Aina smart ring for AI agent control

Aina has opened preorders for a $399 smart ring aimed at people managing AI agents throughout the day. The ring includes a mic, speaker, a small OLED screen, and a joystick, and ships in January 2027, with pricing rising to $499 after the early-bird period. The screen displays the next three predicted AI agent actions, each dismissible with a thumb flick. It integrates with Mac apps, recognizing the foreground application to surface context-relevant actions, including Approve, Reject, New Chat, and Check Limits when Claude is open. Users can also initiate agent tasks hands-free by holding a button and speaking. The ring supports additional functions including voice notes, remote control of music, Mac, and TV, and phone calls.
