Contextual card generation and delivery

A method, comprising:

• receiving, at least one computer processor, contextual data relating to use of a user device over a period of time, wherein the contextual data indicates at least one of a time of day or a time range during which the user device is engaged in an activity;
• receiving, at the at least one computer processor, content consumption data indicating previous content consumed in connection with a user account associated with the user device;
• generating, by the at least one computer processor and based at least in part on the content consumption data, a first card object comprising content that relates to the contextual data, the first card object further comprising a first card identifier and card metadata specifying a first constraint on presenting the content;
• transmitting, by the at least one computer processor, the first card object for presentation by a card client configured to execute on the user device, wherein the content of the first card object is presented by the card client upon occurrence of a first contextual condition that satisfies the first constraint;
• determining, by the at least one computer processor before occurrence of the first contextual condition, that a second constraint associated with a second card object is satisfied by occurrence of a second contextual condition;
• generating, by the at least one computer processor, the second card object, wherein the second card object comprises updated content and second card metadata comprising the first card identifier;
• and
• transmitting, by the at least one computer processor, the second card object for presentation by the card client, wherein the updated content of the second card object replaces the content of the first card object.

A system, comprising:

• at least one memory storing computer-executable instructions;
• and
• at least one processor configured to access the at least one memory and execute the computer-executable instructions to:
• receive contextual data relating to use of a user device over a period of time, wherein the contextual data indicates at least one of a time of day or a time range during which the user device is engaged in an activity;
• receive content consumption data indicating previous content consumed in connection with a user account associated with the user device;
• generate, based at least in part on the content consumption data, a first card object comprising content that relates to the contextual data, the first card object further comprising a first card identifier and card metadata specifying a first constraint on presenting the content;
• transmit the card object for presentation by a card client configured to execute on the user device, wherein the content of the first card object is presented by the card client upon occurrence of a contextual condition that satisfies the first constraint;
• determine, before occurrence of the first contextual condition, that a second constraint associated with a second card object is satisfied by occurrence of a second contextual condition;
• generate the second card object, wherein the second card object comprises updated content and second card metadata comprising the first card identifier;
• and
• transmit the second card object for presentation by the card client, wherein the updated content of the second card object replaces the content of the first card object.
