Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for using artificial intelligence to display responses and digital components in a conversational user interface. A method includes initiating a user session with a conversational user interface of an artificial intelligence system. During the user session, the method includes receiving, by the artificial intelligence system, one or more prompts; displaying, in the conversational user interface, one or more digital components that each include content related to a corresponding item based at least in part on the one or more prompts, detecting, for each displayed digital component, one or more user interaction events; updating a user interest record, and displaying one or more additional digital components in the conversational user interface based at least in part on the user interest record.
