Is Meta Muse good for productivity and to-dos?

What did Meta actually say about Muse's 10 million users?

On its third-quarter 2026 earnings call, Meta said more than 10 million people have set up a Muse personal agent, and that shopping and personal productivity are what they use it for most. That's a big number for an app that only launched on September 8, and almost all of it comes from the US and Canada. Meta also said about a quarter of people who've set up Muse use it on any given day. That daily figure tells you more than the headline does. Downloads measure curiosity. Daily use measures whether something has become part of someone's routine. One in four is solid for a brand-new agent, but it also means most people who signed up don't open it every day.

Shopping is the clear leader. More than a quarter of people using Muse shop with it, and Meta says the average purchase is over $200. That was big enough that in the first week the company had to work with its payment partner to raise credit limits. Productivity came second, mostly through connectors that link Muse to your email and calendar. Meta plans to keep Muse free for most people and take a cut of the commerce that runs through it, with paid tiers for power users who want more advanced models or more usage. That business model matters. An assistant that earns a percentage of what you buy has every reason to get good at buying things first and at everything else second.

Which brings us to the question most of you actually care about. If personal productivity is Muse's second-biggest job, it's competing directly with tools built for nothing else: reminders that fire, to-dos that don't vanish, follow-ups that happen without you chasing them. If you run a small business, a team or a household out of WhatsApp, the test isn't whether Muse can fill a cart or book a dinner table. The test is whether it can handle 'Remind me to call the accountant every Monday at 9', a list of supplier follow-ups and a noisy group chat, week after week, without you babysitting it. The rest of this piece checks exactly that, with real messages.

Is Meta Muse good for reminders and to-do lists?

Yes, Muse handles personal reminders well. Its help pages show it supports one-time reminders at a set date and time, location-based reminders that go off when you're near a place, and recurring tasks on a daily, weekly or custom schedule. Reminders arrive as messages in your Muse conversation, timed to your own time zone, and you can ask what's scheduled, move a time, reword a reminder or delete it. The app also has an Upcoming tab that lists everything in one place. Meta's own example is 'Every Monday at 9am, remind me to submit my timesheet', so the team clearly thought about weekly admin. Reminders weren't bolted on at the last minute.

To-do lists are less clearly defined. Muse can create documents such as spreadsheets and PDFs, so you can keep a running list in conversation or ask it to put your tasks into a spreadsheet. What Meta doesn't present is a dedicated task manager with due dates, priorities and shared lists you can hand to someone else. That's less a flaw than a choice. Muse is pitched as an agent that gets things done for you: it sends emails, books travel, fills in forms and checks out a cart. The to-do list is mostly a by-product of that. If you want a list your business partner can also add to, or one your whole team can see, you'll hit the limits quickly.

The bigger catch is whether you can use it at all. Muse is officially available only to adults in the US and Canada, and Meta hasn't named the next countries or given a date. Meta checks the country tied to your account, so switching phone numbers won't get you in, and it may break the terms of service. For a lot of our readers in Israel, Europe and Latin America, that settles the question before features even come up. If you're stuck on a 'not available in your country' screen, there's a WhatsApp assistant you can use today without waiting for Meta's rollout. If you're in North America, Muse's reminders are genuinely decent and worth trying.

Where does Muse fall short if your day runs in WhatsApp?

Muse falls short on the work that involves other people. It does run inside WhatsApp, so you can message it in a chat like any contact, but it's built around you and your own accounts: your email, your calendar, your shopping cart. Meta's materials describe one-to-one chats with Muse. They don't show it sitting in a WhatsApp group, recapping the conversation you missed or reminding the whole team about Friday's timesheets. A solo user might never notice. A team lead with a standup group, a landlord with a building chat or a coach with a parents' group will, because the group is where most of their admin actually happens. That's the gap that hurts most.

The second gap is follow-ups. Once you approve them, Muse can send outgoing messages like emails, which is useful. But most small-business follow-ups aren't emails. They're 'Did you send the quote yet?' to a supplier on WhatsApp, or 'Can you confirm Thursday?' to a client who only answers in voice notes. You don't want to draft that message yourself. You want to hand it off and hear back with the answer. My honest view: reminders are a solved problem. Every assistant out there can ping you at 9am. What eats your week is chasing other people for answers, and that's where a shopping-first agent has the least to offer.

