Natura’s $99 Smart Ring Lets AI Agents Live on Your Finger

A new AI-powered wearable called the Interface smart ring is launching at $99, aiming to bring voice-driven AI agents closer than ever—literally on your finger. Created by the hardware startup Natura, the ring integrates agent-style tasks with health tracking in a compact ring form designed for constant wear. It tracks metrics like heart rate, heart rate variability, sleep stages, activity, and skin temperature—all while enabling instant commands to your AI agents.

What It Can Do

The Interface ring lets users interact with AI agents through voice without pulling out a phone. Tasks like ordering items, managing schedules, recording meetings, or controlling devices can all be initiated with a press of the finger. Users will be able to choose which agent (such as ChatGPT, Claude, Muse, Grokbot, or Instinct) handles each task. Responses can come through connected headphones, iPhone live activity, or Natura’s companion app. The ring also allows for integrations with everyday devices like TVs, enabling voice commands to power them off or adjust settings.

Product Specs and Market Strategy

Natura reports that the ring delivers health metrics including resting and active heart rate, heart-rate variability, sleep tracking, movement, and skin temperature. Battery life is rated between six and twelve days depending on usage, and a full charge takes about 100 minutes. Though the initial price is $99, Natura intends to raise the cost after early rollout. It will also require a subscription fee of $9/month following a three- to six-month free trial period.

Hardware-wise, the ring comes from Natura’s previous experience building AI-enabled earbuds called HumanPods. Founders believe that recent progress in voice AI demands a more intimate and always-on interface. Naturals co-founder Carlo Edoardo Ferraris says the form factor of a ring enables true 24/7 access—including while showering or sleeping.

How It Stacks Up

The smart ring sector has so far been dominated by health-focused devices from companies like Oura, Ultrahuman, and RingConn. Natura distinguishes Interface by aiming to merge high-fidelity biometric tracking with robust AI agent access and external memory features. The company estimates its manufacturing costs are in the same ballpark as those of Oura and Samsung’s smart rings. The lower introductory price is intended to lower the barrier to entry and grow adoption before transitioning to a higher price point.

Pre-orders open next month, with shipping expected around December or January.

This represents a shift toward wearable devices serving not just as health trackers but as portals to AI agents—interfaces that aim to reduce screen time and streamline daily tasks. What matters now is whether the ring delivers on seamless interactions, battery life, and convincing utility in everyday settings. Keep an eye on how software compatibility, voice recognition accuracy, and privacy protections are handled once users begin testing the device in full.
