Meta launches Muse AI agent in Japan, from 月2,799円

Muse is positioned as an agent rather than a chatbot: instead of answering only when asked, it runs tasks in the cloud and keeps a feed of information matched to what the user has shown interest in. That design shows up in the examples Meta gives, such as compiling candidate products into a table, drafting a detailed travel plan, or reading Gmail and Google Calendar to surface tasks.

The fitness example goes further. Given a current weight, height, and a goal of losing 2kg in a month, Muse proposed a training plan and a schedule that notifies the user on training days, then added an animation explaining exercises and a timer so the program can be followed in order. Outputs like these are saved automatically as artifacts, which the user can reopen whenever needed.

The service is available in Japan and uses existing Meta accounts for login, with a free weekly token allowance and paid upgrades from 月2,799円. An invite-code offer of 10億トークン is also in place as of 2026年10月.
