Natura unveils Interface smart ring for AI agent interaction

Wearable technology startup Natura has announced Interface, a $99 smart ring designed to provide a screenless interface for interacting with multiple AI agents. Operating on the NatureOS platform, the device allows users to execute tasks—such as scheduling, coding, or note-taking—through a “hold, speak, release” voice command system without needing to open individual smartphone applications.

The ring supports a wide range of AI services, including Claude, ChatGPT, and Meta’s Muse, with the NatureOS store offering over 140 agent options. Beyond AI integration, the stainless steel device includes health tracking capabilities for monitoring heart rate, HRV, sleep stages, and skin temperature. It also features a built-in microphone for voice commands and meeting recordings, with a physical indicator light to signal active recording.

Natura plans to offer the device with an initial early-access price of $99, potentially followed by a $9 monthly subscription service. The ring is expected to provide 6 to 12 days of battery life on a single charge, with a charging case capable of providing 10 full recharges. Shipping is anticipated to begin between late 2026 and early 2027.
