Natura’s $99 Interface Ring Brings AI Agents to Your Fingertip

Preface

Natura’s Interface is a smart ring designed to make AI agents easier to access throughout the day. Rather than opening a phone or computer, users can press the ring and speak a request, such as capturing an idea, checking a schedule, or asking an agent to complete a task. The device also tracks health and activity metrics, bringing AI interaction and wearable monitoring together in one piece of hardware. Natura was founded by Carlo Edoardo Ferraris, an experienced consumer hardware entrepreneur who sees voice-based AI as an opportunity to rethink how people interact with technology. The company’s proposed approach centers on a simple idea: technology should respond naturally, wherever users are. This article examines how Interface works, what it can do, how it fits into the smart-ring market, and the practical questions raised by its price, subscription plans, battery life, and ambitions for AI-powered computing.

Lazy bag

Interface is a $99 smart ring from Natura that lets users summon AI agents with a press and a spoken request. It is intended to connect with services including Meta’s Muse, Instinct, Grokbot, Claude, and ChatGPT, while also recording meetings and tracking health indicators such as heart rate, sleep, movement, and skin temperature. Natura says the ring can run for 6 to 12 days on a charge, with a full recharge taking 100 minutes. Pre-orders are expected to open next month, and shipping is planned for December or January. After an initial three- to six-month free period, the company plans to charge $9 per month. Its central proposition is to make AI agents accessible through a wearable designed to stay on the user’s hand.

Main Body

Natura’s Interface is a smart ring built around voice access to AI agents. The device is designed so that users can press it and make a request without first taking out a phone. That request might involve recording a thought, starting a workout, getting information, or asking an AI agent to perform a task. The ring also serves as a health tracker, recording measures such as heart rate, heart rate variability (HRV), sleep, and activity. Its distinguishing idea is therefore not AI alone or health tracking alone, but the combination of both functions in a wearable intended for constant access.

The company was founded by Carlo Edoardo Ferraris, who previously established technology accessories company Rolling Square. His experience building consumer hardware led him to consider whether the rapid development of AI would require a different kind of interface. In his view, people should be able to make requests in a natural way, much as they would ask another person, rather than navigating a series of screens and menus. Interface is Natura’s attempt to turn that concept into a physical product that can be worn through ordinary daily activities.

At launch, the ring is expected to connect with a range of AI agents and apps, including Meta’s Muse, Instinct, Grokbot, Claude, and ChatGPT. Natura says users who rely on more than one agent can choose which service should handle a given request. For example, someone could ask Claude to write code, Instinct to book a reservation, and Grokbot to handle another task. This approach positions the ring as a control point for different services rather than as a device tied to a single AI assistant.

The company’s plans build on an earlier product, HumanPods, a pair of AI-enabled earbuds designed to support interaction with AI agents. Natura subsequently concluded that newer voice technology called for a different form factor. Ferraris told TechCrunch that users may want access to their agents throughout the day, rather than having periods when they cannot reach them. A ring, he argued, can remain on the body during activities such as showering and sleeping, making it a practical way to keep an interface close at hand. The company’s design premise is that a wearable people rarely remove could offer more continuous access than a device they must take out or put on.

Natura describes a broad range of possible everyday uses. A runner could ask the ring to begin tracking a workout. In the morning, a user might ask what is on the day’s schedule. Someone who notices they are out of shampoo while showering could request a reorder, while a person getting sleepy in front of the television could ask the system to turn it off and set an alarm for the morning. After recording a meeting, a user could ask the ring to send notes to a coworker. These examples illustrate the intended interaction pattern: speak a request in the moment, then let the relevant agent or connected service carry it out.

Responses can be delivered through connected headphones, an iPhone Live Activity, or the NatureOS app. This gives the ring several ways to communicate results without requiring every interaction to happen through the ring itself. Natura also says that users can choose which AI agent should handle a particular task, a feature that may matter as people adopt multiple tools for different purposes. In practice, the usefulness of this arrangement will depend on how smoothly the ring connects with those agents and apps, and on whether users can make requests reliably in the situations where they want hands-free access.

Interface is also intended to control connected devices, including computers. Ferraris expects AI agents to take on a growing share of computer-based tasks. He imagines people eventually using spoken requests to handle activities that currently depend on screens, such as filling out forms, messaging in apps, locating files, and drafting presentations. This is a longer-term ambition, not a description of what the ring necessarily replaces at launch. Ferraris acknowledged that not everyone currently has a personal agent, while predicting that adoption will broaden. He expects the first users to be people who already use personal agents, many of them in technology, and believes that most people may have one within a year, more or less.

The launch price is $99. Natura says it plans to raise the price eventually, but initially wants to put the device into people’s hands, encourage use, and build demand. After a free period lasting three to six months, the company plans to charge a $9 monthly subscription fee. These terms mean that the initial purchase price is only part of the expected cost for users who continue with the service after the free period. Natura says manufacturing costs are comparable to those of products such as the Oura Ring and Samsung Galaxy Ring because they use many of the same components. Its lower initial price is intended to reduce the barrier to adoption.

The ring’s health features include heart rate, resting heart rate, heart rate variability, different sleep stages, daily movement, step count, and skin temperature over time. These measures place Interface alongside health-focused smart rings, although Natura presents health tracking as one part of a broader product. The company says a full charge can last 6 to 12 days, depending on usage, and that a complete recharge takes 100 minutes. Battery life is relevant to the device’s central purpose: if the ring is meant to remain available throughout the day and night, frequent charging could interrupt that continuity.

The smart-ring market includes health-oriented products from Oura, Ultrahuman, and RingConn, as well as AI-oriented offerings from Pebble and Vocci. Ferraris argues that Interface differs by bringing health tracking together with communication with AI agents, meeting recordings, and external memory. He also emphasizes battery life and the ring’s small size as important parts of the design. These are company claims about the product’s position and hardware; how the device compares in everyday use will depend on its performance, comfort, agent integrations, and reliability.

More broadly, Interface reflects a shift in how technology companies think about the interface between people and digital services. Smartphones made touchscreens central to everyday computing, but voice-based agents could make some interactions more direct. A wearable ring offers a way to initiate these interactions without holding a phone, while other devices—such as headphones or a phone screen—can deliver the response. Whether this model becomes widely useful will depend on the agents’ ability to understand requests, carry out actions safely and accurately, and work across services. Natura’s product is an early effort to explore that possibility through a compact device designed to be worn continuously.
