Best Grammar Checker For Mac: 16 Top Options (2024)

Discover what the best grammar checker apps for Mac are, both free and paid in our round-up.

I love writing on Mac due to its rock-solid operating system and wide range of writing apps. 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 working offline on a Mac while others requiring internet access.

In this post, I’ll profile Mac’s best grammar checker tools. 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.

If you’re a rush, the best grammar checker for Mac is Grammarly, as it’s easy to use and includes an AI writing assistant.

1. Mac’s Inbuilt Grammar Checker

Mac's Inbuilt Grammar Checker
Mac OS grammar-checker is free and can spot spelling and grammar issues

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
  • Facebook
  • 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

Grammar Checker For Mac: Grammarly
Grammarly is a good choice for fixing mistakes. It integrates with Mac OS

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.

  • The weekly emails allow you to grow as a writer.
  • It spots advanced clarity and structural writing errors.
  • You can check for plagiarism while correcting grammar errors.
  • The plagiarism checker isn’t as detailed as other tools like Copyscape and

3. ProWritingAid

Prowritingaid new UI
ProWritingAid has accurate and spots advanced writing issues

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 eliminate them within a few rounds of edits. To learn more, read our ProWritingAid review.

  • The word-for-word analysis gives you an in-depth view of your writing.
  • It offers reports for diction, cliches, and structure.
  • ProWritingAid is compatible with most writing tools.
  • It takes a while to get used to the interface.

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

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.
