# Engage

Engage groups the tools used to reach and test content with specific audiences, separate from the core content-management tools like Websites, Modules, Forms, and Documents. It sits in the left navigation right after those.

Each entity below follows the same pattern as Organization: an **Add** page to create a new one, and an **Overview** page — opened by clicking an existing item in its list — for adding entries, editing, and permissions.

**Name** | **Description**
:--- | ---
[Segments](/engage/segment/) | Group contacts by shared criteria so content and campaigns can target a specific audience.
[File Groups](/engage/file-group/) | Manage and display a related set of files together, with their own permissions.
[Scheduler](/engage/scheduler/) | Automatically swap a page's content in and out on a predefined schedule.
[Experiments](/engage/experiment/) | Run A/B tests between different versions of content and track which one performs better.
