Natura, an AI and hardware startup, has launched Interface, a $99 smart ring designed to bring AI agents directly to users' fingertips. This innovative ring allows wearers to summon AI agents to complete tasks, capture thoughts, and control smart devices simply by pressing a finger, eliminating the need to pull out a phone. Besides its AI capabilities, the Interface also functions as a health tracker, monitoring vital signs such as heart rate, heart rate variability, sleep quality, and daily activity. Founded by Carlo Edoardo Ferraris, who previously established Rolling Square, Natura aims to create a seamless interface for interacting with AI that feels as natural as talking to a person.

At launch, the Interface ring will support a variety of AI agents and applications, including Meta’s Muse, Instinct, Grok Bot, Claude, and ChatGPT. Preorders are set to begin next month, with shipments expected between December 2026 and January 2027. Natura’s vision is to provide users with continuous 24/7 access to their AI agents through a wearable that users can barely notice — the ring form factor is designed to stay on through all daily activities, including sleeping and showering. This constant connection aims to enhance productivity by enabling people to manage routine tasks hands-free, whether tracking workouts during runs or sending meeting notes from recorded conversations.

Ferraris envisions the Interface ring as a future cornerstone of computing, potentially replacing tasks currently reliant on screens by leveraging AI’s capabilities through voice commands alone. Users will be able to assign specific duties to their preferred AI agents, handling everything from coding to booking reservations. The ring also allows for device control, including computers, signaling a shift towards AI-driven interactions and a more natural mode of technology use. Initially targeted at tech-savvy users who already employ personal AI assistants, Natura believes the device will become mainstream within a year as personal agents grow more widespread.

Natura plans to start with a $99 retail price for the Interface ring to encourage adoption, with a subsequent monthly subscription fee of $9 after an initial free trial period. The hardware is comparable in cost and complexity to competitors like the Oura Ring and Samsung Galaxy Ring but offers enhanced AI integration alongside health tracking and long battery life lasting six to twelve days. By combining high-quality health monitoring with innovative AI agent functionality in a compact design, Natura positions Interface as a unique product in the evolving smart ring market.
