Natura’s $99 Interface Ring Wants to Be Your Remote Control for AI Agents

Natura, an AI and hardware startup, has a new answer to the question "how do I talk to my AI agent without taking out my phone?" It is a ring. The company calls it Interface. It costs $99 at launch and, per TechCrunch’s Aisha Malik, it sends your voice requests to agents such as Claude, ChatGPT and Grok Bot while it tracks your heart rate and sleep.

This post summarizes the announcement, prices the full cost of ownership, and lists the questions a buyer should ask before preordering. All product facts come from TechCrunch’s interview with the founder. We could not read a Natura product page for Interface at the time of writing, so details are the company’s statements as reported.

TL;DR: what Natura announced

What Interface does

Ferraris says the ring is built for "the era of AI agents." The use cases TechCrunch lists are everyday ones:

• Start tracking a workout while you run.
• Ask what is on your schedule when you wake up.
• Reorder shampoo from the shower.
• Turn off the TV and set an alarm as you fall asleep.
• Record a meeting, then ask the ring to send notes to a co-worker.

Responses can reach you through connected headphones, an iPhone Live Activity or the NatureOS app. Users who run several agents can choose which agent gets which task. TechCrunch’s example: ask Claude to write code, Instinct to book a reservation, and Grok Bot to handle something else.

The ring can also control devices, including computers. Ferraris told TechCrunch he thinks most tasks people do on computers will end up handled through AI agents, and that the ring could replace many screen tasks such as filling forms, messaging, finding files and drafting presentations with voice requests.

Who is Natura

Ferraris previously founded the tech accessories company Rolling Square. After building consumer hardware for years, he became convinced rapid AI progress needed a new kind of interface that lets people ask for what they want the way they would ask a person, per TechCrunch.

The ring is not Natura’s first product. TechCrunch says the first products were HumanPods, a pair of AI-enabled earbuds designed to let users interact with AI agents. Natura decided it needed a new form factor "built for the latest advances in voice technology," per the report. The company’s earlier software product was named NatureOS, and TechCrunch lists the NatureOS app as one of the response channels. Natura was also reported under the name Natura Umana when it showed HumanPods at CES 2025.

Ferraris explained the switch to a ring this way: "you really want to have access to your agents 24/7... the form factor of the ring is perfect for this because it’s basically an extension of you. You can go shower with it; you can sleep with it. You never take it off."

The price: $99 is not the whole price

The sticker is low. The real cost has three parts.

A rough first-year view, if the free period is six months: $99 plus six months at $9 is $153 before your own agent plans. If it is three months, nine months of fees is $81, so $180. These are our arithmetic on reported figures, not a quote from Natura.

Ferraris says manufacturing costs are comparable to Oura and Samsung Galaxy Ring products because they use many of the same components. Natura chose to price low at first "to reduce the barrier to entry and drive adoption." That is a common hardware strategy. It also means early buyers should expect price changes.

How it compares with other rings

TechCrunch notes the smart ring market is crowded with health-focused products from Oura, Ultrahuman and RingConn, and AI-focused ones from Pebble and Vocci. Natura argues Interface stands out by combining both groups.

Ferraris, quoted by TechCrunch: "This ring that we’re about to launch is significantly different compared to any other ring out there today because we were able to combine not only the highest quality health tracking with the rest of the components that allow for agent communication and meeting recordings and external memory, but we were also able to do that with an incredibly long battery life... and in a size that is very, very small."

Those are product claims. We have no independent test data on health accuracy, microphone quality in noise, or battery life under constant voice use. Treat the six-to-12-day battery range as unverified until reviewers test it.

Questions to ask before you preorder

The announcement leaves real gaps. Check these before you pay.

1. Privacy and recording. The ring records meetings and keeps "external memory." Where are the audio and transcripts stored? Who can access them? What do the agents it connects to receive? TechCrunch does not say. Recording a conversation can also be illegal without consent in some places. Read our post on Instinct and agent data retention for the kind of questions to ask any agent product.

2. Platform support. TechCrunch mentions an iPhone Live Activity and the NatureOS app. It does not state Android support. Ask.

3. Agent permissions. If the ring can control your computer and place orders, what can it do without confirmation? Voice requests are easy to mishear. A reorder command in the shower should not buy the wrong thing. Look for confirmation steps and spending limits. Our guide to the agent permission boundary pattern covers the idea in the coding setting.

4. What the $9 buys. Natura has not detailed in the report whether the fee covers cloud processing, speech recognition, memory, or access to partner agents.

5. Health claims. The ring tracks several vitals. Ask whether it has any regulatory clearance for health use. TechCrunch makes no such claim, and we found none.

6. Longevity. A subscription tied to a startup’s cloud means features can vanish if the company closes. Ask what the ring does offline.

Why this matters for people building agents

Interface is a bet on a specific idea: the screen is the bottleneck, and voice plus a wearable trigger removes it. Whether or not Natura wins, the pattern matters to agent builders.

• Agents are becoming back-end services with many front doors. Ring, earbud, watch, phone and glasses all become input devices. Your agent’s API and permission model matter more than its chat UI.
• Routing across agents is now a user feature. Natura lets people name which agent handles a task. Expect more products where the user, not a vendor, assigns work to Claude, Grok or ChatGPT.
• Audio-first design needs short, confirmable outputs. A ring has no screen. Responses arrive by headphones or a Live Activity. Design agent replies that fit a few seconds.
• Always-on devices raise consent questions. Our coverage of Apple’s AirPods camera leak and smart-glasses misuse and bans shows how fast social rules form around wearables.

For the wider hardware landscape, compare Natura’s approach with OpenAI’s reported AI companion smart speaker, the ChatGPT watch idea from Sam Altman, and the agents Natura names in our comparison of OpenAI Dots, Grok Bot and Meta Muse.

Practical takeaways

• Do not preorder on the $99 alone. Add the $9 per month fee and your own agent plans.
• Wait for independent reviews. Battery, microphone and health accuracy claims are all from the company.
• Treat voice-to-agent actions as high risk. Prefer products that confirm purchases and device commands.
• If you build agents, plan for wearable inputs. Short audio replies, clear confirmations and strict permissions are now product features.
• Watch the November preorder page. A real spec sheet, privacy policy and refund terms will answer most of the questions above.
