Grammarly for Windows and Grammarly for Mac user guide

With the help of Grammarly for Windows or Grammarly for Mac, you can access our writing suggestions directly in a wide array of applications and websites.   

Before you install Grammarly for Windows or Grammarly for Mac, please make sure that your computer meets the system requirements for this app. 

This article covers: 

Checking text

Once the application is installed, open any app or website on your computer and start typing. You should then see a floating Grammarly widget on your screen. 

Grammarly checks your text dynamically as you write. Once Grammarly identifies a potential issue with the writing, it will automatically underline that word or phrase. You’ll also see a number of identified issues on the button:


When you’re ready to check your writing, click on the underlined word or the floating Grammarly widget to see the suggestions: 


Note: If you use Grammarly in Microsoft Word or Pages, you may see a slightly different interface with a list of suggestions. That interface allows you to review all suggestions offered by Grammarly and click on each to expand it.

To accept a suggestion, simply click on it. You can also learn more about each suggestion by clicking the three dots on the card.

If you don’t find a suggestion useful, you can dismiss it by clicking on the trash bin icon on the card. 

To switch to the next suggestion, click the arrow icon on the card. You can also click the specific underline in the text to see the suggestion.

Note: Some Grammarly checks, including the plagiarism checker, are not available in this product offering. If you’d like to check your document for plagiarism, we suggest using the Grammarly Editor instead.

Adding words to your personal dictionary

When checking your text, Grammarly may come across words specific to your writing style and that may not be widely used. If Grammarly doesn’t recognize these words, you can add them to your personal dictionary. Next time you use it in your text, Grammarly won’t flag it as a mistake.  

To add any word in your personal dictionary, go to, type the word into the corresponding field, and click the + button.  

Alternatively, if Grammarly identifies a particular word as misspelled, you will see a button visualized as a book on a suggestion card. This button also allows you to add the word to your dictionary.

Using Grammarly’s tone detector

Grammarly’s tone detector helps you understand how your writing may sound to its intended audience.

To check the tone of your message, make sure your writing contains at least 150 characters. You will then see an emoji directly on the floating Grammarly widget.  

Click the button to find out more about the tone of your message: 


You can also help us improve this feature by notifying us whether the tone of your message was detected correctly via the check or minus icon next to each tone. 

If you’d like Grammarly to stop checking the tone of your writing, click the floating Grammarly widget and then click the gear icon. In the Customization menu, switch off the Detect tone in my writing setting.

Deactivating certain suggestions

If you are a Grammarly Premium, Grammarly Business, or Grammarly for Education user, you can deactivate specific suggestions.

To do this, open your browser and go to and switch off a specific group of suggestions. This action will deactivate this group of suggestions in all of the Grammarly product offerings that you use. 

If you notice unhelpful suggestions, you can also dismiss them by following the steps in this section of the article. This helps us improve our algorithms.

Changing your language preference

Grammarly offers five dialect options: British English, American English, Canadian English, Australian English, and Indian English. By default, your language preference is set to American English, but you can change it anytime.

Here’s how to change your language preference in Grammarly for Windows or Grammarly for Mac:

  1. Click the floating Grammarly widget.
  2. Then, click the gear icon in the upper-right corner of the pop-up.
  3. Go to Writing Style and select your preferred option next to I write in

Alternatively, you can also go to directly and update your language preference there. Keep in mind that updating your language preference will apply the corresponding setting to all Grammarly product offerings you use.

Note: Grammarly doesn’t support other languages at this time.
