According to reports, the "super sensing" glasses would use built-in cameras and microphones to take photographs every few seconds while continuously recording audio, allowing AI to help users recall conversations, objects and events from throughout the day.
The technology is designed to let wearers query what they have seen or heard, effectively creating a searchable record of their daily experiences.
The reported project has already sparked internal debate over privacy, particularly concerning people who may be recorded without their knowledge.
Meta's existing AI smart glasses feature an LED indicator that lights up whenever users take photos or record video. However, multiple reports claim executives are considering leaving the indicator inactive while the super-sensing functions are operating, making it harder for bystanders to know when information is being captured.
Those plans could still change.
Meta declined to comment on what it described as "internal prototypes" but said its hardware development focuses on "privacy built in from the ground up".
The company is also reportedly considering bringing the super-sensing features to existing Meta smart glasses through a software update.
Chief executive Mark Zuckerberg has repeatedly outlined his vision for AI glasses eventually replacing smartphones as people's primary computing device.
During Meta's first-quarter earnings call, Zuckerberg said he wanted smart glasses to evolve from "being able to answer questions to being able to be a personal agent that's with you all day long, helping you remember things and achieve your goals".
According to reports, one proposal would see raw photos and audio discarded after metadata is extracted and uploaded for AI processing, reducing the amount of personal content stored by Meta.
The company is also said to be exploring whether information collected through the glasses could be used to train its AI models as it competes with rivals including OpenAI, Google and Anthropic.
Privacy experts have warned that always-on wearable devices could create new legal and regulatory challenges.
Woodrow Hartzog, professor of law at Boston University School of Law, said: "There's no one law that addresses all the different dangerous ways these tools have been designed and built.
"Lawmakers have to take this seriously and update to accommodate this reality of always-on, always-seeing devices."
Meta has increasingly shifted its hardware strategy towards AI-powered glasses following the commercial success of its Ray-Ban smart glasses, while scaling back its investment in its metaverse ambitions.
