Overview
Limitless (formerly Rewind AI) was a San Francisco-based AI wearable company that developed the Limitless Pendant, a USD 99 wearable device that recorded, transcribed, and summarized conversations. Founded in 2020 by Dan Siroker (co-founder of Optimizely) and Brett Bejcek, the company pivoted from desktop-based meeting recording software to hardware in 2024.
The pendant featured beam-forming microphones, 100-hour battery life, and encrypted cloud storage. In December 2025, Meta platforms acquired Limitless; hardware sales ceased and the team joined Reality Labs' wearables organization.
