Technologies for contextual platform recommendations including a computing device with a number of platform capabilities, including any combination of hardware capabilities and software capabilities. The computing device stores context data based on the current context of the computing device and determines a user profile based on the context data. The user profile is indicative of typical behavior of the user of the computing device. The computing device determines a recommended platform capability from a number of available platform capabilities based on the user profile. The computing device notifies the user of the recommended platform capability. The computing device may also provide the notification only when the recommended platform capability is relevant to the current device context. The computing device may transmit the user profile to a recommendation service, which may generate additional recommendations for platform capabilities. Other embodiments are described and claimed.
