Whether Muse's free plan is enough depends first on your usage meter, not on the price list. The free plan has a usage limit, and Meta has not published exactly how big it is. Power costs $20 a month for 500 million Muse tokens a week; Maximum costs $100 a month for 3 billion a week. A token is not a message, and Meta has not published a conversion from tokens into tasks, so do not map it onto "a few chats a day."
Do it this way: 1. Use the free plan for one or two weeks doing the things you actually want handled: sorting email, scheduling, comparing prices, and ordering. 2. Open the usage meter in Settings and see how far you are from the limit and whether it warns you that you are about to hit it. 3. Only when you keep hitting the limit several days in a row and tasks stall should you consider Power. Maximum is for people who have the agent working for long stretches every day.
One more thing that is easy to mix up: the Muse subscription and billing for Muse Code or the Model API are separate bills. Do not carry the terminal coding tool's plan prices over to the personal agent; what counts is what is written on each product's own subscription page.
Check two bills before upgrading
The first bill is money: billing renews monthly, and there is no annual price. If you bought in the App Store or Google Play, you cancel there, not inside the app. The second bill is the card: at sign-up, the app may ask you to link a payment card. Meta's explanation is that real actions such as shopping need one, and the free tier may run into it too; go by what the sign-up page actually shows. Before linking, make sure the card's limit and billing alerts are on. The allowance follows the account: changing devices or accounts does not carry it over.
In short: run the free plan first and let the usage meter decide. Power is for people who use it every day; Maximum is for heavy, ongoing agent work. If you upgrade and find you are not using it up, dropping back to the free plan costs nothing to be embarrassed about: the allowance is counted weekly and starts over the next week. If the meter barely moves, your usage never reaches the paid line at all — save the money.
