Stream provides a finger‑worn smart ring that enables private, hands‑free voice note capture and media control. Users activate a directional microphone by holding the touchpad, receive silent haptic confirmation, and have recordings transcribed, organized, and synced through an iOS app, with optional AI‑driven responses. The ring connects via Bluetooth Low Energy, stores data locally, and offers a subscription for unlimited conversational interactions.

Problem
Busy professionals and creators often need to capture fleeting ideas instantly, but pulling out a phone or laptop interrupts workflow and can be noisy or insecure in public settings. Existing voice assistants require wake words, constant listening, or bulky hardware, limiting privacy and speed of capture.
Solution
Stream delivers a finger‑worn smart ring that acts as a private, always‑ready voice interface. Users hold the touchpad to activate a directional microphone, speak a note, and release to confirm, receiving silent haptic feedback. Captured audio is transcribed and organized in the companion iOS app, where notes can be edited, linked, and searched. An on‑device “Inner Voice” provides personalized spoken responses and can retrieve web information when earbuds are connected. All interactions are encrypted, stored locally for offline access, and synced to the cloud when online. The ring also supports gesture‑based media controls, making it a multifunctional extension for on‑the‑go productivity without relying on a phone.
Target Audience
The primary users are knowledge workers, creators, and executives who need rapid, discreet note‑taking and media control while on the move, as well as developers building voice‑centric workflows that benefit from a private wearable interface.
