Natura is introducing Interface today so you can use your smart ring to give commands to your personal AI Agents.
Interface is Natura’s smart ring for voice requests. Worn on the index finger and paired with a phone, it connects to personal AI agents through NatureOS, which enables you to use a variety of AI agents and their accompanying large language models (LLMs), said Carlo Ferraris, in an interview with GamesBeat.
The device costs $99 for early adopters and it will be shipping in January, 2027. It means that you can easily access your AI agents to perform tasks for you, wherever you are. You press a button on the ring, speak and then release it to send a request to your agent.
People can bring the agents they already use, such as Claude Code, Codex, Hermes, Instinct or Muse, or choose from more than 140 in the NatureOS store. They decide which apps and files each agent can reach on their Mac and iPhone, and NatureOS asks for approval before any action that needs it.
“Every era of computing got its interface. The mouse, then the touchscreen. We built Interface so people can reach their agents without reaching for a screen,” said Ferraris.
“We’ve been working on it for for quite some time, and we’ve been working on the concept of the Interface between humans and technology in this new phase of tech, for more than two years now,” Ferraris said. “It’s a problem we’ve been trying to solve for a long time. We think it’s quite the product for the era of tech that we’re about to enter, the agentic era.”
You can speak quietly to your ring and it will capture your message.
He added, “As I said, we’ve been working understanding what the next interface is going to be for a long time, and we saw AI is the turning point for technology, where the the technology itself first understands what the user wants to speak, without having to use buttons and interfaces, and then that was the moment of ChatGPT. We see a future where this is frictionless.”
What it does
- Ask any agent. Press and hold, speak, release. Agents can also use computer and phone on the user’s behalf, within the access the user grants.
- Capture a thought. Dictate a note while it is fresh, close to the ring, whispered or at normal volume.
- Keep a conversation. Double-click to start a longer recording, double-click to stop. Notes, decisions and next steps return in NatureOS.
- Replies find you. Hear the answer through headphones or HumanPods, follow it as a Live Activity on the iPhone lock screen, or open the result in NatureOS.
- Health sensing. Interface is designed to track heart rate, resting heart rate, heart-rate variability, sleep stages, steps and skin temperature. Sharing with agents is optional. Health features are in validation.
- Private by design. Interface records only when the button is used, and a light shows when it is on.
Hardware
The ring is made of stainless steel. It’s a 7.35 mm band, with U.S. sizes 7 to 13. It has a sealed, waterproof design for everyday wear. Battery life lasts up to 12 days depending on use; charging from empty takes about 100 minutes, and the charging case holds 10 full recharges.
Price and availability
Interface costs about as much to make as an Oura ring, which retails at about $350. For launch, Natura is covering the difference: early adopters pay $99, with a free plan or a $9/month subscription. Interface ships in January.
The waitlist opens today at natura.inc/interface, and Natura will show its place in line and share confirmed specifications and delivery timing before anyone orders. Natura will present Interface live in San Francisco on November 9.
How it works
Choose access, review actions that need approval and follow progress. Agents carry out the work on your Mac or through a remote service. Conversations and results stay within reach in NatureOS. Replies can return through connected headphones, an iPhone Live Activity or the app.
You can press and hold the button, speak, then release. Capture a thought, send an agent a task or record a conversation. Double-click to start and stop a longer recording. Ferraris believes the device has a lot less friction than other ways of communicating.
Natura comes from the team behind Rolling Square. Also from Natura: HumanPods, open-ear wireless earbuds, and tinyNature, Natura’s own AI companion.
Ferraris said the ring is designed as an always-available interface. The ring can store up to two hours of meeting audio without syncing to a phone, then provide transcription and summaries through connected agents. The ring can also control computers and connected devices, such as switching lights or using a computer to perform tasks.
The app is intended to connect with multiple agents rather than require a proprietary agent. It currently supports agents on iMessage, local agents running on a computer, and cloud agents connected through webhooks.
Rivals in the market include Limitless Pendant, Friend, Pebble Index and Sandbar, with products generally focused on transcription, companionship, or limited voice commands.
Natura differentiates the ring through rechargeable hardware, longer recording use, agent interoperability, and integrated health sensors comparable to Oura.
Origins
The company has about seven employees and was started roughly two years ago. It is backed by angel funding and capital from the founder’s hardware-accessories company, Rolling Square.
The company raised a small round of funding from angels in March. But it has been able to finance much of the cost through Rolling Square, a tech accessories company that has been around for a decade. Natura tried using AI with earbuds first, but then switched to the ring.
Ferraris said he likes to use Claude Code for work, programming various tasks. And he uses the Tiny Nature agent that the company made, and he’s testing a variety of agents now. He can get it to show things on his computer screen or turn the lights on.
“The whole philosophy of of Natura is we want to go back to a world where we don’t have to spend so much time operating technology, but we also don’t want to be like in the forest and go light a fire,” Ferraris said. “We want the advantage of of technology without having to babysit the technology and use it. We think there’s too much like addictive behavior created by technology. We have all the addictive behavior created by like excessive screen time, social media, and so on. For us, voice has always been at the center.”
