# Automatic Application User Mapping to GRAVITY Audiences
The idea behind GRAVITY's [[Audiences]] is to limit the visibility of a Callout/Hotspot to certain users. You can build Audiences manually or by a rule set.
GRAVITY can take advantage of automatic user mapping to audiences using the target applications user roles. By leveraging role information from such applications, users are automatically placed into the relevant audience, simplifying the process of audience creation and maintenance.
The configuration for Automatic Application User Mapping is done within the application settings rather than at the site level. To set up, go to Applications, select the application you wish to configure for editing, and navigate to the Audience Automapping tab.
