Abstract: Methods, systems, and media for presenting a user interface customized for a predicted user activity are provided. In some embodiments, the method comprises: selecting users of a content delivery service, causing user devices to prompt the associated users to provide subjective data related to the user's intent when requesting media content items, training a predictive model to identify a user's subjective intent in requesting a media content item based on objective data received from a user device associated with the user and the subjective data received from the user devices, wherein the predictive model is trained to identify whether to present the user with a first user interface associated with a first user intent or a second user interface associated with a second user intent, causing the first user interface or the second user interface to be presented.
