Mark Zuckerberg presented Muse Charm at Meta Connect on Sept. 23, 2026, while Meta’s terms prohibited anyone under 18 from using Muse. Jolly, the AI agent’s plush-looking mascot, has also prompted concern about its potential appeal to young children. Meta’s reported plan was to sell a Tamagotchi-style device for the Muse character later in 2026.
Muse’s terms set an adult age limit
Meta’s supplemental terms, updated Sept. 8, 2026, prohibit people under 18 from using Muse. A higher minimum age applies if required in the user’s country or territory.
Meta says Muse asks users for their date of birth, blocks people it detects may be under 18 from creating accounts, and applies additional checks to help confirm that users who say they are adults are over 18.
Why Jolly’s design has drawn concern
Jolly is a customizable, plush-looking character associated with Muse. A youth advocate argued that its appearance could appeal to very young children. Marketing and technology scholars have also argued that cute design can make an AI product feel warmer and less threatening, or lead users to be less guarded.
Those concerns center on the character’s possible appeal and the impression its design may create. Meta’s terms, meanwhile, set an adult-only eligibility rule for the service.
What Muse’s terms say about data and oversight
Meta’s terms allow it to use content in Muse interactions to improve AI at Meta. Users can opt out in settings under Data Controls.
The terms also place responsibility for users’ instructions and the resulting actions on the users, and call for meaningful human oversight. For state-changing actions, such as financial transactions, they advise review or approval beforehand.
Separately, Meta describes Muse’s security setup as including an isolated cloud virtual machine, a permission authority called Sentinel, and approval flows for actions that require user approval. Meta also acknowledges that Muse can make mistakes.
