Meta introduces Muse, an AI agent powered by Muse Spark

Meta describes Muse as an agent designed to take action on tasks rather than only answer questions.[1] It says the tool can help users turn long-term goals into action plans.[1] Muse is powered by Muse Spark, which Meta calls its most capable model to date.[1] Meta says Muse can open a browser, fill out forms and negotiate on users’ behalf.[1] It can continue working after users close the app and return when it needs approval.[1] For professionals evaluating an agent, those details point to a tool intended to handle steps in a task, while leaving some decisions with the user.

Meta says Muse remembers information users share and can use it to make unprompted suggestions.[1] The company says the agent runs on Muse Secure VM, a dedicated virtual machine that houses the agent and a user’s data.[1] Users decide which apps Muse connects to and how much access it receives.[1] Meta says Muse can ask for approval before sending an email or making a purchase.[1] It also says users can opt out of having their interactions used to train its AI models, and that Muse does not share conversations or VM data with Meta’s advertising systems.[1] These controls make app permissions, approval prompts and data settings practical items to review before using the agent for work.

Meta said Muse was rolling out in the United States on iOS, Android and muse.ai.[1] The company said it would be free for most needs, with subscriptions available for users who want to do more.[1] Meta also said anyone can use Muse out of the box without technical experience.[1] The company said Muse was coming soon to AI glasses, while Shop Pay and 1Password support were also coming soon.[1] Meta said it planned to introduce Muse Confidential VM later in 2026, with encryption keys held only by the user.[1] These are stated plans, rather than features the evidence says are already available.

Meta said Muse was the first AI agent covered by Link’s purchase protections.[1] Business Insider reported that Alexandr Wang promoted Muse integrations with Shopify, PayPal, Expedia and Instacart.[4] That combination makes shopping and other online transactions part of the product’s stated use cases, while Meta says Muse can seek approval before making a purchase.[1] Business Insider reported that Wang posted more than 300 times on X after Muse launched, including more than 100 posts in one five-day period.[4] The outlet said the posts often used memes and sometimes took jabs at AI rivals.[4] Wang wrote that Muse was built to help people build the world they want.[2]
