Limitless

Limitless is an AI-powered personal memory tool that combines a wearable pendant with a software platform to capture, transcribe, and organize everything you hear throughout your day. The physical Limitless Pendant is a small, discreet wearable that records conversations, meetings, lectures, and spontaneous ideas, while the companion app processes everything into searchable, actionable intelligence.

The core value proposition is augmented memory. Limitless captures audio throughout your day and uses AI to generate meeting summaries, extract action items, surface key decisions, and make your entire conversational history searchable. You can ask questions like 'What did Sarah say about the project timeline last Tuesday?' and get instant, accurate answers drawn from your recorded conversations.

The Limitless Pendant is designed for all-day wear — it's lightweight, has long battery life, and operates with consent-aware features including LED indicators that signal when recording is active. The hardware connects to the Limitless app via Bluetooth, with processing handled in the cloud for accuracy and speed.

Beyond the pendant, Limitless also works as a software-only meeting assistant that joins virtual calls on Zoom, Google Meet, and Microsoft Teams. This dual approach — hardware for in-person conversations and software for virtual meetings — provides comprehensive coverage across all communication contexts.

Founded by Dan Siroker (former CEO of Optimizely), Limitless was acquired by Meta in December 2025. Following the acquisition, Meta stopped selling new Pendants and waived subscription fees for existing users, granting them free Unlimited plan access. New units are no longer available for purchase directly, though the software platform continues operating for existing users.
