Meta Extends Muse AI Agent to Smartwatches as Infrastructure Chief Santosh Janardhan Steps Down

Meta is bringing its Muse AI agent to Apple Watch and Android’s Wear OS, letting users interact with the assistant through voice calls, text messages or dictation directly from their wrist, the company announced on Monday.

The move follows the debut of a dedicated iPad app a month earlier, after Muse first arrived on the App Store in September, and signals Meta’s ambition to make the AI assistant a central part of its ecosystem. Like many rival consumer AI agents, Muse can connect to users’ accounts to manage email, meetings and bills, and handle tasks such as booking reservations, ordering groceries and making purchases. Users can also customise their Muse avatar as a person, animal or other character.

Meta has added features rapidly. Last week, US users gained the ability to video chat with their Muse avatar, which hears users and responds in real time with expressions and gestures, though it cannot see them. Days later, Meta introduced Spaces, topic-specific conversations that function as mini apps built on the fly, where Muse works towards a particular goal for the user. Muse also became one of only 12 mobile apps to pass 10 million US downloads within 40 days of release.

Separately, Santosh Janardhan, Meta’s longtime head of infrastructure and co-head of engineering, is stepping down and is expected to leave next year. A Meta representative said he will remain during the transition and move into an advisory role on Meta Compute, the initiative he was appointed to lead earlier this year to scale the company’s data centre investments. The reason for his departure was not specified, though his internal memo reportedly referred to passing the baton.

Janardhan, who joined Meta in 2009, will be succeeded by Dave Brown, who became vice president of infrastructure this year after 19 years at Amazon focused on compute, cloud and AI.
