Artificial Intelligence (A.I.s) are highly intelligent, sentient, or semi-sentient entities that exist within computer systems. They are created to operate more complicated machinery and devices, such as robots.
Artificial Intelligences were normally limited to devices such as robots or other computer systems. The majority of A.I. are intelligent enough to continue their pre-war functions and are normally hostile to ponies that they detect. The Crusader Maneframes possessed extremely powerful A.I.s and were capable of processing vast amounts of information quickly or even containing a pony's knowledge and personality.
