How does it work? People usually wear it on the index finger. Inside the ring is a button, a microphone, a Bluetooth chip, memory, and a battery that lasts for years. Click the button with your thumb, talk into the mic, and it records to internal memory. When your phone is in range, the recording is streamed to the Pebble app. It's converted to text on-device, then processed by an on-device large language model (LLM) which selects an action to take (create note, add to reminders, etc).

Is it secure and private? Yes, extremely. The connection between ring and phone is encrypted. Recordings are processed locally on your phone in the open-source Pebble app. The app works offline (no internet connection) and does not require a cloud service. An optional cloud storage system for backing up recordings is available.
