A method at a computing system includes: receiving a request from a user; and in response to the user request: identifying a first media content item playing on a first client device concurrently with the user request, identifying a playback position in the first media content item temporally proximate to the user request, identifying a reference to an entity within a content portion of the first media content item, where the content portion corresponds to the identified playback position, identifying an event associated with the referenced entity, and setting a reminder of the event for the user.
