Natura wants $99 for a ring that activates AI agents with a press
The startup Natura has announced Interface, a smart ring designed to let users activate AI agents with a press of a finger – while also functioning as a health tracker.
Startup company Natura has announced Interface, a smart ring that will let users activate AI agents with a press of a finger – while also working as a health tracker. The ring costs $99 at launch, pre-orders are expected next month, and shipping is planned for December or January.
What was announced
Interface was developed by Natura, a startup working in AI and hardware, and was presented on October 8, 2026. The idea is simple: with a press of a finger, the user can ask an AI agent to complete a task, capture a thought, or get things done without pulling out their phone. But the AI isn't the whole story – the ring is also supposed to measure health data such as heart rate, HRV (heart rate variability), sleep, and activity.
What separates Interface from other rings on the market is not the sensors, but the purpose: it is designed as a hardware input for third-party AI agents, not primarily as a health device with an app alongside it.
How it works
The user presses the ring to activate an agent. Different tasks can be routed to different agents, and the responses can be delivered through three channels: connected headphones, a Live Activity on the iPhone, or Natura's own NatureOS app. In practice, this means the ring functions as a kind of physical shortcut – a trigger that sets the agents in motion, while the actual response comes back through devices the user is already wearing or carrying.
At launch, the ring will connect to a range of AI agents and apps, according to the company, including Meta's Muse, Instinct, Grokbot, Claude, and ChatGPT – "and more." How these integrations technically work was not detailed in the company's presentation.
The founder's rationale: the agent that is always at hand
The driving force behind the project is Carlo Edoardo Ferraris, founder of Natura, who previously founded the accessories company Rolling Square. In an interview with TechCrunch, he explained the idea behind the ring format:
"Over time, we developed an understanding that you really want access to your agents around the clock," Ferraris told TechCrunch. "You don't want a single hour of the day where you can't reach them. And the ring format is perfect for this, because at its core it's an extension of you. You can shower with it; you can sleep with it. You never take it off."
Ferraris also predicted that "more or less within a year," most people will have a personal agent. That is a founder's assessment, not a fact – but it points to the company's bet: that personal AI agents will become so integrated into daily life that they need a dedicated, always-on hardware input.
Pricing: cheap now, pay later
The business model is worth noting. The ring launches at $99, but Natura plans to raise the price later. The strategy, according to the company, is first to get the device into people's hands, build usage, and create demand – and then adjust the price. Once the ring itself is purchased, a subscription follows: after an initial free period of three to six months, Natura will charge $9 per month.
Natura also claims that the ring's production costs are comparable to products like the Oura Ring and Samsung Galaxy Ring, because they use many of the same components. That is the company's own assertion, with no supporting documentation provided. If true, it would mean the price differentiation against competitors largely comes down to margins and software – but that remains unverified.
What is, for now, only claims
Several of the most sales-oriented details come from Natura itself and have not been independently verified:
- Battery life: The company states six to twelve days depending on usage, with a full charge taking around 100 minutes. No independent testing is available.
- Health measurements: According to Natura, the ring measures heart rate, resting heart rate, HRV, sleep stages, movement, steps, and skin temperature. Accuracy has not been verified by a third party.
- The cost comparison with Oura and Samsung is, as noted, the company's own account.
- The integrations: The list of agents is open-ended ("and more"), and it is unclear how Muse, Instinct, Grokbot, Claude, and ChatGPT actually connect to the ring – via the app, a software platform, or third-party APIs.
What remains
The concrete pre-order date has not been specified – only "next month." Nor has the final higher price been announced.
The big unanswered question is whether a press on a ring is actually a better input for AI agents than the phone's own voice assistant or apps. Natura is betting the answer is yes, and that the form factor – always on the finger, around the clock – is what makes the difference. Whether the agents, the integrations, and the subscription model hold up in practice will only become clear when the ring starts shipping in December or January.
