## How to use Grammarly with Overleaf

Follow these steps to use Grammarly with Overleaf:

1. Install a [browser extension provided by Grammarly](https://support.grammarly.com/hc/en-us/articles/115000091552-How-to-instal). We refer readers to [Grammarly’s support pages](https://support.grammarly.com/hc/en-us/articles/115000091592-How-does-the-Gramma) for further information.
2. You will require a [Grammarly account](https://www.grammarly.com/plans).

Here’s a screenshot showing the Grammarly extension for Chrome pinned to Chrome’s toolbar:

* Note: To avoid potential conflicts with Grammarly’s suggestions, you may wish to switch off Overleaf’s built-in spell check via the project’s **Settings**:

The Grammarly extension will always check the file that’s currently open in the editor, and it will present itself at the bottom of the document.

## 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.&#x20;
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](https://support.grammarly.com/hc/en-us/articles/4403077145485-Introducing-snippets#h_01FNP7HWZAR3E7EMXS6N539QS6) 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](https://support.grammarly.com/hc/en-us/articles/4403077145485-Introducing-snippets).
