AI companies are racing to build better agents, but Natura is betting that the next advantage lies in making those agents easier to summon without a screen.
The company has unveiled Interface, a smart ring designed to let users access multiple AI agents through a physical button rather than opening separate apps. Natura’s NatureOS software connects the ring to those agents and lets users control which applications they can access.
With a currently advertised price of $99, Interface represents a different approach to the AI race. Instead of building another foundational model, Natura wants to make existing AI services easier to use throughout the day. Whether that approach proves more convenient than a smartphone remains to be seen.
One ring, multiple AI agents
TechRepublic just covered how the agentic AI race is increasingly moving toward a future where users can access multiple AI agents through a single interface.
Natura’s Interface is one product tapping into that shift, allowing users to split tasks among different agents rather than rely on a single AI assistant. As of publishing, Natura has AI agents available, including Claude, Hermes, Grok Bot, Instinct, Meta Muse, and ChatGPT.
But Natura’s vision goes beyond putting multiple agents in one place.
Speaking to TechCrunch, founder Carlo Edoardo Ferraris described the product as “basically an extension of you,” arguing that its screen-free interaction makes it more intuitive.
The idea is to make AI assistance available without repeatedly opening apps or switching between services. Whether the ring delivers a smoother experience will depend on how reliably users can select agents, submit requests, and receive responses.
Doubles as a health-tracking device
Most smart accessories focus on one primary function, but Natura wants Interface to combine agentic AI with health tracking, bringing two distinct capabilities into one product.
The device is designed to track heart-related data, including heart rate, resting heart rate, and heart-rate variability (HRV). Because it is built to be worn constantly, it can track a user’s sleep stages, daily movement, step count, and even skin temperature over time. This gives users access to a range of health metrics alongside the AI agents available through Natura’s software.
Combining health tracking with AI agents could eventually allow users to ask questions about their activity or sleep trends. However, Natura has not confirmed that agents can access or interpret the ring’s health data.

What we know about Interface’s price, battery and compatibility
Natura has published a range of specifications for Interface, although details of some capabilities are still pending.
The company describes the device as a stainless-steel smart ring with a brushed silver finish, polished edges, a 7.35 mm band width, and U.S. sizes 7–13, designed to be worn on the index finger with its button facing the thumb.
For voice input, Interface has an integrated microphone and a press-to-talk control. Natura says the ring supports quiet speech when held close to the mouth, including whispering, as well as voice capture in loud environments such as a nightclub. A small recording indicator shows when recording is taking place, while haptic feedback provides physical feedback when attention is needed.
Regarding privacy, the company says the microphone stays off unless the user activates it with the dedicated button.
The ring is also advertised as waterproof for everyday use. However, Natura has not yet confirmed the final water-resistance rating.
Battery life is listed at an estimated six to 12 days per charge under typical daily use, with up to 13 hours of continuous recording. Natura estimates a full charge takes 100 minutes, while the charging case is expected to provide 10 full ring recharges.
The website currently directs prospective buyers to a waitlist and says Interface pairs with an iPhone or Mac. While its pricing is currently listed at $99, TechCrunch says it may change later, and the company also wants to offer a $9 monthly subscription.
What this means for users
Interface reflects a broader shift in how people may interact with AI, moving from opening individual apps to accessing multiple agents through a more immediate, everyday interface. If Natura delivers on that promise, users could find it easier to delegate small tasks throughout the day while keeping health-tracking data in the same product ecosystem.
But convenience alone will not determine whether the idea catches on. Users will need reliable agent responses, useful health measurements, and confidence in how their voice recordings and personal data are handled.
Until Natura’s remaining specifications are confirmed and the product is tested in real-world conditions, Interface is an interesting bet on how people might use AI, rather than proof that a new way of interacting with it has arrived.
