suit your needs. Chances are you’re familiar with a few of my choices, but there is grammar software for all types of Mac users.

1. Mac’s Inbuilt Grammar Checker
If you’ve no budget or resources, the inbuilt grammar checker with Mac OS suffices. It won’t catch as much as other tools, but it’s free, and you can add words to your custom dictionary. It works fine and can spot spelling and grammar issues in apps like:
- Google Docs
- Microsoft Word
To set up your inbuilt Mac editor, head over to the Apple logo in the top-left-hand corner. Select system preferences > keyboard > text. Under the text heading, you’ll find a box that says “Correct Spelling Automatically.” Click this option, and you’re good to go.
2. Grammarly

Grammarly is the most popular grammar-checking app, and for a good reason. Founded in 2009, Grammarly upgrades its software every few months, resulting in one of the most accurate tools available.
Mac users can install Grammarly onto their computers. It then works like a popup, finding and fixing errors in any Mac writing app. Unlike the inbuilt Mac grammar checker, Grammarly for Mac spots grammar issues like:
- Clarity
- Spelling
- Engagement
- Delivery
It includes a plagiarism checker in the bottom-right-hand corner, so you won’t have to paste your work into a third-party tool. But the Grammarly feature that took my writing ability to the next level was its weekly emails. Grammarly sends emails notifying you about your most common mistakes while linking to articles that help.
It’s like your editor providing feedback that makes growing your writing skills straightforward. The best part is that you won’t have to hire a professional.
For example, when I started writing content, I’d use a lot of passive voice and weak adverbs that made my writing sound weak. Grammarly noticed this and sent me articles covering how to fix this problem. To learn more, read our Grammarly review.
3. ProWritingAid

ProWritingAid is another well-known grammar checker for Mac users. It’s accurate and spots advanced writing issues, so you can be sure your work is readable and clear.
It offers native support for Scrivener and additional reports that most tools don’t provide. These include:
- Cliches
- Diction
- Sensory
- Dialogue
- Structure
Unlike Grammarly, ProWritingAid contains a word-for-word analysis feature. This is helpful if you overuse certain words when writing articles. ProWritingAid spots overused words and provide synonyms, so your content reads better.
I find this valuable because overused words are something I struggled with at the beginning of my writing career. For example, instead of starting sentences with different words, I’d use “This” and “If” all the time, making my work sound awkward.
But with these reports, noticing repetitive words is easy, and I can get rid of them within a few rounds of edits. To learn more, read our ProWritingAid review.
4. Antidote


Antidote is tailored for businesses, students, and academic institutions because you don’t have to upload your work to a cloud or copy and paste it into an online tool. Instead, users can install Antidote on their Macbook or iMac and use it offline. No other grammar tool works like this.
This feature is handy if you’re sitting on the bus or train and want to make edits without internet access. The mobile app syncs to your computer when online, so the modifications you make on the go will be waiting for you on your desktop.
5. Ginger

Although Ginger doesn’t contain as many features as Grammarly or ProWritingAid, it’s still a suitable alternative for writers because it’s accurate and affordable. Ginger software operates similarly to Grammarly. Head over to their website and sign up for a free account, and from here, you’ll be able to check writing issues like:
- Sentence structure
- Clarity
- Overused words
- Spelling errors
But if you need more advanced features, consider signing up for the Ginger premium plan. It’s more affordable than Grammarly, and you receive a seven-day free trial. Then, contact customer support to get your money back if Ginger doesn’t meet your writing needs. Ginger also has a Mac desktop app, so you won’t have to go to the website to check content every time.
To learn more, read our Grammarly vs. Ginger comparison.
6. Linguix

Linguix is one of the best grammar checker tools because the AI is compatible with Mac and uses in-depth insights to improve your writing. This is why it’s widely used among bloggers, teams, and web publishers.
With the premium account, you’ll find convenient features like:
- Content shortcuts
- A content rewriter
- Research writing libraries
- Through writing analytics
The Linguix dashboard also contains a plagiarism checker and Chrome add-on, making plagiarism checking seamless.
So you won’t have to copy and paste your work into the web app when you’re finished writing. Instead, install the extension, and Linguix checks your writing for duplicate content in real-time.
For more, read our Grammarly vs Linguix comparison.
7. Quillbot

Let’s say a video you’ve posted online received thousands of views, and you’d like to repurpose this content into a blog post. But, first, you must copy the video script, paste it into the Quillbot spinning tool, edit the results, and publish it on your website. Although Quillbot doesn’t specialize in AI writing like Copy AI or Jasper, it’s surprisingly accurate.
If you’re a student and struggle to create accurate citations, the Quillbot citation generator is a must. Paste a reference title, link, date published, and choose the writing style. No other grammar checker handles citations as easily as Quillbot.
To learn more, read our Quillbot review.
8. Whitesmoke

Whitesmoke is a grammar checker that works online and offline, so it’s perfect if you don’t have access to the internet. The desktop and mobile apps are available on iOS, Android, Mac, and Windows devices. That said, it’s clunkier, older and slower than competitors.
Whitesmoke uses advanced algorithms to spot more than just basic spelling errors. After pasting your work, you’ll notice it detects:
- Passive voice
- Auxiliary verbs
- Incorrect capitalization
- To be verbs
- Style issues
But what’s unique about Whitesmoke is that they offer video tutorials on their website. These tutorials cover advanced writing topics, which is helpful for writers looking to take their content to the next level. For more, read our Grammarly vs Whitesmoke comparison.
9. Wordtune

