selecting up to a threshold number of content objects to incorporate into the content digest.
9. The method of claim 1 , wherein the representative image for the selected content object is an avatar representing a sentiment associated with the selected content object.
10. The method of claim 1 , wherein the one or more slides are automatically generated at a predetermined time period.
11. The method of claim 1 , further comprising:
determining, for each retrieved content object, whether the content object is accessible by the user based on a privacy setting associated with the content object.
12. The method of claim 1 , further comprising ordering the one or more slides of the content digest based on one or more features associated with the respective slides.
13. The method of claim 12 , wherein the one or more features associated with the respective slides comprises one or more of: social signals associated with the content object corresponding to the slide; an affinity-coefficient of the user with respect to the content object corresponding to the slide; a relevance of the content object corresponding to the slide to the user; or a chronological relevance of the content object corresponding to the slide.
14. The method of claim 1 , further comprising:
receiving an indication of a gesture within a first slide of the one or more slides; and
providing instructions for presenting information associated with the selected content object associated with the first slide responsive to the gesture.
15. The method of claim 14 , wherein the information associated with the selected content object comprises an activatable link that is activatable to perform a context switch to the selected content object.
16. The method of claim 14 , wherein the information associated with the selected content object is presented on a second slide.
17. The method of claim 1 , wherein the one or more slides comprise an introductory slide that comprises information associated with a geographic location of the user.
18. One or more computer-readable non-transitory non-volatile storage media embodying software that is operable when executed to:
receive, by an assistant xbot, a user input in a first modality, wherein the first modality is an audio modality;
analyze, by a natural-language understanding module, the user input in the first modality to determine the user input comprises a request for a content digest;
retrieve one or more content objects corresponding to the request for the content digest;
determine, for each of the retrieved content objects, a representative image of the respective content object;
generate, for each of the retrieved content objects, a summary of the respective content object based on content of the respective content object;
generate one or more slides for the one or more retrieved content objects, respectively, wherein each slide comprises (1) the representative image of the respective content object and (2) the summary of the respective content object;
provide, by the assistant xbot, instructions for presenting the content digest in a second modality responsive to the request for the content digest from the user input in the first modality, wherein the second modality is a visual modality, wherein the content digest comprises the one or more slides, and wherein one or more of the slides of the content digest are removed from the content digest after a predetermined time period;
