We have moved beyond solely depending on smartphones for our mobile computing requirements. iPhones and Android devices are frequently complemented by unique wearable accessories: Wireless earphones allow us to enjoy music, converse with friends, and interact with AI. Smartwatches showcase notifications, operate applications, and track crucial health and fitness metrics. Smart rings can also assist with the latter, minimizing the necessity for a wrist wearable. In this competitive environment where concepts are frequently reused, the wearable brand Pebble has introduced an unexpected accessory; a ring devoid of health sensors. Instead, the Pebble Index 01 is a smart AI ring designed to help you effortlessly remember things by capturing your thoughts through voice and transmitting that information to your smartphone.
The ring is capable of storing five minutes of voice recordings and utilizes private AI models to transcribe those thoughts on iPhone or Android devices via the Pebble app. The surprises continue: The Pebble Index 01 boasts a battery life so extensive that you won’t ever need to recharge it. Simply return it to Pebble for recycling when needed, and you might consider ordering a new one. The price is reasonable as well, with the Pebble Index 01 starting at $75 during the preorder phase. Once shipping commences in March 2026, the price will rise to $99. The Pebble Index 01 comes in eight ring sizes (6 to 13) and three colors (silver, gold, and black).
Regarding the actual battery life, the Pebble Index 01 can last up to two years with typical use, assuming you utilize it around 10-20 times daily to record thoughts of 3-6 seconds. Overall, the ring can capture approximately 12-15 hours of audio throughout its lifespan.
How secure is the Pebble Index 01’s AI?
Pebble chose a “single-use” design rather than a rechargeable battery like health-monitoring smart rings for usability reasons. The company aimed to ensure the device is perpetually ready for use; users should not need to worry about charging it. Additionally, eliminating charging capabilities helped Pebble reduce costs. The Pebble Index 01 is equipped with a button, a microphone, a Bluetooth chip, and built-in memory that stores thoughts when a phone is not nearby. The wearable is constructed from stainless steel 316 and silicone rubber (for the button), and it is water-resistant up to one meter (3.2 feet).
To operate the Pebble Index 01, wear it on your index finger with the button easily accessible by your thumb. Press the button to record your thoughts wherever you are. The device doesn’t have always-on features, with Pebble stating it is “exceptionally private and secure.” An open-source speech-to-text system manages voice recordings. AI models function locally on the phone, with support for 99 languages, via the Pebble app. The link between the smart ring and your iPhone or Android device is encrypted, and the entire operation works offline with no cloud processing necessary. However, optional cloud storage may be utilized, and in the future, it might also be encrypted.
The primary function of the Pebble Index 01 is to capture voice notes and save them on your phone, where you can incorporate them into notes and reminders. The button supports both single and double clicks, allowing for some customization: One of the gestures could be linked to music playback, smartphone control, and even ChatGPT access in the future.