Wordtune is grammar checker software that streamlines the entire editing process. It suggests ways to make your writing clearer and more relevant to your target audience.
For example, if your article covers the best video games, Wordtune will encourage a more casual tone to fit your audience. But if you’re writing about legal services for business owners, Wordtune uses a more formal approach.
With the extension, you won’t have to copy and paste your work into the app. Instead, it can make changes in Microsoft Word or Gmail.
If you’re creating content in languages other than English, Wordtune is still a practical option. It works in several languages like:
- Spanish
- Chinese
- Hindi
- Arabic
- Korean
This allows you to tailor your content to readers all around the world. Most of the other grammar tools for Mac here don’t support languages outside of US and British English.
For more, read our Wordune vs Grammarly comparison.
10. PaperRater

Founded in 2009, PaperRater is a proofreading software designed for students and anyone working in academia. It uses artificial intelligence to spot writing errors and help students score higher marks.
Since it’s built for students, it’s affordable compared to alternatives like Grammarly and ProWritingAid. PaperRater also offers a plagiarism checker, which helps students spot duplicate content and avoids penalties like disciplinary hearings. What caught my eye is that your first five plagiarism checks are free. So you can get a feel for the platform and its accuracy before investing in it.

11. Bartleby Write
Developed by Barnes & Noble Education, Bartleby Write is a student hub that promotes error-free writing. In addition, you’ll find tutors on the platform so you can learn about math, engineering, and science. This makes it ideal for high school and college students.
With Bartleby Write, you’ll access features like:
- Virtual tutoring
- Study resources
- Popular high school textbooks
So, while completing projects, go to the study resources page and ask for help. Bartleby Write offers resources in subjects like:
- Social science
- Engineering
- Science
- Math
- Business
Once you’ve completed your assignment, the writing assistant spots any grammar and spelling errors within seconds.

12. Scribens

Although free, a premium version removes all ads and raises the character limit to 200,000 characters or approximately 50 pages.
I also find that the explanations Scribens provides are helpful since they tell you what you did wrong and how you can improve for your next assignment.
13. Hemingway Editor

The Hemingway Editor is a free writing tool for Mac users. It gives you insight into the readability of your work. This makes it perfect for bloggers and freelance writers because a big part of grabbing a reader’s attention is writing content that’s easy to understand. You can either use it via the website or pay $19.99 for a version that works offline on Mac OS.
When you paste your work into the Hemingway Editor, you’ll find three areas that the software checks:
- Adverbs
- Passive voice
- Hard to read sentences
The adverb checker ensures you aren’t using unnecessary adverbs, and the passive voice tool is valuable when removing weak sentences. I also like that the Hemingway Editor spots hard-to-read sentences and prompts you to break them into two sentences or use smaller words. That said, Hemingway Editor won’t catch grammar errors. It’s useful for line editing only.
For more, read our Hemingway App review.
14. Language Tool

LanguageTool is another viable grammar checker for Mac that integrates with Google Docs, Microsoft Word, and multiple social media platforms. It also checks for writing issues in different languages like:
- Spanish
- German
- French
- Dutch
- Russian
Companies like Amazon and BMW even use the software to double-check their emails, marketing campaigns, and blog posts.
You’ll find zero distracting features on your dashboard, making it a practical option if you’re stuck in a creative rut. You type into this free grammar checker and enter a flow state within minutes.
15. Outwrite

Outwrite is a proofreader that mainly focuses on writing style issues. When pasting your work into Outwrite, it spots hard-to-read sentences, unnecessary commas, auxiliary verbs, and incorrect sentence structure.
The plagiarism checker is handy if you’re employing a few freelancers to create content for you. You can paste multiple articles into the software and receive a plagiarism score immediately.
For more, read our comparison of Outwrite vs Grammarly.
16. Microsoft Editor

If your primary Mac writing tool is MS Word or the Office 365 suite, you’ll be happy to know this software has a built-in checker. For example, the Microsoft Editor underlines your work in red as soon as you make a spelling error. And if you see a blue light, your content doesn’t read well.
But Microsoft introduced new features recently that took the software to another level. You’ll find features like:
- Clarity, style, and readability suggestions.
- Customizable writing tones.
- A Microsoft Editor browser extension.
Microsoft Editor works in over 30 languages, including Spanish, French, Italian, and Turkish. So it doesn’t matter what language you create content in; Microsoft Editor will be able to spot advanced writing errors.
For more, read our comparison of Microsoft Editor vs Grammarly.
What’s The Best Grammar Checker For Mac?
Our number one choice is Grammarly because it integrates with the Mac operating system and is exceptionally accurate and easy to use. We also like ProWritingAid due to its advanced reports. Antidote is a great grammar checker if you want to write an edit on Mac OS offline.
These options are perfect if you’re writing on a Macbook, iMac, or iPhone since they allow you to check for grammar on almost every platform. They are also accurate, so you can be sure they spot nearly all errors, from basic spelling mistakes to style issues and duplicate content.
Other grammar tools have a more limited feature set for Mac writers.
