The aluminum ring has a touch-sensitive top panel and a microphone that is off by default and proximity-tuned, so a wearer lifts a hand toward the face and whispers to record, with the audio transcribed to a companion iOS app that also offers conversational AI chat and media controls; it has no display, no camera, and no health sensors, explicitly distinguishing it from an Oura-style health ring. It is priced at $249 in silver and $299 in gold on pre-order with a $10-per-month Pro subscription, and the company has raised about $36 million, including a $23 million Series A in March 2026 led by Adjacent and Kindred Ventures after a $13 million round in November 2025. The registry records it at pilot and pre-commercial maturity as a deliberate cap-flag: as of mid-2026 it is pre-order only with a summer-2026 ship target and a sold-out first batch, funded and productized but not yet across the shipping line, so it is not classified commercial until general delivery is confirmed.
