Natura

Interface is a $99 smart ring from Natura that acts as a dedicated input device for AI assistants, letting the wearer summon an agent with a finger press instead of unlocking a phone. It connects to multiple assistants including Claude, ChatGPT, Meta's Muse, Instinct, and Grokbot , and the ring also tracks heart rate, HRV, sleep and activity, with 6 to 12 days of battery and a 100-minute full charge . Pre-orders are open now at the early-adopter price, with shipping planned for January. The product is aimed at people who already lean on chat-based agents during the day and want a faster path to them, whether for capturing a thought, recording a meeting, running a task, or controlling a connected device. Natura is positioning Interface between health-focused rings and AI-focused wearables , undercutting the price of competitors like Oura and Samsung's Galaxy Ring while adding agent routing as the headline feature. The timing matters because the current wave of consumer AI hardware is still searching for a form factor that users will actually wear all day, and a ring is one of the few options that stays on through sleep and showers. Natura was founded by Carlo Edoardo Ferraris, who previously founded Rolling Square, a company that makes tech accessories, and whose startup's first product was HumanPods, headphones designed for interacting with AI . Interface is the company's second swing at a dedicated agent-era device, this time trading audio for a tactile, always-on wearable that doubles as a health tracker.
