Siri is a virtual assistant with a voice-controlled natural language interface that uses sequential inference and contextual awareness to help perform personal tasks for iOS users. Spun out of the DARPA-funded CALO project, Siri was initially developed by Dag Kittlaus and his team of SRI International as an iPhone app. Apple bought Siri in 2010. In October of 2011 Apple re-released it as part of iOS 5. Siri is currently run by Bill Stasior, vice president, Siri, and the technology is integrated into the iPhone, iPod touch, and iPad, and into Apple’s new HomeKit home automation framework.
Cortana is your digital agent. She’ll help you get things done.

To get started, type a question in the search box, or select the microphone and talk to Cortana. (Typing works for all types of PCs, but you need a mic to talk.)
If you’re not sure what to say, you’ll see suggestions on your lock screen, and in Cortana home when you select the search box on the taskbar.

Google Now is an intelligent personal assistant developed by Google. Google Now, including Now cards, voice search and commands, is available in the Google app forAndroid and iOS. Google Now uses a natural language user interface to answer questions, make recommendations, and perform actions by delegating requests to a set of web services. Along with answering user-initiated queries, Google Now pro-actively delivers to users information that it predicts (based on their search habits) they may want. It was first included in Android 4.1 (“Jelly Bean”), which launched on July 9, 2012, and was first supported on the Galaxy Nexus smartphone. The service became available for iOS on April 29, 2013, without most of its features. In 2014 Google added Now cards to the notification center in Chrome OS and in the Chrome browser, however the notification center was later removed entirely from the Chrome browser.
Since 2015, Google has gradually phased out reference to “Google Now” in the Google app, with remaining use of “Now” being largely removed in October 2016, including replacing “Now cards” with “feed”. At Google I/O 2016, Google showcased its new intelligent personal assistant Google Assistant, which is seen an evolution of Google Now. Unlike Google Now, however, Assistant can engage in two-way dialogue with the user.
