Get ready for a game-changer! Eric Migicovsky, the mastermind behind the Pebble smartwatch brand, is back with a revolutionary idea: an AI-powered smart ring called Index 01. But here's the twist - it's not your typical AI assistant.
Priced at just $75, this sleek stainless steel ring is designed to be your personal memory aid, capturing quick notes and reminders with a simple press of a button. Unlike always-on AI devices, Index 01 respects your privacy and only records when you want it to.
The magic happens through open-source speech-to-text models running on your smartphone via the Pebble app. And here's the part most people miss - it's a press-and-hold gesture, so no sneaky recordings!
Water-resistant up to 1 meter, you can wear it in the shower or during light activities, but it's not meant for swimming. And it's not a fitness tracker or sleep monitor either - this ring keeps its focus on one main problem: helping you remember those fleeting ideas and moments.
"I build things that solve one main problem, and they solve it really well," Migicovsky explains. He sees the ring as an external memory for your brain, always by your side.
But here's where it gets controversial... With all your thoughts stored on your phone, not in the cloud, and no subscription fees, Migicovsky claims the ring is highly reliable and privacy-preserving.
In a growing market for voice-note wearables, Index 01 stands out with its no-subscription model. Compared to competitors like Sandbar's Stream Ring, which offers a free tier and a $10/month subscription, Index 01 keeps it simple and affordable.
Migicovsky has been testing his own ring for three months and can't imagine going back. "The problem is that during the day, I get ideas or I remember something, and if I don't write it down that second, I forget it," he says. The ring solves this, and with a battery life of years, it's always ready to capture those fleeting moments.
The ring supports up to 14 hours of recording, and Migicovsky estimates getting two years of usage with his daily 10-20 recordings of 3-6 seconds each. When the battery finally dies, you can recycle it through the company.
With support for over 100 languages and on-device memory, the ring is versatile. You can even verify your recordings on a Pebble smartwatch or other brands, and integrate with calendaring systems or apps like Notion. And the best part? The ring's software is open-source, inviting the community to hack and customize it further.
The ring's button is already programmable, offering more than just recording. You can control your music, camera shutter, or send messages through Beeper, another Migicovsky creation.
Migicovsky acknowledges the challenges of hardware, having seen Pebble's exit to Fitbit and its subsequent acquisition by Google. But he's taking a different approach with his new company, Core Devices, a small, self-funded team focused on sustainability.
With the Pebble 2 Duo smartwatch already sold out and the upgraded Pebble Time 2 pre-orders reaching 25,000, Core Devices is off to a strong start. And the Index 01 pre-order offer ends in March 2026, with the price increasing to $99 afterward.
So, what do you think? Is this smart ring a game-changer or just another gadget? We'd love to hear your thoughts in the comments!
