How to install a Grazie spell-check language pack in an offline environment

October 27, 2026 06:25 Updated

Background/Situation

JetBrains IDEs use the Grazie plugin for natural language spell and grammar checking. By default, language packs are downloaded automatically when a language is added in Settings. In offline environments where the IDE cannot reach resources.jetbrains.com, the language pack must be installed manually.

Question

How to install a Grazie spell-check language pack (for example, French) in an IDE that has no internet access?

Answer

On a machine with internet access, download the language pack .jar from the JetBrains resources server. The URL has the form:
```
https://resources.jetbrains.com/grazie/model/language-tool/<version>/<lang>-<version>.jar
```
For example, French version 6.7.20: fr-6.7.20.jar.
Locate the IDE configuration directory.
Inside the configuration directory, create the subfolder grazie/<lang>-LT<version>/. Create the parent folders if they do not exist. For French 6.7.20, the path is:
```
<config-directory>/grazie/fr-LT6.7.20/
```
Copy the downloaded .jar file into that folder.
Restart the IDE.
Open Settings (Ctrl+Alt+S on Windows/Linux, ⌘, on macOS) | Editor | Natural Languages, click Add, and select the installed language (for example, Français).

The language is now available for spell and grammar checking.
