To remove Grammarly extension Safari, you must uninstall the associated "Grammarly for Safari" application from your Mac's Applications folder, not just disable it in Safari's settings. This is the only way to completely remove the software and its background processes from your computer.
How to completely remove the Grammarly extension from Safari
Before attempting to uninstall, ensure the Grammarly application is not actively running. To quit Grammarly, click its icon in the Mac menu bar (typically in the upper-right corner of your screen) and select "Quit." After ensuring the application is quit, open Finder and navigate to the "Applications" folder. Locate the "Grammarly for Safari" or "Grammarly Desktop" application within the Applications folder. Drag the "Grammarly for Safari" application to the Trash (or Bin). You may be prompted to enter your computer's password to confirm the deletion. Once the application is in the Trash, empty the Trash to complete the uninstallation. Simply disabling the extension within Safari's preferences without removing the associated application from the Applications folder may not constitute a complete uninstallation of Grammarly.
How to temporarily disable Grammarly in Safari
If you only want to stop Grammarly from working in Safari without fully removing the software, you can disable the extension through Safari's settings. This is a non-permanent method that leaves the Grammarly application and its background processes running on your Mac. To manage extensions directly within Safari, open Safari, go to "Safari" > "Settings" (or "Preferences"), and click on the "Extensions" tab. In Safari's Extensions settings, you can uncheck the box next to Grammarly to temporarily deactivate it. This stops Grammarly from checking your text in Safari, but the application remains installed and can be re-enabled at any time by re-checking the box. If you are also tidying up your browser, you can similarly delete tab groups in Safari to keep your workspace organized.
System requirements for Grammarly on Safari
Understanding the system requirements helps explain why some users may encounter different experiences when trying to remove or use the extension. Grammarly for Mac requires macOS 11 (Big Sur) or newer and Safari version 12.1 or newer to function. The Grammarly extension for Safari on iPhone is available on devices running iOS 17 or newer. If you are using an older operating system or Safari version, Grammarly may not have been fully functional, and the uninstallation process may differ slightly due to the absence of the desktop application component. If a stubborn extension icon remains in your toolbar, you may also need to remove puzzle piece from Safari.
