Natura's $99 AI Ring Puts Agents on Your Finger
Natura wants to put an AI agent on your finger for $99. The startup's new product, called Interface, is a smart ring that lets users summon an AI agent with a press of the finger, whether that's to capture a thought, fire off a task, or get an answer without pulling out a phone. It also tracks heart rate, HRV, sleep, and activity, so it doubles as a fitness wearable while it handles agent requests.
The ring comes from Carlo Edoardo Ferraris, who previously founded the accessories company Rolling Square. After years building consumer hardware, Ferraris concluded that AI's rapid advances called for a new kind of interface, one where people could ask for things the way they'd ask another person, rather than typing or tapping through apps.
Interface isn't Natura's first attempt at this problem. The company's earlier product, HumanPods, were AI-enabled earbuds built for the same kind of voice interaction. Natura eventually decided earbuds weren't the right form factor and moved to a ring instead.
At launch, Interface will connect to agents including Meta's Muse, Instinct, Grokbot, Claude, and ChatGPT. Pre-orders open next month, with shipping set for December or January.
Meet Interface, a new $99 smart ring from AI and hardware startup Natura that’s designed for the era of AI agents. With a press of your finger, you can ask an AI agent to complete a task, capture thoughts, and get things done without reaching for your phone. And while AI is at the heart of Interface, the ring also doubles as a health tracker, as it monitors metrics like heart rate, HRV, sleep, and activity.
Why this matters
A $99 ring is a cheap bet on a big claim: that screens become optional once agents can act on our behalf. Ferraris is betting Interface becomes the input device for that shift, handling forms, messages, and file retrieval with a tap instead of a tap-tap-tap through apps. For founders building agent products, the interesting part isn't the health-tracking features, which are table stakes at this point for any wearable. It's the bet that physical, ambient interaction beats chat windows and app switching as the default way people call on AI.
We'd push back on the "ultimately most computer tasks go through agents" framing until Interface or something like it proves people actually trust a ring tap to draft a presentation correctly. Hardware is hard, agent reliability is harder, and combining both in one $99 device is a lot to ask of early adopters. Worth watching: whether Natura ships agent accuracy good enough that people stop reaching for their phones out of habit, not just capability.

Common Questions Answered
What is the primary function of Natura's Interface smart ring?
Interface is a $99 smart ring that allows users to summon an AI agent with a finger press to capture thoughts, complete tasks, or get answers without pulling out a phone. The ring is designed as an input device for the era of AI agents, enabling users to handle forms, messages, and file retrieval through ambient interaction rather than traditional app navigation.
What health tracking capabilities does the Interface ring offer?
Beyond its AI agent functionality, Interface doubles as a fitness wearable that monitors heart rate, HRV (heart rate variability), sleep patterns, and activity levels. These health-tracking features are considered standard capabilities for modern wearables in the current market.
Who founded Natura and what is their background in hardware?
Natura's Interface ring comes from Carlo Edoardo Ferraris, who previously founded Rollin, an accessories company. This background in hardware development positions Ferraris to create wearable devices that combine physical design with advanced technology.
What is Natura's core bet with the Interface ring's design philosophy?
Natura is betting that screens become optional once AI agents can act on users' behalf, and that physical, ambient interaction through a ring is more effective than traditional chat-based interfaces. The company believes Interface will become the primary input device for this shift away from screen-dependent interactions toward agent-driven task completion.
