Group contact lists generation

A server system, comprising:

• one or more processors;
• and
• a memory storing instructions that, when executed by the one or more processors, configure the server system to perform operations comprising:
• receiving, at a server computer from a client device, a plurality of contacts, the plurality of contacts each associated with a respective contact digital interface of plurality of contact digital interfaces;
• analyzing, by the server computer, the plurality of contact digital interfaces to identify a first set of contacts in the plurality of contacts that include a modification to each of a respective contact digital interface, the modification comprises a change to a digital expression object and the digital expression object comprises an avatar, emoji, emoticon, or image;
• generating a first group contact interface comprising the modification;
• generating a new group contact list that comprises the first set of contacts;
• associating the first group contact interface with the new group contact list;
• causing the first group contact interface to be displayed by the client device;
• analyzing, by the server computer using machine vision, the plurality of contact digital interfaces to identify a second set of contacts in the plurality of contacts, the second set of contacts do not include the modification;
• generating a second group contact interface that includes the second set of contacts;
• and
• causing the second group contact interface to be displayed by the client device, wherein a portion of the second group contact interface is overlaid over a portion of the first contact group interface.

A non-transitory computer-readable storage medium, the computer-readable storage medium including instructions that when executed by a computer, cause the computer to perform operations comprising:

• receiving, at a server computer from a client device, a plurality of contacts, the plurality of contacts each associated with a respective contact digital interface of plurality of contact digital interfaces;
• analyzing, by the server computer, the plurality of contact digital interfaces to identify a first set of contacts in the plurality of contacts that include a modification to each of a respective contact digital interface;
• generating a first group contact interface comprising the modification;
• generating a new group contact list that comprises the first set of contacts;
• associating the first group contact interface with the new group contact list;
• causing the first group contact interface to be displayed by the client device;
• analyzing the plurality of contact digital interfaces to identify a second set of contacts in the plurality of contacts, the second set of contacts do not include the modification;
• generating a second contact group interface that includes the second set of contacts;
• and
• causing the second contact group interface to be displayed by the client device, wherein a portion of the second contact group interface is overlaid over a portion of the first contact group interface.
