Introducing Interface, a $99 smart ring from the AI and hardware company Natura, built specifically for the age of AI agents. A simple press of your finger lets you instruct an AI agent to handle a task, jot down thoughts, and accomplish things without pulling out your phone. While AI sits at the core of Interface, the ring also functions as a health tracker, keeping tabs on metrics such as heart rate, HRV, sleep, and activity.

The company was founded by Carlo Edoardo Ferraris, who previously started the tech accessories brand Rolling Square. After years of creating consumer hardware, he grew convinced that fast-advancing AI required a fresh kind of interface — one that lets people request what they want in the same way they'd ask another person. The goal behind Interface is to help people lift their gaze from their phones while completing everyday tasks more quickly and naturally. At launch, the ring will work with a variety of AI agents and apps, including Meta's Muse, Instinct, Grokbot, Claude, ChatGPT, and others. Pre-orders are set to open next month, with shipping planned for December or January.

The smart ring wasn't the company's first product. That distinction belongs to HumanPods, a pair of AI-enabled earbuds built to let users interact with AI agents. But Natura felt it needed a new form factor tailored to the latest breakthroughs in voice technology. "You don't want to have even one hour of your day where you cannot access them. And the form factor of the ring is perfect for this because it's basically an extension of you. You can go shower with it; you can sleep with it. You never take it off."

According to the company, the use cases are limitless. If you're out for a run, you could ask the ring to begin tracking your workout. When you wake up, you could ask what's on your schedule for the day. If you're in the shower and realize you're out of shampoo, you could ask the ring to reorder it. If you're dozing off while watching TV, you could tell it to switch off the TV and set an alarm for the morning. After using it to record a meeting, you could ask it to send your notes from the discussion to a coworker. Responses from agents can come through connected headphones, an iPhone Live Activity, or the NatureOS app. What's more, users who depend on multiple AI agents and apps can choose which one handles a particular task. For instance, they could ask Claude to write code, Instinct to book a reservation, and Grokbot to take care of something else.

Beyond controlling AI agents, users can also control their devices, computers included. Ferraris says he believes that, in the end, most of what people do on their computers will be handled through AI agents. He envisions the ring eventually replacing many tasks that currently demand screens — from filling out forms and messaging in apps to locating files and drafting presentations — with straightforward voice requests to an AI agent. "Ultimately, the main interface between users and technology is going to be the ring," Ferraris said. "So it's not going to be immediate because even today, not everybody has a personal agent, but I think everybody is bound to have one. So in this first phase, we expect it's going to be for the people that already have a personal agent, which is mostly people in tech. But eventually, I think within a year, more or less, most people will have a personal agent."

Even though the ring will debut at $99, Natura intends to raise the price down the road. For now, the company wants to get the device into people's hands, build usage, and generate demand before doing so. Following an initial three- to six-month free period, Natura plans to charge a $9 monthly subscription fee. The company says the ring's manufacturing costs are comparable to those of products like the Oura Ring and Samsung Galaxy Ring because they rely on many of the same components. Still, Natura plans to price its ring lower at first to lower the barrier to entry and encourage adoption.

On the health tracking side, the ring monitors heart rate, resting heart rate, heart rate variability, different sleep stages, daily movement and step count, and skin temperature over time. The company says the ring can last 6 to 12 days on a full charge, depending on usage, and takes 100 minutes to fully recharge. While the smart ring market is crowded with health-focused offerings from companies like Oura, Ultrahuman, and RingConn, along with AI-focused ones from companies like Pebble and Vocci, Ferraris believes Interface distinguishes itself by merging both worlds. "This ring that we're about to launch is significantly different compared to any other ring out there today because we were able to combine not only the highest quality health tracking with the rest of the components that allow for agent communication and meeting recordings and external memory, but we were also able to do that with an incredibly long battery life, which is vital for a product like this, and in a size that is very, very small. The product itself is, from a hardware perspective, very different from anything else that's out there."
