The feature will be available on iPhones starting this afternoon, with Google planning to enable Assistant for Google Maps via an update that's rolling out "shortly."
On iOS and Android devices, Google Assistant will allow Google Maps users to control their navigation, reply to texts, and control music. On Android, it is also able to send messages through various messaging apps, a feature not available on iOS.
It can also do things like calculate your ETA so you can let friends and family know when you're set to arrive.
Google Assistant is already available on iOS devices through the dedicated Google Assistant app, but adding it into Maps makes it more readily accessible for the millions of people who already use the Google Maps app.
