Architectureepisodic-buffer / Meeting-Focused Wearable Transcription
DetailsThe Limitless Pendant is a small clip-on device that records up to 35 hours of meeting audio, transcribing in real-time and generating concise AI summaries searchable via the companion app. Unlike the earlier Rewind desktop product, the pendant is meeting-focused and cloud-processed. Launched at $99 in April 2024 as Rewind rebranded to Limitless; Meta acquired the company in December 2025 and ended new hardware sales, absorbing the team into Reality Labs.
