Limitless

Limitless is the company behind the Pendant, a small wearable that captures conversations and meetings so they can be searched, summarised and turned into notes afterwards. It was started five years ago by Dan Siroker and a team drawn from Apple, Google, Meta, Spotify, Amazon and SpaceX, with the stated aim of augmenting memory rather than replacing human intelligence.

The product pairs the clip-on pendant with desktop and mobile applications that also index mail and calendar entries. Limitless has since been acquired by Meta, which is folding the team into its AI wearables work: the Pendant is no longer sold to new customers, existing owners keep support through 2026 with the unlimited plan free, and software features such as Rewind are being discontinued.
