• detecting a first content link in the message, and automatically designating the detected first content link for syndication;
• storing the first content link in a local link index;
• receiving, by a first process executing on an electronic device and from a second process executing on the electronic device, a request for links to content items that resolve to the content items in the second process;
• obtaining, based on the request, by the first process and from the local link index comprising links to different content items associated with different processes, a plurality of links to content items that resolve to the content items in the second process and associated metadata, wherein the local link index is locally stored on the electronic device;
• and
• providing, by the first process, the plurality of links to the content items obtained from the local link index for presentation by the second process, wherein selection of one of the plurality of links causes the second process to present a content item associated with the selected link.

A device, comprising:

• a plurality of computer programs;
• and
• a link index comprising links to content items communicated via a messaging application of the plurality of computer programs, each respective link being stored with respective associated metadata that indicates a respective one of the plurality of computer programs associated with the respective link;
• and
• one or more processors configured to execute instructions of the plurality of computer programs to:
• receive a message from a participant in a first conversation thread of the messaging application;
• detecting a first content link in the message, and automatically designating the detected first content link for syndication;
• storing the first content link in the link index;
• receive, by an application of the plurality of computer programs executing on the device and from a client application of the plurality of computer programs executing on the device, a request for links to content items that resolve to the content items in the client application;
• obtain, based on the request, by the application and from the link index, a plurality of links to the content items that resolve to the content items in the client application and associated metadata;
• and
• provide, by the application, the plurality of links to the content items obtained from the link index for presentation by the client application, wherein selection of one of the plurality of links causes the client application to present a content item associated with the selected link.
