APPLE
Apple was the first to offer its personal assistant, introducing Siri for the iPhone in 2011, and has been working to improve it over the years.
Recently, Siri was upgraded to interact with non-Apple applications, so users can book a ride with Lyft or make payments using Square Cash.
Apple has also introduced a Home application that can connect with smart appliances and other devices, and is reportedly working on a standalone speaker similar to Amazon Echo and Google Home
