Structured rich content inside a chat turn
Link previews, search results, booking-style responses. A message card gives rich content a quiet frame inside an assistant turn or bubble: media on top, a title and description in the body, actions in a footer. It is not the navigation Card. That one is a large-radius tile you click to go somewhere; this one is content furniture the conversation scrolls past.
Anatomy
An optional icon leads the title, a free-text meta line carries a domain or date in your own formatting, and the description stays to a line or two.
Link previews
The classic unfurl. The actions footer sits outside the body, mirroring the tool call footer, so link actions and approvals read as the same row across the ai components.
With media
The media slot renders flush to the card edges with no padding of its own; the card clips it, so the corners round themselves.
Inside a message
The intended habitat. The card claims no width of its own, so the turn that holds it sets the measure.
