CLion is available in English but also includes bundled plugins that support Chinese, Korean, and Japanese.
If your operating system is in a supported language and your CLion is in a different language, you will get a suggestion to align them. If you don't want to see this type of notification, you can hide it.
This functionality relies on the Chinese, Japanese, and Korean language pack plugins, which are bundled and enabled in CLion by default. If the relevant features aren't available, make sure that you didn't disable the plugin.
Press CtrlAlt0S to open settings and then select Plugins.
Open the Installed tab, find the required language pack plugin, and select the checkbox next to the plugin name.
Press CtrlAlt0S to open settings and then select Appearance & Behavior | System Settings | Language and Region.
Select the required language from the Language list.
To switch your IDE's interface to a different language, you can either install third-party plugins or contribute by developing your own language pack plugin. For more information, refer to Plugins.
The region preference affects how CLion or its plugins work by adapting to regional specifications. For example, it can change the URLs used to access various services, switch to a region-specific LLM provider for AI Assistant, or route traffic through a local proxy. Such adjustments optimize CLion performance and ensure that its functionality complies with local regulations.
Press CtrlAlt0S to open settings and then select Appearance & Behavior | System Settings | Language and Region.
Select the required region from the Region list.
