Introducing Interface, a new $99 smart ring from AI and hardware startup Natura designed for the age of AI agents. With the press of your finger, you can ask an AI agent to complete a task, capture your thoughts, and get things done without ever reaching for your phone. And while AI is at the heart of the interface, the ring also doubles as a health tracker, as it monitors metrics like heart rate, HRV, sleep, and activity.
The startup was founded by Carlo Edoardo Ferraris, who previously founded technology accessories company Rolling Square. After years of building consumer hardware, he became convinced that rapidly advancing AI required a new kind of interface that allowed you to ask people what you wanted, just as you would ask people.
The idea behind Interface is to allow people to look up from their phones while performing everyday tasks more quickly and naturally. At launch, the ring will connect with a variety of AI agents and apps, including Meta’s Muse, Instinct, Grokbot, Claude, ChatGPT, and more.
Pre-orders will begin next month, with shipping expected in December or January.
The smart ring wasn’t the company’s first product. It was HumanPods, AI-enabled earbuds designed to allow users to interact with AI agents. However, Natura saw the need for a new form factor built for the latest advancements in voice technology.
“Over time, we’ve come to understand that customers really want to have 24/7 access to an agent,” Ferrari said in an interview with TechCrunch. “You don’t want to have even an hour of your day without access. The shape of the ring is perfect for this because it’s basically an extension of yourself. You can shower with it on, you can sleep with it on. You never take it off.”
According to the company, the use cases are endless. If you’re out for a run, you can ask Ring to start tracking your workout. When you wake up, you can ask for the schedule for the day. If you’re taking a shower and realize you’re out of shampoo, you can ask Ring to reorder it for you. If he falls asleep while watching TV, you can tell him to turn off the TV and set an alarm for the morning. After you use it to record a meeting, you can ask your colleagues to send your discussion notes.
Responses from agents can be delivered through connected headphones, iPhone Live Activity, or the NatureOS app.
Additionally, users who rely on multiple AI agents or apps can specify which agent or app handles a particular task. For example, you can ask Claude to write code, Instinct to make reservations, and Grokbot to do other tasks.
In addition to controlling AI agents, users can control devices, including computers. Ferrari said he believes most of the things humans do on computers will eventually be handled through AI agents. He sees Ring eventually replacing many tasks that currently require a screen with simple voice requests to an AI agent, from filling out forms and messaging in apps to finding files and drafting presentations.
“Ultimately, the primary interface between the user and the technology will be the Ring,” Ferrari said. “Even today, not everyone has a personal agent, so I think it’s not going to happen right away, but I think everyone will definitely have a personal agent. So I expect that in this first phase, it’s going to be people who already have a personal agent, primarily people in the technology industry. But ultimately, I think within a year, most people will have a personal agent, more or less.”
The ring will retail for $99, but Natura plans to increase the price eventually. For now, the company wants to get the device into people’s hands, build usage and create demand before that. After an initial 3-6 month free period, Natura plans to charge a $9 monthly subscription fee.
The company says the cost to manufacture the ring is comparable to products such as the Oura Ring and Samsung Galaxy Ring because it uses many of the same components. However, Natura plans to lower the price of the ring initially to reduce barriers to entry and encourage adoption.
When it comes to health tracking, the ring tracks heart rate, resting heart rate, heart rate variability, different sleep stages, daily movement and steps, and skin temperature over time.
The company says the ring will last six to 12 days on a full charge, depending on usage, and a full charge takes 100 minutes.
The smart ring market is filled with health-focused products from companies like Oura, Ultrahuman, and RingConn, and AI-focused products from companies like Pebble and Vocci, but Ferrari believes Interface stands out by combining both worlds.
“This ring that we are about to launch is very different compared to other rings on the market today because we were able to not only combine the highest quality health tracking with the remaining components that allow for agent communication, meeting recording, and external memory, but also in a very small size with the incredibly long battery life that is essential for this type of product. The product itself is very different from other products from a hardware perspective.”
