The tech giant hopes to expand Siri's capabilities well beyond Apple apps and searching the web. An example might be to allow the personal assistant to book a ride through a ride-hailing app listed in Apple's App Store.
Siri is a built-in intelligence assistant that's part of some Apple products. The program can help you schedule reminders or assist you in texting, but can also do fun things like tell you exactly what planes are flying above your location. With more recent Apple products you can go entirely hands-free by simply saying, "Hey, Siri."
