# Languages

SitecoreAI supports creating content and websites in multiple languages.
The default language is English, but you can [add](https://doc.sitecore.com/xmc/en/users/xm-cloud/manage-languages-and-locales.html) any number of languages to your environment, languages that you can select amongst the predefined languages that are supported by SitecoreAI.
Sitecore supports all the languages available in the .NET CultureInfo class.
A predefined language in SitecoreAI follows the ISO code and combines both language and country or region, for example, en-AU or English(Australia).
