Categories and FAQs can be added in multiple languages. Freshchat currently supports 32 languages. It uses the user locale settings to determine the language in which the FAQs are to be displayed to a user.
In case of mobile users, the locale can be identified from the app or the user device. The app’s user locale takes priority over device’s user locale. 

For web users, Freshchat uses the browser’s locale. This helps to ensure that the FAQs are always delivered to the user in their language. 

However, if the language for a user locale hasn’t been added / enabled in the Languages section of Admin, then the FAQs will be displayed in the pre-configured Primary Language.
