Meta shares rallied more than 5% on Wednesday, after the company debuted its new AI assistant, Muse.
Muse "is designed around the way people already communicate, so talking to it works just like messaging another person, in the Muse app or directly in WhatsApp," Meta said on Tuesday.
Privacy
Chief executive Mark Zuckerberg used a video message to highlight the tool's privacy and security features.
"We built a Secure Credential Store for your passwords and credit cards so Muse can't read this information," Zuckerberg said, adding that Muse checks directly with users before taking sensitive actions such as making payments or sending messages.
Zuckerberg said the encryption underpinning Muse is modelled on WhatsApp, "where even Meta can't see the messages that you send."
Clawing back losses
Meta shares have now recovered most of the declines they suffered earlier this year.
Even after Wednesday's rally, the stock remains down roughly 1% for the year to date, leaving investors to judge whether Muse can be the catalyst that finally turns 2026 into a positive year for the shares.
