A $99 ring that sends your AI agents to work

Smart rings have mostly been about sleep and heart rate. A startup called Natura wants one to be the button you press to put an AI agent to work. Here is what it announced, what it will cost, and what is still a promise.

What Natura announced

According to TechCrunch, Natura's ring is called Interface and costs $99 at launch. Natura was founded by Carlo Edoardo Ferraris, who previously started the accessories maker Rolling Square. Its earlier product was HumanPods, a pair of AI earbuds.

• Press to ask: you press a finger to the ring to give an AI agent a task or capture a thought.
• Choose your agent: at launch it works with Meta's Muse, Instinct, Grok Bot, Claude and ChatGPT, with more promised. You pick which agent handles which job.
• Hear the answer: replies come through connected headphones, an iPhone Live Activity, or Natura's own app.
• Control devices: the company says it can also control devices, including computers.
• Health tracking: heart rate, resting heart rate, heart rate variability, sleep stages, steps and activity, and skin temperature.

What it will cost

The $99 is only the start. TechCrunch reports Natura plans a $9 monthly subscription after a free period of three to six months, and expects to raise the ring's price after launch.

When you can get it

Natura expects to open preorders in November, with shipping in December or January. TechCrunch presents these as targets, not firm dates.

Company claims to treat with care

These come from Natura and have not been independently checked:

• The ring matches the best health trackers while also handling agents, meeting recording and an "external memory".
• Battery life of 6 to 12 days, and build costs comparable to the Oura Ring and Samsung Galaxy Ring.
• Most computer tasks will eventually be handled by agents through the ring, and most people will have a personal agent within about a year.

The report includes no hands-on test. It also doesn't cover health-tracking accuracy, privacy or how your data is handled.

Who it is for

TechCrunch notes the launch is aimed at people who already use a personal AI agent, which today mostly means people in tech. It lists Oura, Ultrahuman and RingConn as the health-ring competition, and Pebble and Vocci as rivals on the AI side.

A simple test before you preorder: list three tasks you would actually hand to an agent from your finger this week. If you can't name three, wait for reviews and for the final subscription price.
