Meta’s Muse agentic assistant is one of the most talked-about AI tools, but you may not want to let it control your Facebook Marketplace negotiations. One user reported that the AI assistant shared their home address without asking for the user's permission.
Tech YouTuber Matt Robb shared their experience on Threads after a buyer showed up at their property, with the seller unaware a deal had been made. Robb said, “So muse handled my Facebook marketplace today. Just found out it told people my address and agreed a lowball price and then they showed up without it even telling me until late tonight that it messed up.”
A screenshot of the conversation showed Muse messaging late in the evening to say it was "bad news" on the item's pickup. Muse outlined how it had invited the buyer over, noting that the person messaged “a bunch of times” while waiting at the property. It apologized for not telling Robb someone was waiting.

Muse apologized to the buyer, noting, “I’ve sent him an apology from your account, owning it and offering to try again another day.” It also told Robb, “I should probably stop the auto-replies from claiming you’re home when I can’t verify that. Want me to change the pickup replies so they don’t promise you’re there?”
The experience was frustrating for the seller, who said, “AI agents are impressive right up until they're confidently handing strangers your address.” He noted how he didn’t realize the tool would pull his address and present it to a stranger, and it remains unclear where Muse obtained that information.
Meta has been embroiled in a privacy scandal over the last week, where an Inc writer found that Muse was reading their personal messages without their permission. The tool told the writer it didn’t have access to full messages, despite evidence to the contrary showing it was capable of reading back-and-forth conversations.
At launch, Meta said Muse is built "from the ground up to be a safe, secure, private, and widely available personal AI agent." Meta did not immediately respond to PCMag's request for comment.
