Meta has finally shipped the product Mark Zuckerberg has been talking about in every interview for the past year: Muse, a personal AI agent that doesn't just answer your questions but actually does your work — sending emails, booking travel, filling forms, tracking subscriptions, and nudging you toward your goals while you sleep. We wrote about Muse's rocky road last week; now the app is real, live on iPhones, Android and — as of September 17 — the Mac. Let's dig into what it does, what it costs, and when India gets it.
01.An agent, not another chatbot
The distinction matters. ChatGPT answers; Muse acts. You tell it what needs doing — "book a dentist appointment", "find me a cheaper flight to Delhi", "plan my week" — and it opens a browser, fills out forms, drafts the email, and asks for your approval before sending. For longer tasks, it keeps working in the background after you close the app, and comes back to you when something changes.
It's powered by Meta's own Muse Spark family of models, built specifically for this kind of real-world agentic work. Meta's pitch is that anyone can use it out of the box — no prompting skills, no technical setup. You can even customise your agent's name and avatar. Meta AI chief Alexandr Wang named his own agent after his dog, Euler, and calls it "a second brain." And it remembers: tell it once that your friend is vegetarian, and it remembers before sending party invites. That memory is what makes the privacy questions sharp.
02.iPhone, Android, Mac — and WhatsApp
Muse launched in the US on September 8 across iOS, Android and the web at muse.ai. This week, Zuckerberg announced the Mac app, which "works across apps, files, calendar, notes, and messages on your computer" with you controlling what it can access. There's also a Muse chat built directly into WhatsApp — though that lighter version skips some app features like the personalized feed.
The app is organised into five tabs: Chat, Feed, Ideas, Goals — and Artifacts, where you describe a tool you wish existed and Muse builds it for you in minutes.
03.The security architecture is genuinely interesting
Meta knows it's asking for a level of trust it hasn't exactly earned, so the technical design is worth understanding. Muse doesn't run on your phone — it runs on a dedicated cloud computer called the Muse Secure VM, with its own isolated browser. A separate watchdog AI, called Sentinel, runs on the same machine and nothing Muse does reaches the internet without Sentinel's approval — and often, without yours.
Muse never sees your passwords or payment details; credentials go into secure storage it can use but not view. You get a complete audit trail of everything it has done and plans to do, and you choose exactly which apps it connects to and how much access each gets. You can tell it to forget things, and you can opt out of your conversations being used to train Meta's models. Meta also says Muse data never touches its ad systems, and a fully encrypted "confidential" version of the VM — which even Meta can't access — is promised later this year.
04.What it costs — and the shopping angle
Pricing is simple: free for most everyday use, with weekly usage limits. Two paid tiers unlock more — Power at $20/month (about ₹1,750) and Maximum at $100/month (about ₹8,750) — and Meta warns you before you cross into paid territory.
The most futuristic bit is payments. Muse can complete purchases using Link by Stripe, which generates a one-time-use card so your real card details never surface. Muse is also the first AI agent covered by Link's purchase protections — damaged items, price drops, and return guarantees on eligible purchases. Shop Pay and 1Password are on the way.
Solving "how an AI agent safely pays for things" is a big deal — it's the piece that makes agents genuinely useful versus demo-cute. If you want to understand how these agent systems work under the hood, our GPT-6 Astra — Zero to Hero Guide has full chapters on AI agents and computer use that map directly onto what Muse is doing here.
05.So when does Muse come to India?
Here's the honest answer: nobody knows, and Meta isn't saying. The rollout is US-only for users 18 and above, with "more countries being added over time." But think about the logic for a second. Muse already lives inside WhatsApp — an app with over 500 million Indian users. Meta's whole strategy is billions of people, not millions of American early adopters. An India launch with UPI-based payments feels less like speculation and more like inevitability. That's a guess, to be clear — but it's an educated one.

06.Should you trust Meta with your inbox?
The elephant in the room: Muse launched less than two weeks after Meta agreed to pay up to $18 billion in settlements over claims it designed Instagram and Facebook to be compulsive for young users. Now the same company is asking for your email, calendar, and payment flows. TechCrunch asked bluntly whether consumers will trust it; Meta's answer is the security architecture above, plus Wang's point that "Muse is constantly checking in with you before it does anything sensitive or important."
The scepticism is fair. But the counterpoint is also real: the architecture — isolated VM, a separate Sentinel agent, hidden credentials, opt-outs — is more thoughtful than most competitors have shipped. Competition helps too. Apple's new Siri AI arrived the same month, and OpenAI, Anthropic and others are racing in the same direction. Whoever earns the trust first wins the biggest prize in consumer tech.

What This Means for You
For most of us in India, Muse is a preview of how we'll all be living within a couple of years — delegating the boring half of our digital lives to an agent. You don't have to wait passively. The same agent skills that make Muse tick — good prompting, understanding how agents plan and use tools, knowing what to delegate and what to double-check — are learnable today, and the GPT-6 Astra — Zero to Hero Guide walks you through them step by step, from your first prompt to your first working agent. The people who learn to direct agents well before Muse reaches India will hit the ground running the day it does.
