Google today announced it’s making it possible to use the voice command “Hey Google” to not just open but also perform specific tasks within Android apps. The feature will be rolled out to all Google Assistant-enabled Android phones, allowing users to launch apps with their voice as well as search inside apps or perform specific tasks — like ordering food, playing music, posting to social media, hailing a ride, and more.

For example, users could say something like, “Hey Google, search cozy blankets on Etsy,” “open Selena Gomez on Snapchat,” “start my run with Nike Run Club,” or “check news on Twitter.”
