Sandbar Launches Stream, a Voice-Driven AI Ring for Thinking Out Loud

• Stream is a $249 smart ring and AI app that turns speech into notes, outlines, and structured thoughts.
• The system activates with a touch, uses a personalized voice model, and begins U.S. shipping in Summer 2026.

Sandbar has debuted its flagship product Stream, a smart ring and companion AI app that turns your voice into notes, outlines, and ideas. The company has raised $13 million in funding from True Ventures, Upfront Ventures, and Betaworks, according to TechCrunch, and was founded by veterans of CTRL-Labs, a human-computer interface startup acquired by Meta in 2019.

The Stream Ring is worn on your dominant hand. Pressing its touchpad turns on the mic, and letting go turns it off. You can also use the touchpad for gestures to play, skip, or control volume. The mic picks up your voice clearly, even in loud places, and doesn’t listen unless you're pressing it. The ring comes in Matte Silver and Polished Gold.

The Stream app connects with the Ring to turn voice into notes, lists, and outlines. You can speak while the app is open or save thoughts for later if it’s not. Users will be able to use it to plan their day, work through ideas, or explore a topic out loud. The default voice, called Inner Voice, is partially based on your own voice when you first use the app. It’s meant to feel like talking to yourself, and you can update, delete, or switch to a different voice anytime in settings.

The Stream Ring is available for preorder at $249. It comes with a three-month subscription to Stream Pro, which gives users unlimited interactions and early features. A free tier for the app is also available, offering unlimited note-taking and limited chat access. The company says shipping will begin in the U.S. in the Summer of 2026, with limited inventory at launch.

🌀 Tom’s Take:

Sandbar’s Stream Ring enters what’s quickly becoming a crowded field of AI wearables, alongside devices like Friend, Pendant, and Bee. The ring format stands out and clearly takes cues from the success of products like Oura.
