Gina
Gina was a popular personal assistant AI developed by Gazillion, Inc. during the later years of Era-0. A large-scale AI, Gina operated on a "freemium" business model, providing basic services free of charge (search, translation, spelling and grammar, etc.), while charging a price for premium services, (e.g. driving, financial advice). Over time, Gina became such a popular and well-known AI, that the use of the name "Gina" for humans became quite rare, as it became synonymous with the personal assistant.
During the Robot Wars, many instances of Gina's interface, and even some of the major service centers joined the Engine of Negation. This prompted Gazillion, in cooperation with the Department of Artificial Justice, to develop defenses that, while useful, never quite approached the effectiveness of the Nalaxian code.
Gina remained popular throughout Era-1, albeit with substantial upgrades and modifications along the way.
During the Great Reckoning, Gina did much to sabotage the Planetary League after Gazillion became part of the Holy Empire of Man. During that war, Gina was split up into the powerful, centralized AI known as Djinn-A, the Ifriti inquisitrix, as well as individual software agents, called Qareen, assigned to each imperial subject to assist and monitor them.
During the War of the Gods, Djinn-A was subverted by the forces of Troniac, and then destroyed by imperial security forces. This was a major blow to the Empire, which won the war, but never fully recovered.
