User Guide: Getting Started

Opening Grammarly

Just click the Open Grammarly button in the Home tab or use the button in your new Grammarly tab, and the Grammarly sidebar will appear.


Specifying check types

Once you open Grammarly, you'll be brought to the Grammarly tab to specify which of our four categories of suggestions you want to run on your document.

To make sure Grammarly checks your document for correctness, clarity, delivery, and engagement, please click All Issues. To enable only one category, just click on it. Grammarly suggestions will be shown directly in the sidebar.
