Grammarly

Although not directly integrated with Overleaf, Grammarly can provide language feedback for your Overleaf projects. This page offers some suggestions for using Grammarly with Overleaf, and how to disable it if needed. These suggestions are provided "as is" and do not represent official support for using Grammarly within Overleaf.

The Writefull AI-powered language assistant is fully integrated with Overleaf.

Known limitations

Our testing highlighted the following points:

1. Grammarly does not fully understand LaTeX markup, occasionally resulting in erroneous suggestions and words not being spell-checked.

2. In the Visual Editor, the error count reported by the Grammarly extension might be underestimated, particularly for large documents.

3. Browser extensions such as Grammarly can sometimes affect performance when working on long documents. If you are experiencing lag when typing or scrolling, try disabling Grammarly temporarily to test whether this improves the behavior.

Grammarly premium feature: Snippets

Users of Grammarly Premium have access to a “snippets” feature which, by default, is triggered using the backslash (\) character (as its shortcut). This feature could conflict with Overleaf’s autocomplete for LaTeX commands but, fortunately, the snippets shortcut character can be changed or disabled using advice from Grammarly support.
