Sandbar Unveils Stream — an AI-Powered Smart Ring for Productivity
Startup Sandbar has announced Stream — a minimalist smart ring that replaces health tracking with an onboard AI assistant. The device listens, talks, and helps organize daily tasks, redefining the concept of personal productivity wearables.
An AI assistant at your fingertip
Unlike traditional smart rings that focus on pulse, sleep, or fitness, Stream acts as a discreet conversational companion. Tiny directional microphones can pick up even a whisper, allowing users to dictate notes or send quick messages in public without drawing attention.
The ring’s built-in AI assistant can respond using the wearer’s own cloned voice thanks to Eleven Labs technology. This enables hands-free interaction — asking questions, scheduling reminders, or generating ideas — without pulling out a phone or laptop.
Design and functionality
Stream features a tactile activation button to prevent background listening — privacy is physical, not just software-based. Once pressed, the assistant wakes instantly to record or reply, then powers down. The ring also functions as a universal media controller for Spotify or Apple Music, operating even offline.
Battery life is described as “all-day,” though Sandbar hasn’t disclosed exact endurance metrics. The device connects to iOS at launch, with Android support in development.
Pricing and availability
Stream will ship in summer 2026, priced between $249 and $299 depending on color and finish. Unlike many AI gadgets, it doesn’t require a subscription — all essential functions are included out of the box.
The rise of AI wearables
The Stream ring highlights a new wave of human-centered AI hardware. Instead of being glued to screens, users interact through subtle gestures and voice cues. Analysts predict this class of devices could become as common as smartwatches by the late 2020s — merging digital assistance, privacy, and minimalism in one form factor.
