After rebooting the Pebble smartwatch brand, founder Eric Migicovsky is expanding his company’s device lineup with a new smart wearable: an AI-powered smart ring known as Index 01. Named for the finger where the ring is meant to be worn, the new $75 ring is not meant to be a competitor to always-on, always-listening AI devices, like the AI pendant Friend, but instead offers a way to record quick notes and reminders with a press of a button on the ring’s side.
AI only comes into play via the open source, speech-to-text, and AI models that run locally on your smartphone through the Pebble mobile app. That is, if the ring’s button is not being pressed, it’s not recording. (And this is a press-and-hold gesture, too, which means you can’t start the ring’s recording and then let go to surreptitiously record a conversation.)

You can wear the stainless steel ring while in the shower, washing hands, doing dishes, or in the rain, but you would have to take it off for other water-related activities, like swimming. At launch, it’s water-resistant to 1 meter.
The ring is also not a fitness tracker or sleep monitor. It doesn’t record details about your heart rate or health. And it’s not there to be your AI friend.
“I’m not trying to build some AI assistant thing,” Migicovsky told TechCrunch in an interview. “I build things that solve one main problem, and they solve it really well,” he explains. “I think of [the ring] as external memory for my brain…that’s what this is. It’s always with you.”
Plus, the ring has been designed to be highly reliable and privacy-preserving, he says, as all your thoughts are stored on your phone, not in the cloud. There is no subscription.
Migicovsky’s ring enters a growing market for voice-note wearables. Last month, Sandbar, a New York-based startup founded by former Meta employees, unveiled its Stream Ring, which also lets users record thoughts via a touch-activated microphone. However, unlike Index 01’s no-subscription model, Sandbar’s $249 ring offers both a free tier with limited AI interactions and a $10-per-month Stream Pro subscription for unlimited chats and early access to features. The Stream Ring is expected to ship next summer.

Migicovsky has been wearing his own ring for three months now and says he cannot imagine going back to a world where he doesn’t always have a memory device with him.
