Natura Unveils Interface, a $99 Smart Ring Built for Multi-Agent AI Control
Hardware startup Natura has announced Interface, a $99 smart ring pairing biometric tracking with access to AI agents like Claude, ChatGPT, and Grokbot.
Hardware startup Natura has unveiled Interface, a new wearable priced at $99 that connects wearers directly to autonomous AI agents. Founded by Carlo Edoardo Ferraris, previously behind consumer accessories brand Rolling Square, the company aims to move daily digital interactions away from mobile screens and into ambient voice controls.
Activated by pressing a finger against the ring, Interface allows users to capture fleeting notes, trigger external software workflows, and query assistants without handling a smartphone. Beyond ambient intelligence, the device functions as a standard biometric tracker, monitoring heart rate, resting heart rate, heart rate variability (HRV), skin temperature over time, sleep stages, and movement or step counts.
Continuous Access and Hardware Design
Interface marks a pivot from Natura’s initial hardware project, HumanPods, which used an earbud form factor to provide access to conversational agents. According to Ferraris, the transition to a finger-worn accessory reflects the requirement for uninterrupted, around-the-clock availability. Because the ring can be worn while sleeping or showering, it eliminates the downtime associated with devices that users regularly remove.
Despite using manufacturing components comparable to those found in market alternatives like the Samsung Galaxy Ring or Oura Ring, Natura is pricing Interface at an introductory $99 to encourage adoption before eventually increasing the cost. The device offers a battery lifespan estimated between 6 to 12 days depending on user activity, with a full recharge cycle taking roughly 100 minutes. After an introductory free period spanning three to six months, maintaining access will require a $9 monthly software subscription.
Agent outputs and system feedback are routed through connected earbuds, an iPhone Live Activity alert, or the company's companion NatureOS application. Pre-orders are set to launch next month, with the first wave of customer shipments scheduled between December and January.
Multi-Model Support and Desktop Automation
Rather than locking users into a single proprietary assistant, Interface connects across diverse platforms at launch. Supported tools and agents include ChatGPT, Claude, Grokbot, Instinct, and Meta's Muse. Wearers can delegate tasks dynamically based on model strengths—such as directing Claude to generate software code, assigning travel or dinner bookings to Instinct, or routing casual tasks to other bots.
Ferraris envisions the ring as a bridge toward automating conventional desktop tasks. In addition to issuing smart-home commands—like powering off a television or setting morning alarms—users can capture meeting audio and automatically prompt an assistant to dispatch transcripts to team members. Ferraris projects that agent-mediated workflows will steadily replace manual input mechanisms, handling document drafting, form completion, and file discovery via simple voice instructions.
What it means for developers
Interface reflects an ongoing shift in how end users interact with large language models, moving past traditional chat interfaces into ambient, always-on hardware endpoints. For developers building agentic workflows, hardware form factors like smart rings introduce new considerations:
- Multi-model routing: Users expect seamless transitions between different models based on contextual needs. Developers building services that need quick experimentation with multiple engines can access top AI models like Claude, GPT, Grok, and Gemini affordably through a unified API endpoint at https://apixoai.online.
- Low-latency inputs and multimodal outputs: Because input on the ring relies on quick voice commands and feedback must route to earbuds or lightweight mobile notifications (like iOS Live Activities), agent backends must optimize for sub-second execution and concise structured outputs.
- Screenless task delegation: As voice-first form factors take on scheduling, meeting summaries, and local computer actions, developers must prioritize reliable function-calling and tool integrations that execute safely without requiring manual screen confirmation.
