SRI International
In December 2007, SRI launched a spin-off company, Siri Inc., which Apple acquired in April 2010. In October 2011, Apple announced the Siri personal assistant as an integrated feature of the Apple iPhone 4S. Siri's technology was born from SRI's work on the DARPA-funded CALO project, described by SRI as the largest artificial intelligence project ever launched. Siri was co-founded in December 2007 by Dag Kittlaus (CEO), Adam Cheyer (vice president, engineering), and Tom Gruber (CTO/vice president, design), together with Norman Winarsky (vice president of SRI Ventures). Investors included Menlo Ventures and Morgenthaler Ventures.
MacOS
In more recent releases, Apple has developed support for emoji characters by including the proprietary Apple Color Emoji font. Apple has also connected macOS with social networks such as Twitter and Facebook through the addition of share buttons for content such as pictures and text. Apple has brought several applications and features that originally debuted in iOS, its mobile operating system, to macOS in recent releases, notably the intelligent personal assistant Siri, which was introduced in version 10.12 of macOS. In 2018 Apple announced that it had developed an API, reportedly codenamed Marzipan, to port iOS apps to macOS: macOS Mojave ported four first-party apps including Home and News from iOS, and it was announced that the system would be available for third-party developers to use from 2019.
