Saga is an Artificial Intelligence private assistant in a Smartphone app. She has a sassy, sometimes rude, attitude. No subservient slave here.
Saga (pronounced say-gah) is named after Saga Norén, the main character in the Swedish TV series the Bridge, available on Netflix and well worth watching. The TV Saga is a human who tends to act like a robot. Saga, the app, is a robot who tends to act like a human.
Created by Chandler Gray in the novel Tiger and the Robot, available on Amazon Books and Kindle. Originally a personal assistant for a Private Detective, her capabilities have proven useful in everyday life.
The Saga App exists, but is no longer available to the public, due to privacy issues.
