Natura unveils a $99 smart ring for AI agents

Interface combines AI-agent controls with health tracking, and Natura plans to add a $9 monthly subscription after a free trial period.

Natura, the AI and hardware startup founded by former Rolling Square creator Carlo Edoardo Ferraris, has introduced Interface, a $99 smart ring built around AI agents. The device is designed to let people trigger tasks, capture thoughts, and interact with AI without constantly reaching for a phone. It also tracks health metrics, putting it in direct conversation with a crowded smart ring market. The bigger question is whether that mix of convenience and always-on AI will be enough to justify another connected device — and a subscription that comes later.

Interface is designed as a voice-first control for AI agents

Interface is meant to offer a different way to access AI agents. With a press of a finger, users can ask an agent to do something for them instead of opening an app or typing on a screen.

Ferraris said the idea came from a belief that AI now needs a different kind of interface, one that feels more natural than a phone keyboard or a traditional app. Natura’s goal is to help people look up from their screens while still getting everyday tasks done quickly.

At launch, the ring is planned to work with a number of AI agents and apps, including Meta’s Muse, Instinct, Grokbot, Claude, ChatGPT, and others. According to IT-PUB News, users who rely on more than one assistant will be able to choose which one handles a specific request.

That means one agent could be used for coding, another for booking a reservation, and another for a different task. Natura is positioning the ring as a control point for that growing ecosystem rather than as a standalone assistant.

Health tracking sits alongside the AI pitch

AI is the main selling point, but Interface is also a health tracker. Natura says it monitors heart rate, resting heart rate, heart rate variability, sleep stages, daily movement, step count, and skin temperature over time.

That puts the ring into a wearable market where health data is already a core feature. Natura argues its product stands out because it combines health tracking with the ability to communicate with AI agents and record meetings.

The company says the ring can also handle more routine tasks. A user could start workout tracking during a run, check their schedule after waking up, reorder shampoo while in the shower, turn off a TV and set an alarm before sleep, or send meeting notes to a coworker after a recording.

Responses from agents can be delivered through connected headphones, an iPhone Live Activity, or the NatureOS app.

Natura is betting people want constant access to agents

Ferraris said the company believes people will want access to their agents all the time, not just when sitting in front of a computer. He described the ring as a form factor that can stay on the body continuously, including during sleep or in the shower.

That idea sits at the center of Natura’s pitch. The company sees the ring as an extension of the user, built for a future in which many digital tasks are handled through voice requests to AI agents.

Ferraris also said he expects many tasks now done on computers to shift to agents over time. In his view, that could include filling out forms, messaging in apps, finding files, and drafting presentations.

For now, Natura acknowledges that the product will mainly appeal to people who already use personal agents, especially those in tech. Ferraris said the company expects broader adoption later, as more people get their own agents.

Natura starts at $99 before adding a subscription

Interface will launch at $99, but Natura does not plan to keep that price forever. The company says it wants to get the device into people’s hands first, build usage, and create demand before raising the price later.

Pre-orders are expected to open next month, with shipping planned for December or January.

There is also a recurring cost. After an initial free period of three to six months, Natura plans to charge a $9 monthly subscription fee.

The company says the ring’s manufacturing costs are similar to those of products such as the Oura Ring and Samsung Galaxy Ring because they use many of the same components. Even so, Natura is starting with a lower price to reduce the barrier to entry and encourage adoption.

A crowded smart ring market gets a hybrid newcomer

The smart ring market already includes health-focused devices from companies such as Oura, Ultrahuman, and RingConn, as well as AI-focused products from Pebble and Vocci. Natura argues that Interface is different because it tries to merge both approaches.

The company also points to battery life as a key advantage. Natura says the ring can last 6 to 12 days on a full charge, depending on usage, and needs 100 minutes to recharge fully.

That combination — long battery life, small size, health tracking, and AI-agent control — is central to Natura’s case that Interface belongs to a new category. Whether buyers see it that way may come down to something simpler: how useful the ring feels in daily life, and whether people are willing to pay for both the hardware and the monthly fee.

For now, Interface reflects a broader push in consumer tech to make AI less tied to screens and more present in everyday routines. Natura’s bet is that, for some users at least, that interaction could start with a ring rather than a phone or laptop.
