Natura, an AI and hardware startup, is introducing Interface, a $99 smart ring that lets users interact with AI agents through simple voice commands. A press of the finger can capture an idea, start a task, or ask an AI assistant to do something, all without picking up a phone. The ring also tracks health data, including heart rate, heart rate variability (HRV), sleep, and daily activity.
Natura was founded by Carlo Edoardo Ferraris, who previously launched the tech accessories company Rolling Square. After years of developing consumer hardware, Ferraris came to believe that AI needed a more natural way for people to interact with technology. Rather than opening apps and typing commands, users should be able to ask an AI agent for help as they would ask another person, reports TechCrunch.
Interface is designed around that idea. At launch, it will work with several AI services and applications, including Meta’s Muse, Instinct, Grok Bot, Claude, and ChatGPT. Preorders are expected to open next month, with deliveries planned for December or January.
Why Put AI in a Ring?
Interface is not Natura’s first product. The company previously developed HumanPods, AI-enabled earbuds that let users communicate with AI agents. However, Ferraris said the rapid progress in voice technology led the company to reconsider which device would make AI easiest to access throughout the day.
In an interview with TechCrunch, he explained that people should be able to reach their AI agents at almost any time. A ring makes that possible because users can wear it while sleeping, showering, exercising, or going about their daily routines without needing to take it off.
The company sees plenty of potential uses. Someone going for a run could ask the ring to track a workout. In the morning, they could check their schedule. If they run out of shampoo, they could request a reorder, while someone watching TV before bed could ask the ring to switch it off and set an alarm.
The device could also help with work. After recording a meeting, for example, a user could ask an AI agent to prepare the notes and send them to a colleague.
AI responses can be delivered through connected headphones, an iPhone Live Activity, or Natura’s NatureOS app. Users who work with several AI tools can also choose which agent handles each request. They might use Claude for coding, Instinct to make a reservation, and another agent for a different task.
Controlling Computers Through Voice
Natura’s plans go beyond everyday requests. Ferraris believes AI agents will eventually handle much of the work people now do on computers. Tasks such as filling out forms, sending messages, locating files, and preparing presentations could be completed through voice instructions rather than navigating multiple applications.

He expects early adopters to be people who already use personal AI agents, particularly those working in technology. As these tools become more common, however, he believes the ring could appeal to a much wider audience.
The company’s longer-term vision is to make Interface a primary way of interacting with digital services, although that shift will depend on how quickly people adopt personal AI agents and how well the technology performs in everyday situations.
Price, Subscription, and Battery Life
Natura plans to launch Interface at $99 to encourage adoption, even though its manufacturing costs are comparable to those of established products such as the Oura Ring and Samsung Galaxy Ring. The company says the devices share many of the same components.
The introductory price will not necessarily last. After an initial free period of three to six months, Natura plans to charge users $9 per month. The company eventually intends to raise the hardware price as well, though it has not specified when that will happen.
Beyond AI functions, Interface measures heart rate, resting heart rate, HRV, sleep stages, daily movement, step count, and changes in skin temperature over time.
Natura estimates that the ring will last between six and 12 days on a full charge, depending on usage. A complete recharge takes around 100 minutes.
Competing in Two Smart-Ring Markets
Smart rings have largely developed along two paths. Companies such as Oura, Ultrahuman, and RingConn focus mainly on health tracking, while newer products from companies including Pebble and Vocci explore AI-based interactions.
Natura wants Interface to bring these functions together in one device. Ferraris says the challenge has been combining health sensors, voice communication with AI agents, meeting recording, and memory features without making the ring bulky or sacrificing battery life.
Whether users will want to wear a ring to manage both their health and AI assistants remains to be seen. But Natura is betting that a device that stays on the finger throughout the day could make AI more accessible than one that requires users to keep reaching for their phones.
