Grammarly's browser extension user guide

Grammarly offers a browser extension for Chrome, Safari, Firefox, and Edge. The extension works on popular websites and can help you check your text whenever you write online. 

Note: If you also use Grammarly for Windows and Mac, the browser extension will be turned off by default but will remain active in Google Docs. For more information on how to use Grammarly in Google Docs, check out this page

To check whether the extension is installed, take a look at the top bar of your browser. If the extension is active, you’ll see the Grammarly icon:


Note: If you use Chrome, you can pin Grammarly’s browser extension to your toolbar for easier access. To do that, click the puzzle icon in the upper-right corner of the browser window and then click the pin icon to add Grammarly to your toolbar. 

Once the extension is installed, you should see Grammarly’s writing suggestions as you type on different websites.  

This article covers the following topics: 

Checking text

When you click into a text field, you should see Grammarly’s logo in the lower-right corner. As you start typing, Grammarly will begin to check your text dynamically, and the Grammarly icon will spin. 

Note: Grammarly does not initialize in text areas smaller than 38 pixels in height. 

When Grammarly finishes checking the text, the icon in the lower-right corner of the text field will show the number of suggestions: 


Some of our suggestions appear as underlines directly in the text. To accept a suggestion, hover over the underlined text, then click on the suggestion that appears:

If Grammarly flags an unfamiliar word and you’re sure it’s spelled correctly, you can either dismiss the suggestion by clicking Dismiss or add the word to your personal dictionary by clicking the book icon. 

Note: If you use Grammarly for Business or Grammarly for Education, the list of suggestions will appear in a sidebar once you click the Grammarly icon in the lower-right corner of the text field.
