Systems and methods are presented for providing dynamic summaries of missed content of content streaming on multiple device. A plurality of groups for a concurrent presentation of a content is identified, and a selection is received by a user via a second device to join a first group of the plurality of groups for the concurrent presentation of the content. Based on a user via the second device joining a group, a determination is made as to whether a user via the second device missed any content from the concurrent presentation of the content for the first group. Based on the detection of missed content, the system generates for the second device one or more summaries of the missed content segments and the missed reactions to the segments based on preferences associated with the user profile. In response to generating the summaries, the summaries are presented via the second device to the user.
