TL;DR: Both are Meta products, but they are not the same kind of thing. Meta AI is a free chatbot inside WhatsApp, Instagram, Messenger and Facebook that answers questions where you already chat. Muse is Meta’s personal AI agent: it connects to your email, calendar and apps and does multi-step jobs for you — booking, buying, planning, forms — in the background. Want answers? Meta AI. Want tasks off your plate? Muse.
Bottom line: Meta AI talks. Muse acts. Pick based on which of those you actually need.
What are Muse and Meta AI, in one paragraph each?
Meta AI is the assistant built into Meta’s social apps, also available at meta.ai and in a standalone app. Powered by Meta’s Llama model family, it answers questions with live web search, generates images inside chats, and works with voice in WhatsApp. For consumers it is entirely free.
Muse — Meta’s personal AI agent, reviewed in full in our Muse review — is a separate product built to execute. Give it a goal and it plans the steps, connects to services you authorise, and keeps working after you close the app, inside a dedicated secure virtual machine. Sensitive steps, like sending an email or paying, pause for your approval. It launched in the US on web, iOS, Android and WhatsApp.

Pricing and limits checked October 2026 from Meta’s launch reporting and help pages. Muse’s paid tiers are new and its help pages describe availability as limited testing in the US, so expect details to move. Meta has also launched separate Meta One bundles that raise limits on heavy generative features across its apps; the core Meta AI assistant remains free.
The difference that matters: answers vs actions
Ask Meta AI to plan a trip and you get a good itinerary in the chat — then you open five more apps to book it. Ask Muse to plan the same trip and, once you have connected the relevant accounts, it works through the steps itself and brings the booking back for a yes before money moves. That agent loop is the entire product — and the entire risk: an agent that can act needs permissions a chatbot never asks for, which is why Muse runs in an isolated secure machine and why starting with one low-stakes connection is the sensible first move.
What does each one cost in practice?
For most people, both cost nothing. Meta AI is free, full stop. Muse is free up to a weekly allowance Meta described at launch as 100 million tokens — generous enough that Meta expects most people to stay free. Power ($20/month) raises it to 500 million tokens a week; Maximum ($100/month) to 3 billion. One friction: Muse’s signup asks for a payment card even on the free tier. Meta AI never asks — it is already inside apps you have.
Which should you use?
Use Meta AI if you want quick answers, ideas, drafts and images inside the apps you already live in, and you are happy doing the follow-through yourself. For casual questions it is the most frictionless AI on earth — no new app, no account setup, no bill.
Use Muse if your problem is not information but errands: the inbox triage, the booking, the form, the plan that needs ten small steps across four apps. That is work a chatbot can only describe and an agent can actually finish.
Use both, the way Meta intends: Meta AI for questions in your chats, Muse for jobs you would otherwise put on a to-do list. They are complements, not rivals.
Frequently asked questions
Is Muse the same as Meta AI?
No. Meta AI is the free chatbot inside Meta’s apps and meta.ai. Muse is a separate agent product that connects to your apps and carries out multi-step tasks in the background.
How much does Muse cost?
Muse is free with a weekly usage allowance — described at launch as up to 100 million tokens per week. Power costs $20/month for 500 million tokens per week, and Maximum costs $100/month for 3 billion tokens per week.
Is Meta AI really free?
Yes. The core assistant is free across Meta’s apps and the standalone app. Separate Meta One bundles raise limits on heavy generative features, but everyday chatting stays free.
Can Meta AI book things or send emails for me?
No — Meta AI can draft, suggest and plan, but it does not execute tasks in your other apps. Acting on your behalf — sending the email, making the booking, completing the purchase with your approval — is what Muse was built to do.
