The smartest pitch for a wearable in years might be the simplest one: never be more than a finger-press away from your AI agent. That’s the bet Natura is making with Interface, a $99 smart ring that lets you trigger AI agents by voice, hands-free, whether you’re in the shower, mid-run, or falling asleep on the couch. According to TechCrunch, the device connects to a range of agents at launch, including Claude, ChatGPT, Grok Bot, Meta’s Muse, and Instinct, giving users the ability to pick which agent handles which kind of task.
Natura was founded by Carlo Edoardo Ferraris, who previously built Rolling Square, a consumer tech accessories company. His argument is straightforward: AI agents are advancing fast enough that the phone, as a physical interface, is already becoming a bottleneck. You shouldn’t have to pull a screen out of your pocket to ask your AI to reorder shampoo or check your calendar. The ring is meant to close that gap.
Interface is not Natura’s first product. The company started with HumanPods, AI-enabled earbuds built around voice interaction. But Ferraris concluded that earbuds still require too much intentional use. A ring, by contrast, never comes off. You sleep with it, shower with it, work out with it. That 24/7 availability is the whole point.
The use cases Natura describes are deliberately mundane, which is actually the right instinct. Ask the ring to start tracking your run. Wake up and ask what’s on your schedule. Tell it to turn off the TV and set an alarm. Have it send meeting notes to a colleague. Responses come through connected headphones, an iPhone Live Activity, or the NatureOS app. Nothing about this requires a new mental model — it’s just voice commands with better hardware placement.
On the health tracking side, Interface monitors:
- Heart rate and resting heart rate
- Heart rate variability (HRV)
- Sleep stages
- Daily movement and step count
- Skin temperature trends over time
Battery life is rated at six to twelve days depending on usage, with a full recharge taking around 100 minutes. Those numbers are competitive with Oura Ring and Samsung Galaxy Ring, which is telling. Natura says its manufacturing costs are roughly comparable to those products because many of the components overlap. The lower $99 launch price is a deliberate adoption play, not a sign of corners being cut.
Pricing deserves attention here. After an initial three-to-six month free period, Natura plans to charge $9 per month for its subscription. The company also says it intends to raise the hardware price eventually, once usage builds. So early buyers are getting a real deal, but the business model is subscription-first, which is worth factoring in if you’re evaluating this long-term.
The smart ring market is already getting crowded. Oura dominates health tracking. Ultrahuman and RingConn are pushing hard in the same direction. On the AI-first side, smaller players like Pebble and Vocci are also competing for this space. Natura’s differentiator, at least on paper, is that Interface combines serious health tracking with agent communication, meeting recording, and what Ferraris calls “external memory” — all in a notably small form factor with long battery life. That combination, if the hardware delivers, is a real gap to fill.
Preorders are expected to open next month, with shipping planned for December or January. Ferraris is candid that the first wave of buyers will be people already running personal AI agents, which right now means mostly people in tech. But his projection is that within a year, personal agents will be common enough that the audience widens significantly. If that’s right, getting a capable AI ring into people’s hands at $99 before that wave hits is a smart opening move.
