What's Stream?
Stream is a self extension for capturing thoughts & building ideas. It's great for talking through things in-the-moment—from developing an idea, to exploring a topic, to planning your day.
Stream speaks using an Inner Voice—a voice partially personalized on your own, that feels a bit like talking with yourself. You can hear Stream via your phone speaker or paired earbuds.
Stream can also create notes from your conversations. This can be fast & simple, like checking off a grocery list, to surprisingly powerful, like turning an entire conversation into an outline.
As a self extension, Stream is designed to support your thinking through thoughtful questions and intelligent responses, rather than having an independent identity of its own.

Why a Ring?
Stream Ring is the mouse for voice. It's always available, so you can engage with thoughts without wake words or pulling out your phone. It keeps you in control of the conversation; listening as you hold and interrupting with a tap. The personal mic picks up your voice clearly, even in loud places. And you can effortlessly resume your music, skip songs, and change volume with familiar gestures.
Stream Ring is more ergonomic, intuitive, and private than fiddling with earbud controls. You can also save or update notes without earbuds, confirmed with in-ring haptic vibrations.
No need for wake words, lock screens, always-on mics, getting spoken over, or talking loudly in public. Stream Ring unlocks fast, private, and effortless voice interactions anywhere.

Is the Ring always recording?
No—the personal mic only activates when you hold the touchpad. It’s designed for capturing your own voice.

Does Stream require a subscription?
Stream Ring includes 3 months of Stream Pro—unlimited interactions and early features—and continues at $10/mo for preorder members.
Stream's free tier includes unlimited notes and limited chats. You can switch tiers anytime, and your data is always accessible on any tier, no subscription required.

Does Stream require earbuds?
Stream works with any pair of earbuds, or without earbuds at all.
Stream can reply when the app is open or if earbuds are connected. Otherwise, Stream Ring will quietly save what you share and confirm with in-ring haptics.

Does Stream require a Stream Ring?
A Stream Ring is needed to create your Stream for the first time. If you don't have your Stream Ring, you can still use on-screen inputs within the Stream iOS app.

Is internet required?
Stream can save a limited number of interactions without an internet connection. Media controls work with or without internet.

What's Inner Voice?
Inner Voice is Stream's default voice. It's partially personalized based on your own voice when you use Stream for the first time, and it's designed to feel a bit like talking with yourself. It can be updated, deleted, or changed to a non-personalized voice in app settings.
