Natura has launched Interface, a smart ring priced at $99 that allows users to command AI agents without touching a phone.
The device functions as a health tracker alongside its primary role as a command interface. It monitors heart rate, heart rate variability, sleep stages, daily movement, step count, and skin temperature.
The hardware
Carlo Edoardo Ferraris founded Natura after previously building consumer hardware with Rolling Square. He argued that the rapid progress in artificial intelligence required a new way for people to request tasks naturally.
The goal is to stop users from constantly looking down at their phones to complete everyday chores. At launch, Interface connects with various AI agents and apps, including Meta’s Muse, Instinct, Grokbot, Claude, and ChatGPT.
Pre-orders are scheduled to open next month, with shipping targeted for December or January.
This is not the company’s debut product. Natura previously released HumanPods, a pair of AI-enabled earbuds. Ferraris felt that voice technology had advanced enough to warrant a new form factor.
“Over time, we evolved to an understanding where you really want to have access to your agents 24/7,” Ferraris told TechCrunch. “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.”
Use cases
The company lists numerous scenarios for the device. A runner could ask the ring to start tracking a workout. Upon waking, a user could query the schedule for the day.
If a person is in the shower and realises they need more shampoo, they can request the ring to place a reorder. While watching television, a user can ask the device to turn off the screen and set a morning alarm.
After recording a meeting, the ring can send discussion notes to a colleague. Responses from agents appear through connected headphones, an iPhone Live Activity, or the NatureOS app.
Users managing multiple AI tools can specify which agent handles specific tasks. For instance, they might direct Claude to write code, Instinct to book a reservation, and Grokbot to manage other duties.
Controlling devices
Users can also control their computers through the ring. Ferraris believes most computer tasks will eventually be managed by AI agents. He expects the ring to replace screen-based interactions, such as filling out forms, messaging in apps, finding files, and drafting presentations, with simple voice requests.
“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.”
Cost and battery
Although the launch price is $99, Natura intends to raise it later. The company aims to secure initial adoption and build demand before increasing costs. After an initial three- to six-month free period, a $9 monthly subscription will begin.
Manufacturing costs are comparable to products like the Oura Ring and Samsung Galaxy Ring due to shared components. Natura keeps the initial price low to reduce the barrier to entry.
The ring lasts 6 to 12 days on a full charge, depending on usage, and requires 100 minutes to fully recharge.
Market position
While the market contains health-focused options from Oura, Ultrahuman, and RingConn, as well as AI-focused ones from Pebble and Vocci, Ferraris believes Interface combines both categories.
“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.”
