Aina Opens Pre-Orders for a $399 Smart Ring to Control AI Agents

A thumb‑flick approval interface for proactive agent prompts, the ring will begin shipping in January 2027.

Overview

  • Aina announced pre-orders on Thursday, November 5, with a limited early‑bird price of $399 and a planned retail price of $499 when shipments start in January 2027.
  • The ring packs a color OLED, a five‑way joystick called the Shifter, a microphone, a tiny speaker, haptics and a titanium body, and the company claims a weight under 13 grams and up to 18 hours of battery life.
  • Its core feature set centers on ‘Aina Cues,’ a context‑aware operating system that surfaces yes/no prompts from connected AI agents and apps so users can approve or reject actions without taking out their phones.
  • At launch the device is focused on iOS and Mac, relies on third‑party integrations with agents and apps such as Muse, Instinct, Wispr Flow, Uber and Spotify, and its real‑world value hinges on the breadth and reliability of those connections.
  • The ring grew from Aina’s CES concepts and the Dune keypad, the startup raised $5.5 million in July and ran limited pilots in October, but broader developer support and scale will determine whether the premium gadget finds lasting daily use.
