Limitless began as Rewind AI, an a16z-backed company that originally recorded a user's entire desktop screen activity to build a searchable personal memory, before pivoting in April 2024 to a physical $99 pendant specifically recording conversations and meetings, supporting transcription across 103 languages, and drawing more than ten thousand preorders within its first day.
That hardware chapter proved short-lived: Meta acquired Limitless in December 2025, absorbing the team into its Reality Labs division to work on AI features for Ray-Ban smart glasses, and wound down hardware pendant sales immediately afterward, ending the standalone device as a purchasable product.
Given that acquisition, anyone researching Limitless today should confirm current software availability directly rather than assuming the original pendant-plus-app experience still operates as it did before Meta's acquisition; the underlying conversation-recording concept appears set to continue inside Meta's wearable hardware line rather than as an independent product.
