Can I use Overleaf with language checking tools, such as Grammarly?

The LanguageTool browser add-on/plugin works with the Overleaf editor. This provides a language and grammar checker which allows you to check your text for grammatical errors. You can download/install the add-on for Firefox or Chrome.

After installing the add-on, highlight some text in the Overleaf editor which you'd like to check, and then click on the LT button in your browser's tool bar. The add-on will then list possible problems it found in the selected text.
