Grammarly can integrate with Microsoft Word through an Office add-in or through the Grammarly desktop application. Disable the component that is actually generating suggestions rather than changing Word’s unrelated proofing features.
Steps
- Close documents containing unsaved work.
- In Word, open File > Options > Add-ins.
- If Grammarly appears as an Office add-in, use the appropriate Manage control to disable or remove it.
- If Grammarly suggestions instead come from the desktop application, open Grammarly and disable its Word/application integration or quit Grammarly.
- Restart Word.
- Type a short test sentence and confirm Grammarly suggestions no longer appear.
Microsoft Editor is separate
Word has its own spelling, grammar, and Microsoft Editor features. Those suggestions can continue after Grammarly is disabled because they are controlled through Word’s proofing settings.
Disable versus uninstall
Disabling an add-in is useful when you may want it again later. Uninstalling Grammarly is a broader change and can affect its integration with browsers and other applications.
Managed installations may return
A workplace or school can deploy Office add-ins or desktop software centrally. If Grammarly reappears after you remove it, check organizational policy rather than repeatedly deleting managed components.
Troubleshoot performance selectively
If you are disabling Grammarly because Word is slow or unstable, test Word after the change before removing other add-ins. Changing one integration at a time makes it easier to identify the actual cause.