Then there's the cost of one more app. Muse works on the web, on phones, on the Mac and in WhatsApp, but the full experience, from the Upcoming tab to the settings and connectors, leans on its own app and account. That's fine if you like apps. Plenty of people don't. If your phone already holds a half-used to-do app, a calendar you forget to check and a notes app full of half-finished thoughts, a fifth tool rarely fixes things. We've looked separately at whether Muse is worth downloading for WhatsApp-heavy users, and the pattern holds. Muse shines when you want an agent to take on a big task, and it's weaker when you just want small daily admin to stop slipping.

Meta Muse vs a WhatsApp AI assistant: which fits your admin?

Pick Muse if you're in the US or Canada and want an agent that shops, books and runs errands across your accounts. Pick a WhatsApp-native assistant if your admin is mostly reminders, lists, documents and other people. That's the short version. The longer version comes down to where your day happens. Muse's strengths, like checkout, travel booking, form-filling and email and calendar connectors, are about handling big one-off jobs for you. Agent Sonic is built for the opposite rhythm: dozens of small things a week, each one a quick WhatsApp message. 'Remind me to call the accountant every Monday at 9.' 'What did I say the plumber quoted?' 'Summarize this lease and flag the notice period.' None of those needs a new app.

Group admin is where the gap is widest. Add Sonic to a WhatsApp group and it can post a catch-up recap for anyone who missed fifty messages, run a quick poll, keep a shared shopping or packing list, split expenses and send automatic reminders to the whole group. A youth football coach can set 'Every Thursday at 6pm, remind the group that practice starts at 7' and stop messaging parents one by one. A team lead can have timesheet reminders land in the team chat every Friday afternoon. In theory you could copy some of that with Muse by setting personal reminders and pasting them into the group yourself. But then you're the assistant, not the software, and that's the very job you wanted to get rid of.

Documents and calendars are closer to a tie. Both tools can summarize documents, and both connect to calendars. Sonic reads PDFs, contracts, invoices and spreadsheets you forward into the chat, and it works with Google Calendar, Sheets and Docs, plus a read-only Notion knowledge base. Send 'Add a meeting with Noa on Tuesday at 3 to my calendar' and it's done. Forward an invoice and ask 'What's the total and when is it due?' and you get a straight answer. Sonic also keeps a persistent memory of your preferences and notes, so you're not explaining who your accountant is every week. Muse wins on commerce and email. Sonic wins on the WhatsApp thread you already have open.

How do you move your to-dos and follow-ups into WhatsApp?

Start with the three things that slip most often: recurring reminders, loose to-dos and follow-ups with other people. You don't need a migration plan. Open a chat with Sonic and send whatever's in your head, in plain words: 'Every Monday at 9, remind me to call the accountant.' 'Remind me on the 28th to pay the studio rent.' 'Add get the van serviced to my list.' Voice notes work too, which helps when you're driving between jobs or standing in a supplier's warehouse with your hands full. Ask 'What's on my list?' whenever you like and the answer comes back in the chat. There's no dashboard to set up, so your first reminder takes about as long as typing the sentence.

Follow-ups are where you'll notice the biggest difference. On the Pro plan, Sonic's outreach tasks, which are in Beta and may be paused from time to time, let you say 'Ask Dana when the invoice will be ready and let me know.' Before anything is sent, Sonic shows you the exact first message, and you reply 'yes', 'no' or something like 'friendlier, no emoji'. It then writes to Dana from Sonic's own number, introduces itself as your assistant, follows up at most once if the answer is vague, and reports back. The limits are tight on purpose: one task at a time, up to three people a day, first messages only between 08:00 and 21:00 in their time zone, and one-to-one chats only. The step-by-step outreach tutorial walks you through it.

If you're in North America and already like Muse, you don't have to pick a side. Use Muse for the shopping and travel jobs it was built for, and keep your daily admin where your clients, suppliers and groups already are. If you're outside the US and Canada, or you'd just rather have one chat than another app, the decision is even simpler. It's still worth watching Meta's roadmap, because the newer Muse Wonder models and wider rollouts could change parts of this comparison. For now, get access to Agent Sonic by leaving your details. You'll get Sonic's number and a short onboarding, and you can set your first reminder a minute later.
