Natura's $99 Interface Ring Controls AI Agents

Natura, an AI and hardware startup, has launched Interface, a $99 smart ring designed to let users control AI agents with a press of a finger. Founded by Carlo Edoardo Ferraris, the ring connects with agents including Claude, ChatGPT, and Grok Bot, delivering responses via headphones, iPhone Live Activity, or the NatureOS app. It also tracks health metrics like heart rate, HRV, sleep, and skin temperature, lasting six to twelve days per charge. Preorders open next month, with shipping in December or January. A $9 monthly subscription follows an initial free period.
