There are still people who are unaware that Siri doesn’t just limit to one’s iPhone. You can also ask help from Siri using your laptop–that is if you’re using a Macbook.
For Siri to appear on your desktop, click the icon on the dock. Siri will pop up in the upper-right corner of the screen. Similar to using your phone, Siri will ask this question: What can I help you with? Obviously, it is the cue for you to start asking her questions. Don’t forget to upgrade Siri for a better helping hand.
