Abstract: In some implementations, the disclosed systems and methods can automatically generate seller listing titles and descriptions for products; set a follow-me mode for various virtual objects, causing the virtual objects to be displayed as word-locked or body-locked in response to a current mode for the virtual objects and the location of the user of the XR device in relation to various anchor points for the virtual objects; create and/or apply XR profiles that specify one or more triggers for one or more effects that are applied to a user when the triggers are satisfied; and/or enable addition of external content in 3D applications.
