Abstract: A system and method to generate personalized user interfaces are provided. The system may determine one or more items of demographic content associated with at least one user to obtain one or more user attributes. The system may determine one or more signals associated with a communication device associated with the at least one user or one or more user activities associated with the communication device or associated with at least one application associated with the communication device. The system may generate, based on the determined user attributes and the determined one or more signals, a first user interface, including content items and one or more elements, that is tailored or personalized to the at least one user.

Abstract: In one embodiment, a method includes identifying a particular item of interest of a user; determining a grouping of a number of items that are similar to the particular item; automatically creating a new video by combining the particular item and the respective number of grouped items that are similar to the particular item in accordance with a video-creation template; and providing the created video for display on a client device of the user.
