Meta's Muse offers better weekly summaries in exchange for a live bank connection
Sensor Tower counted more than 900,000 downloads of Meta's Muse in its first week. Wired's reviewer found an agent that browses competently while its ideas tab keeps pitching a live link to the bank.

What happened
- Meta's Muse, an AI agent that takes task requests by chat and works in the background, was downloaded more than 900,000 times in its first week, according to Sensor Tower.
- The app is free, and Wired's reviewer found it connects easily to outside data sources including their email and bank account.
- After the reviewer mentioned saving for a vacation, the app offered to wire its savings tracker to their real balance if they linked checking and savings accounts.

Why it matters
- exposure Because Muse also runs inside WhatsApp, the assistant asking for inbox and bank connections is reachable on phones no administrator provisioned or approved.
- constraint Without an off switch, the strongest control a user has over the memory file is asking the system that holds the data to delete it.
- decision Product teams shipping their own assistants now have to justify each connector prompt against what it changes in the task at hand, since users are being taught to expect the ask.
- contradiction The only public evidence on whether Muse collects more than it completes is one reviewer's few days of use, and Meta disputes it, so nobody outside the company has a measured completion rate to weigh against the data asks.
Downloads are not connected accounts. Sensor Tower's figure, more than 900,000 in seven days, works out to roughly 128,000 a day, and what it measures is distribution through apps Meta already owns: prime placement on Instagram, onboarding and integrations through WhatsApp and Messenger [1][21][23]. The number who linked an inbox or a bank feed is missing from Wired's review [22]. It does report that the app's "ideas" tab kept prompting the reviewer to connect more information [11].
Asked to order breakfast from a San Francisco bakery called Kahnfections, Muse drove a virtual machine to the site and added a biscuit sandwich with garlic aioli, cheddar, egg and bacon to the cart [5][7]. Its summary before final approval read: "One tweak the site forced: cheese is single-select, so I picked cheddar and left a note asking them to add Swiss too if they can" [8]. It asked for a credit card through Stripe to complete the purchase, and selected the "no tip" option [9]. The task work is genuine. Wired's reviewer says Muse rarely gets lost while browsing, which was not the case with similar tools tested last year, including the now-defunct ChatGPT Agent [6].
The data asks are a separate product: the day after the reviewer said they wanted help saving money for a fancy vacation, Muse offered to "wire your savings tracker to your real balance" if they linked their checking and savings accounts [12]. It named the payoff: "Then the weekly summaries and drift alerts work off real numbers instead of hand-entered estimates" [13]. That connection upgrades a recurring report about the user.
The memory file sits behind the avatar at the top of the screen, described in the app as "Your curated long-term memory: durable facts, preferences, and commitments" [14]. Users can send a chat request to wipe it, or edit the file by hand. Meta does not currently offer a toggle to turn the memory feature off [15].
"Folks don't recognize that when you talk to an AI, you are talking to the company hosting the AI," Rory Mir, director of open access at the Electronic Frontier Foundation, told Wired [18]. Meta spokesperson Emil Vazquez said "Muse is the first personal AI agent built for everyone, with built-in protections and user controls that put people absolutely in charge of how they use it" [17].
Two tests sort connector prompts in your own product. The first is whether the data changes something the user sees in the task in front of them, or only improves a summary they will get later. The second is whether the task still completes if the connector is removed. Data that passes the first belongs in the task flow, shown next to the output it changed; data that only feeds the later summary belongs in settings, behind a toggle the user can flip themselves [15].
What to watch
- Whether Meta ships a memory off switch alongside the existing wipe-by-chat request and hand-editable file.
- Sensor Tower's week-two and week-four download figures, and any number Meta publishes for accounts actually connected.
- Any disclosure from Meta about how connected inbox and bank data are used outside the task the user requested.
