AI hardware startup Natura has unveiled Interface, a $99 smart ring built around a press-to-talk button that triggers AI agents on demand. Users pick which agent handles each task — Claude for code, for example, or Instinct for reservations — across more than 140 supported agents and apps, including ChatGPT, Grok, Meta's Muse and Instinct.
Requests run through Natura's NatureOS voice layer, and the ring doubles as a health tracker, measuring heart rate, heart-rate variability, sleep and activity.
Interface is the company's second product after the HumanPods AI earbuds. It was founded by Carlo Edoardo Ferraris, formerly of accessory maker Rolling Square.
Preorders open next month, with shipments expected in December or January. An agent subscription is expected to kick in after a free introductory period, a pricing model to watch as AI wearables race to prove they can make money beyond the hardware sale.
