AI Pendant Form Factor Absorbed
Why Meta bought Limitless
This is a distribution story more than a device story. A chest or neck gadget has to convince people to buy, charge, wear, and explain one more thing, while glasses and earbuds already sit on the face and ears all day with microphones, speakers, batteries, companion apps, and retail reach. Once big platforms can add memory, transcription, and AI assistance into those existing products, the standalone pendant stops looking like a category and starts looking like a feature set.

The market has already voted this way in practice. Meta bought Limitless in December 2025 and stopped new pendant sales, then moved the team into Reality Labs for AI wearables work tied to Ray-Ban Meta smart glasses. Humane was sold to HP in February 2025 and its AI Pin was discontinued, while Friend shifted from pendant hardware toward a web chatbot.

The product logic favors incumbent form factors. Earbuds and glasses already solve audio input, output, comfort, charging habits, and everyday social acceptance. A pendant still has to manage consent friction around recording nearby people, and for work meetings software only capture on the desktop is often simpler because it can record system audio without introducing a visible device into the room.

The remaining opening is narrower and more practical. Plaud has kept growing, reaching an estimated $250M annualized revenue by September 2025, because it sells into offline workflows like doctors, lawyers, and field sales where a phone or laptop is not always the right capture tool. That looks less like a mass consumer wearable category and more like a specialized notetaking appliance business.
From here, ambient AI capture is likely to get bundled into the devices people already wear, then linked to phone and desktop software that organizes transcripts, memories, and actions across contexts. That pushes startups away from inventing new body locations and toward owning the software layer, or serving narrow offline jobs where dedicated capture hardware still beats glasses, earbuds, or a laptop.
