We knew this was only a matter of time, but Google today confirmed that Google Lens as part of the Google Assistant is now rolling out to all Pixel phone owners. That’s something Google already announced at its hardware event, but until now, the timing was unclear.

If you don’t see it when you call up the Google Assistant, though, don’t worry. The company says that this feature is rolling out slowly but that it’s coming to all Pixel phones in the U.S., U.K., Australia, Canada, India and Singapore over the “coming weeks.” Once the feature is live, you will see the Google Lens logo in the bottom right corner of the Assistant screen.
