Natura introduces Interface, a $99 smart ring enabling users to control AI agents by touch while monitoring health metrics. The device supports multiple AI services and aims to be an always-worn personal assistant.

AI and hardware startup Natura has unveiled Interface, a smart ring priced at $99 that integrates access to various AI agents with health tracking capabilities. The ring allows users to summon AI assistants by pressing a finger to perform tasks, capture thoughts, manage schedules, and control connected devices — all without pulling out a phone. Concurrently, the device monitors vital health metrics such as heart rate, heart rate variability, sleep stages, physical activity, and skin temperature.

Founded by Carlo Edoardo Ferraris, who previously created the tech accessories company Rolling Square, Natura designed Interface to offer a seamless, natural interaction with AI agents at any moment. Ferraris emphasized the importance of having agents available 24/7, noting that the ring form factor is ideal because it can be worn constantly—even during showers or sleep.

Interface integrates with leading AI assistants including Meta’s Muse, Instinct, Grok Bot, Claude, and ChatGPT. Users can specify which agent handles particular tasks, allowing workflows such as coding with Claude, booking reservations via Instinct, or other activities with Grok Bot. Responses from agents can be delivered through connected headphones, an iPhone Live Activity, or Natura’s dedicated app, NatureOS.

Natura envisions the ring ultimately replacing many computer-based tasks, enabling users to execute actions like filling forms, messaging, file searches, and presentation drafting through intuitive voice commands directed at AI. This reflects a broader trend toward AI agents becoming central personal assistants. Initially targeted at tech-savvy users who already operate AI agents, the company believes widespread adoption will arrive within roughly a year.

The Interface ring is designed with a battery life ranging from six to twelve days and recharges in approximately 100 minutes. Manufacturing leverages components similar to those in competing health-focused smart rings such as Oura and Samsung Galaxy Ring, but Natura aims to attract users with a lower introductory price before increasing the cost. After a free trial period of three to six months, customers will be charged a $9 monthly subscription to access full AI agent features.

Prior products from Natura include HumanPods AI earbuds, but Interface represents a new form tailored for the latest voice AI technology. The company differentiates the ring by combining advanced health tracking with continuous AI agent access in a compact device with strong battery performance.

Natura plans to begin preorders in November 2026, with shipments expected starting December or January. By putting advanced AI assistance on users’ fingers, Natura seeks to redefine personal computing and smart device interaction through this novel wearable.
