Opal is a wearable AI assistant you wear as a Bangle.
Opal is a wearable AI assistant: an open metal Bangle, about 19 mm wide, with a microphone, a speaker and an AI inside. It listens to your day, remembers what was said as notes you can search, and acts for you, putting the meeting on your calendar or sending the follow-up email. It has no screen. Jewelry that you can trust. Your life in context.
How Opal works
You wear it. Opal hears the room while you live in it: meetings, rounds, the conversation on the walk to the car. You never press record.
What was said becomes notes you can search, ask about, and hand off. The name you forgot. The thing you promised to follow up on.
Say it once, on your wrist, and Opal has its own computer in the cloud that gets things done: it puts the meeting on your calendar, sends the follow-up email, books the table. Like instinct, but it acts.
Your audio is yours. Opal is built privacy first, with processing on the device wherever it can be, so what you hear does not become someone else's data.
Opal versus a smartwatch, a phone, or an AI pin
A smartwatch shows notifications and waits for a tap. A phone is in a pocket, off, when the conversation happens. An AI pin clips to a shirt. Opal is a Bangle, a piece of jewelry you would wear anyway, and it does its work without a screen: it listens, remembers, and acts, so the interface is you talking.

Why we built it
Struggle is where insights live. Opal does not think for you. It catches you thinking out loud.
