CALO was an artificial intelligence project that attempted to integrate numerous AI technologies into a cognitive assistant. CALO is an acronym for "Cognitive Assistant that Learns and Organizes". The name was inspired by the Latin word "calonis," which means "soldier’s servant". The project started in May 2003 and ran for five years, ending in 2008. The CALO effort has had many major spin-offs, most notably the Siri intelligent software assistant that is now part of the Apple iOS since iOS 5 in the iPhone 4S, iPhone 5, iPod Touch 5 and the New iPad; Social Kinetics, a social application that learned personalized intervention and treatment strategies for chronic disease patients, sold to RedBrick Health; the Trapit project, which is a web scraper and news aggregator that makes intelligent selections of web content based on user preferences; Tempo AI, a smart calendar; Desti, a personalized travel guide; and Kuato Studios, a game development startup.
