Checking text
To access Grammarly’s suggestions in Google Docs, create or open a Google document and click the Grammarly button in the lower-right corner of the browser window. This will open the Grammarly sidebar.
If you’d like to accept a suggestion, simply select the suggestion card within the sidebar and click on the proposed changes.
To see a detailed explanation of the suggestion, click Learn more at the bottom of the suggestion.
If a suggestion is incorrect or you’d like to report it for any reason, click the three dots and choose your preferred option to proceed.
If you’d like Grammarly to stop flagging a particular spelling as incorrect, you can add the word to your personal dictionary by clicking Add to Dictionary within the suggestion card.
Some suggestions, such as correctness suggestions (red underlines) or style guide suggestions (gray underlines, available to Grammarly Business users), are shown directly in the text. You don’t have to open the sidebar to accept these suggestions — simply hover over the underlined word to see the suggestion card.
