Which feature is utilized for managing multiple languages within AEM?

The Multi-site Manager is the feature utilized for managing multiple languages within AEM. This tool allows organizations to efficiently create, maintain, and manage content across various locales or regions, facilitating the localization process. It provides a centralized way to handle multiple sites and languages, ensuring a consistent user experience while also allowing for customization where necessary.

By utilizing the Multi-site Manager, businesses can efficiently implement language variations for their content, enabling them to tailor their offerings to different markets while streamlining their content workflow. This is particularly valuable for enterprises that need to manage large amounts of localized content across different versions of their websites for diverse audiences.

While other options like the Translation Management Tool and the Experience Translation Service are also related to translation and content management, they serve different purposes, such as specifically handling translation processes or integrating translation services. The Content Synchronization Tool focuses on keeping content in sync across environments rather than directly managing language variations. Hence, the Multi-site Manager is the most appropriate feature for this task.
