How to Set up LanguageTool in LibreOffice

A quick tutorial on how to set up the free LanguageTool in LibreOffice to check spelling and grammar.

LanguageTool is a popular multi-multilanguage spelling, style and grammar checker which helps you to correct and paraphrase texts. It’s one of the best “free” alternatives to Grammarly – which is also a popular service.

It comes with two options. The free option comes with basic style, grammar, semantics, and a few preliminary features. And the premium version gives you more options.

LibreOffice, which is the most popular free and open-source application, brings built-in capability to connect to LanguageTool server and give you grammar-checking capabilities.

Let’s find out how.

Set up LanguageTool in LibreOffice

  • Open LibreOffice (any module such as Writer, Calc, etc.)
  • From the menu, select Tools > Options. For macOS users, choose LibreOffice > Preferences.
  • On the options window, select Language Settings > LanguageTool Server. This option is available on LibreOffice 7.4 and above.
  • Select the checkbox Enable LanguageTool.

You can generate this yourself by clicking on โ€œAccess tokenโ€ in the settings of the LanguageTool Editor. There you will find the option for LibreOffice.
