Interesting trick: a ring with a screen for the actions of AI agents Aina has opened pre-orders for a ring with an OLED screen and thumb control. They suggest using it for short actions that usually require you to take out your phone. For example, before a meeting, the ring may offer to open it on a Mac, and the user approves the action with a swipe. Aina calls these prompts Cues. The system learns the habits of the user's devices and displays one appropriate action on the screen. Approval is required for its completion. Voice mode lets you contact an agent or dictate a note. The device connects to the iPhone, and for Mac it claims to manage meetings and applications. Pre-orders start at $399, shipping in early 2027.
