Meta is testing a switch that would replace Meta AI on its smart glasses with Muse, its new AI agent. Reverse engineer Jane Manchun Wong posted the setup screen on X, and Android Authority reported the find on Wednesday.

The screen asks, "Enable Impacc as your glasses assistant?" Impacc looks like an internal codename for Muse. The prompt says Muse is in beta, and that you can switch back to Meta AI whenever you like.

It also lists what the beta can't do yet: Live AI, navigation, Shazam song identification, Strava and Health Connect, the Android system that lets fitness apps share data. Strava and Health Connect would tie the glasses to your workouts. Shazam would let them name the song playing in the room. A runner could, in principle, start a Strava run and get directions home without touching a phone.

Live AI, the mode where the glasses keep watching and you keep talking without saying the wake word each time, is also on the list. On today's Ray-Ban Meta glasses it lasts about 30 minutes, and one of the Gen 3 rumors we track has it running for hours.

Navigation has been on Meta's list before. When Meta announced its display-free Meta Glasses on June 23, it said walking directions were coming soon. What shipped was audio guidance as you walk, one step short of turn-by-turn. Three months later, navigation turns up again, on a list of Muse features that aren't ready.

A second find from Wong shows Meta building "Meta Pay for Muse," a wallet inside the agent. It works with Meta Pay, Stripe's Link and Shop Pay. The screens suggest it's meant to let Muse make purchases on your behalf, which is a bigger step than answering a question about what you're looking at.

Today the glasses answer through Meta AI, which has run on Muse Spark, Meta's latest model, since Meta Glasses launched. The test would swap that assistant for Muse itself, a more autonomous one that can act rather than just reply. Meta hasn't said how the two relate on the glasses, or whether the older Ray-Ban Meta pairs would get the option.

A setup screen in a test build shows what a company is trying, and Meta hasn't announced Muse for its glasses. Nothing in Wong's posts says what will ship, or when. They landed on the morning of Meta Connect, the company's yearly keynote, where new glasses are expected.
