Muse is Meta's personal AI agent: it is designed to perform tasks, not just answer questions. The service officially launched in Japan on October 23, 2026, after its North American debut. It is available through mobile apps and the web, with a free usage tier.[1][2]
The pitch is wonderfully absurd: instead of opening five apps and explaining your situation five times, tell one assistant what you want. Apparently the new hire lives in a cloud computer and does not clock out when you close the app. Management will be delighted. Privacy teams will have questions.
Does it really move between services?
Meta says Muse can plan a task, browse sites, fill in forms and move work forward across connected services. Travel arrangements, email management and calendar coordination are examples. Longer jobs can continue in the background; the agent returns when it needs approval or has an update.[1][3]
Services mentioned for Japan include Gmail, Google Calendar and Instagram. Other integrations have been announced, but availability depends on the country, account and rollout stage.[1] Think of Muse as an assistant allowed to visit certain offices, rather than a universal key to every locked door on your computer.
Can Muse take over my ChatGPT projects?
Do not assume that it can. An agent that connects to several apps does not automatically receive access to private projects or conversation histories inside a competing AI product. The Meta materials reviewed here do not establish a feature that imports and operates entire ChatGPT projects.[1][2]
Permissions matter. Allowing an agent to read an inbox is different from letting it send mail. The appeal is cross-app execution within granted access, not unrestricted access to everything you have ever told an AI.[3]
Free tier, Instagram sign-in and the one-billion-token invite
The Android listing is “Muse from Meta,” package ID com.facebook.aura. Checking the developer and package is smarter than installing the first lookalike that search presents.[4] Meta confirms that Muse has a free limit that refreshes, plus paid plans for heavier use.[2]
Users have reported signing up via an existing Meta account without providing a card. The referral prompt circulated in Japan says entering a code under Settings within 48 hours of joining awards one billion Muse tokens to each person, the referrer and the newcomer.[5]
Referral code (disclosure: the referrer benefits too): A96MB6. Sign up through Muse's official site, then enter the code in Settings within 48 hours of joining. The invitation states that both the newcomer and the referrer receive one billion Muse tokens when eligible. The article's referrer may therefore benefit when you use this code. Check whether it is still valid, how many uses remain and whether the reward is credited in your account.[5]
That is an excellent number for a headline and a terrible substitute for the fine print. Muse tokens should not be treated as automatically equivalent to one billion general-purpose language-model input tokens. The precise spending rules, expiry and interaction with the free tier should be checked in the account. Likewise, official pages confirm refreshing free usage but do not establish the claimed weekly reset schedule.[2]
What should you delegate first?
Start with reversible work: compare travel options, assemble a source-linked research table or prepare email drafts. Review the output, then grant narrower permissions for the next step. You can keep actual sending, purchasing and other consequential decisions behind a human approval step.
Meta describes an activity history, adjustable permissions and approvals for sensitive actions.[3] Its Play listing also warns that the system may make mistakes or take unexpected actions.[4]
The real question is not whether you got a billion tokens. It is whether your task actually got finished. Muse is less a magic portal into every AI project and more a promising junior colleague with access badges. Give it a sensible assignment before handing over the company credit card.
