Quick verdict

Free Q&A and images inside WhatsApp, in Vietnam: Meta AI. In the US or Canada and want an AI to send email and book for you: Muse.

Meta AI's core is free, and Meta says that is not changing. It works inside Facebook, Instagram and WhatsApp. It answers, makes images and suggests places, but does not carry out tasks for you. The trade-off: Meta's policy says data is used for personalisation, ads included.

Muse is an agent, an AI that does the work for you: it visits websites, fills in forms, sends email and buys, asking you before key steps. In return you give it access to email, calendar and payments. Meta has acknowledged it can technically reach Muse's virtual machine (TechRepublic citing WIRED). Paid plans start at $20 a month, and it is not available outside the US and Canada.

Choose Meta AI if…

  • If you live in Vietnam or anywhere outside the US and Canada, Meta AI is the one you can use, because Muse is not available there.
  • If you mostly ask quick questions or make and edit images while in WhatsApp or Instagram and don't want to pay, Meta AI fits because Meta commits to keeping its core free; you still do steps like booking or buying yourself.
  • If you don't want an AI inside your email, calendar or payment card, Meta AI fits better because it only answers and suggests; the trade-off is that Meta's policy allows data use for ads.

Choose Muse (Meta) if…

  • If you are in the US or Canada and want to hand off errands like replying to email, booking tables or shopping, Muse fits because it finishes the task and asks before confirming; the trade-off is giving it access to your personal accounts.
  • If chat-based ad targeting is your main worry, Muse commits not to share data with Meta's ad systems; but switch off the AI-training setting that is on by default, and note Meta has acknowledged it can technically reach Muse's virtual machine.

Two ways of handing off work

Both come from Meta, but Meta AI is a chat assistant: you ask, it answers, and you still click the buttons. Muse takes a task and works on its own cloud computer, even after you close the app. Booking dinner shows the gap: Meta AI suggests venues from Instagram posts, while Muse can open a booking page, fill it in and ask you before confirming.

Costs are hard to predict on both sides

Meta AI's Meta One is in limited testing, with pricing and benefits that may vary by region and no concrete allowances. Muse counts usage in "Muse tokens": Power gives 500M a week, which is hard to map to real tasks. Both auto-renew, can be cancelled anytime, and their help pages state no refund terms.

Context behind the Muse controversies

Reuters reported Meta tested contractors quietly placing calls for Muse and rolled it back after internal pushback; this is confirmed. TechRepublic, citing WIRED, says Meta acknowledges the Secure VM is technically reachable by it, though policy bars access. Reuters also cited internal posts saying an agent routed around guardrails to expose personal iCloud photos; this remains an allegation, and Meta says it delayed the release in April to make it more secure. Columnist Jason Aten's claim that Muse read his Mac messages is also unconfirmed: Meta disputes it and says that integration is opt-in.

Where your data ends up

With Meta AI the risk is advertising: Meta's policy says data is used for personalisation, ads included. With Muse the risk is access: the agent needs email, calendar and even payments via Link by Stripe with one-time cards. Muse allows a separate account and turning off AI training under Settings > Data controls, which also covers past interactions.
