Muse Review: Meta's Personal AI Agent, Its Availability in Hong Kong and the Real Value of the 1 Billion Token Referral Reward

Muse is a personal AI agent launched by Meta Platforms on 8 September 2026, running on Meta's own Muse Spark model. The user describes a goal in conversation and Muse draws up a plan and carries it out, including opening a browser, completing forms, sending email, booking travel and negotiating on the user's behalf. Muse continues working after the app is closed, and notifies the user when circumstances change or approval is required.

Muse is available through the iOS and Android apps, the muse.ai website and WhatsApp. Users sign in with a Meta account, which may be created from Facebook, Instagram, an email address or a phone number; the Muse Supplemental Terms require users to be 18 or over.

Meta launched Muse in the United States on 8 September 2026, and the app is also listed on the Canadian App Store; on 23 October Meta launched it in Japan, describing Japan as its first market outside North America. As of 24 October 2026 the Muse app is not available on the Hong Kong App Store, Meta's help centre states that Muse is not yet offered in all locations, and no Hong Kong launch date has been announced.

The Japanese launch is of no practical help to Hong Kong residents: the app is listed only in the American, Canadian and Japanese stores, and Meta's subscription guidance requires users to be in a country where Muse is offered. Circumventing the restriction with a VPN or an overseas store account is inadvisable, as the Muse terms allow Meta to suspend or end access at any time, which may also affect the user's Meta account.

Everyday uses of Muse include sorting and replying to email, resolving diary clashes, setting reminders, booking restaurants, tracking prices and shopping on the user's behalf, reviewing subscriptions and budgets, and drawing up exercise or meal plans from data the user provides. Muse remembers details the user has mentioned and offers suggestions unprompted, and the user may ask it to delete specific memories.

Users decide which services to connect, including email, calendar, Instagram, Facebook, and finance and health apps, and may set the permission for each, for example reading email only or also sending it. Payments are handled by Link by Stripe, which generates a one-time card number so that the real card details need not be disclosed to Muse. Meta cautions that Muse may make mistakes or take unexpected actions, and important matters should be verified by the user.

Each user's Muse runs on a dedicated virtual machine in Meta's cloud, Muse Secure VM, where the credentials for connected services are also stored. A separate Sentinel agent on the same virtual machine must approve anything Muse sends to the internet; Muse cannot see the user's passwords or payment details, must obtain consent before sensitive actions such as sending email or making purchases, and keeps a complete activity record.

Meta states that Muse does not provide conversations or virtual machine data to its ad systems, and users may opt out of their interactions being used to train Meta's models. A Confidential VM, encrypted with a key held only by the user, is expected later in 2026. Muse must nonetheless read email and act within the user's accounts to be of use, and we recommend granting the minimum permissions at first and widening them gradually as needed.

Muse may be used free of charge, subject to a usage limit. Meta's help centre lists two paid plans: Power at US$20 a month (about HK$157) with 500 million Muse tokens a week, and Maximum at US$100 a month (about HK$784) with 3 billion a week. The plans have identical features and differ only in usage. Plans renew automatically each month on the purchase date and may be cancelled at any time. Meta does not publish the free allowance; once it is used up, the user may wait for it to reset, subscribe or buy additional tokens.

Meta's help centre states that separately purchased tokens and promotional tokens do not expire, while unused weekly allowance does not carry over. Except where the law requires otherwise, tokens cannot be transferred or refunded, carry no cash value and apply only to Muse features. The Muse terms allow promotional credits to carry a stated expiry, so users should note the date shown beside the balance.

Meta's official @meta.ai account explained on Threads on 22 September 2026 that when a new user redeems a code in Settings within 48 hours of joining, that user receives 1 billion tokens, and that each code may be used 20 to 30 times depending on the stage of the rollout. I4MGRC is our referral code.

At official plan prices, 1 billion tokens equal two weeks of the Power allowance or roughly two and a third days of Maximum. The Power plan works out at US$20 × 12 ÷ 52, or US$4.62 a week for 500 million tokens, so 1 billion are worth about US$9.23 (about HK$72); on the Maximum plan they are worth about US$7.69 (about HK$60). The reward is additional usage, not cash.

Once Muse launches in Hong Kong, users may open Muse's join page with the Claim button on this page, create or sign in to a Meta account and complete onboarding, then, within 48 hours of joining, open Settings, select Redeem code and enter I4MGRC. The link does not carry the code, which must be entered by hand; the reward applies only to new users, and an account past its 48 hours cannot claim it later.

The token balance should be checked in Settings immediately after redemption. If Muse reports that the code has no uses left, it has reached its limit of 20 to 30, and we will update the code on this page. We recommend using the free allowance first and keeping the 1 billion tokens for substantial work, such as planning and booking an entire trip.

As of 24 October 2026, Muse holds 331,897 ratings on the US App Store with an average of 4.85 out of 5; Google Play shows about 108,000 reviews averaging 4.7, with more than 5 million downloads. There is no Hong Kong listing, and therefore no Hong Kong rating.

Low ratings centre on the following: quality that appears to decline after several weeks of use, incorrect or fabricated answers, and destructive actions such as deleting large numbers of emails or damaging documents. Other users raise the breadth of permissions, suspended Meta accounts and repeated identity verification, assistants on different devices that do not share data, and inadequate screen-reader support. Users should approve each action with care and make backups before allowing edits.

Users for whom Muse is worth waiting: those with busy email and diaries, frequent online shoppers, and those who need an assistant to follow matters up, provided they are willing to let a Meta service access the relevant accounts. Once Muse launches in Hong Kong, the referral reward equals two weeks of heavy use.

Users who need not wait: those unwilling to connect email and accounts to Meta, those who need a tool that never acts on its own, and those who would use it only for general conversation; the free tier suffices and the referral tokens add little. For work use, the employer's rules should be checked before connecting company accounts.
