Two former Meta employees are launching a new AI-powered smart ring. Stream Ring is the debut product from and it’s available to pre-order right now. Sandbar describes Stream as “your extended self,” which is to say that it’s a deliberately minimalist smart ring that you can use to take voice notes and interact with a chatbot directly using the built-in touch-activated microphone.

When you create a voice note, the Stream Ring uses haptic feedback to confirm that it’s been recorded. You hold the sensor to speak and tap it if you want to interrupt and start over. It can automatically transcribe your voice interactions, whether you’re simply compiling a grocery list on the go, asking it to fetch some information from the web, or having a more back-and-forth conversation with the device. These notes will appear in the Stream app via Bluetooth, which will be iOS-only at launch.

Sandbar thinks a ring is the best form for its wearable to take as it’s always available and accessible, whatever you’re doing, so you easily can log a thought as soon as it pops into your head. It wants people to think of the Stream Ring as a “mouse for voice,” and says the mic will always be able to pick up your voice clearly in a noisy room. Crucially, it isn’t always listening either, only activating when you hold the touchpad.

As for the chatbot, it’s designed by default to somewhat mimic your own voice using AI, a feature Sandbar calls Inner Voice. You can update it if you think it sounds off, or if the whole concept creeps you out you can also switch to a non-personalized voice. Away from the core voice note functionality, the Stream Ring can also be used to control media playback using gestures, and Sandbar says it’s compatible with any headphones.

Sandbar will offer a free plan that includes unlimited notes but limits AI interactions. For $10 per month you can upgrade to a Stream Pro subscription (you get three months for free with a new purchase), which enables unlimited chats and immediate access to any new features. Sandbar says your data is encrypted at rest and in transit and it will not sell your information to other companies. You can also delete data stored in the app at any time.

Other smart rings have a seamless interactive experience built around AI, and the Stream Ring isn’t going down the health tracking route that many other in this increasingly crowded space market themselves on. But if the transcription feature works as reliably as advertised and Sandbar’s AI proves to be a genuinely useful assistant, the Stream Ring could be a useful accessory that doesn’t get in the way when it isn’t needed.

The Stream Ring is available in sizes 5-13 and is designed to be worn on your index finger. Sandbar promises “all-day battery life” but doesn’t go into specifics. It’s expected to start shipping next summer in the US and costs $249.
