Slowly but surely, Amazon’s been turning its Fire tablets into Echos. It started with push to talk Alexa function. Last year, the company added a hands-free mode for the voice assistant. Now, it’s adding Show Mode, which brings the same title card UI you get on the company’s screen-enabled smart speaker.

Better still, Amazon’s introducing a Show Mode Charging Dock, a stand that effectively transforms the Fire into a makeshift Show. Place the tablet into a dock and it starts charging and automatically flips into Show mode, so you can do all of the standard Echo activities from across the room.
