Natura unveiled Interface, a $99 smart ring that provides always‑on access to AI agents via voice, while also functioning as a health tracker monitoring heart rate, HRV, sleep, activity and skin temperature. The ring connects to multiple agents and apps (including Meta’s Muse, Instinct, Grokbot, Claude and ChatGPT), will offer 6–12 days of battery life, a 100‑minute full charge time, and is slated for preorder next month with shipping in December or January and a planned $9/month fee after a 3–6 month free period.
