Meta's Muse Connect 2026 update adds an inbox, Mac computer use and video calls
The Verge's Jay Peters reported the announcements as part of the Connect keynote. The keynote was scheduled for 4 p.m. PT (7 p.m. ET) and livestreamed via Meta.com. The Verge lists four developments. First, Muse agents get their own email addresses, which they can use to get tasks done and which you can use to talk to the agent. Second, the Mac app will gain the ability to "use your computer". Third, live video conversations with your Muse avatar are on the way, along with voice customization and a new model called Muse Realtime Avatar that controls how the avatar moves. Fourth, Muse is coming to Meta's smart glasses, where you'll be able to ask about what you're looking at.
Every one of these is described in the future tense: you "will" or "soon" be able to do them. The Verge didn't give rollout dates, supported regions or device requirements, so treat all four as announced plans, not features you can switch on today.
These are also additions to how Muse works, not replacements. The Verge notes that the main way to use Muse since launch has been a chat window. TechCrunch reported that Muse and its rival Instinct both added voice calling the week of September 18, so the expected order runs from chat, to voice, to live video.
Muse's growth explains how fast Meta is shipping
Muse is barely two weeks old. Meta introduced it on September 8, 2026, calling it a personal agent powered by a model named Muse Spark. Meta said it runs in a dedicated cloud virtual machine, Muse Secure VM, and launched it in the United States on iOS, Android and the web. Meta first introduced its AI agent, Muse, at the beginning of September 2026. Engadget's guide says the agent can browse the web, shop online, fill out forms, plan trips, send emails, schedule events and a whole lot more, and it can connect to third-party services like Google and Spotify.
TechCrunch reported on September 18 that a Mac app followed. It said the app can work with your files, messages, calendar, notes and mail inside their native macOS applications. According to TechCrunch, Meta says access is opt-in and the app asks for approval before sensitive actions. It quoted Mark Zuckerberg's post on X announcing the Mac app: "The team is shipping fast."
The Verge ties that pace to demand. It says Muse topped the App Store charts and was reportedly downloaded more than ChatGPT on mobile in its first 12 days. That comparison covers downloads only. It says nothing about active users, retention or whether people keep Muse connected to their accounts. Still, it explains why Meta is rolling out new ways to talk to the agent this soon after launch.
An @muse.ai inbox makes the agent something people can email
The email feature changes Muse's security model more than anything else in the announcement. Until now, email meant connecting an account you already have. In its launch material, Meta said users choose which apps Muse connects to and whether it can only read email or also send it. Meta said Muse asks for approval before sensitive actions such as sending a message and keeps an audit trail of what it has done and plans to do.
An address that belongs to the agent works the other way round. Other people could write to Muse directly instead of going through your inbox. The Verge's report doesn't give a domain, setup steps or rules for who can send to the agent.
RuntimeWire, a site that does reverse-engineering work, published more detail hours before the keynote. A static inspection of a Muse 2.2 installer supplied for review found a gated address-creation flow and a mailbox with Received and Sent views. It did not establish that the service is live or that Meta plans to announce it at Connect. The version inspected was Muse 2.2, build 1074644564 (production channel; statically inspected). According to RuntimeWire, addresses end in @muse.ai, and handles must be 3 to 32 lowercase letters, numbers or hyphens. The proposed sender name takes the form "Muse Personal Assistant (user name)". The client code also includes warnings for unverified senders and likely spam.
RuntimeWire's description of the feature is fair: a dedicated address would give that kind of assistant a direct channel for correspondence, instead of requiring every exchange to pass through its owner's existing inbox. The same design opens a way in. Meta's launch security write-up describes a separate Sentinel agent that controls network access and permissions, and defenses that label outside content as untrusted and screen it for prompt injection, where hidden instructions are planted in content an AI reads. RuntimeWire says Meta engineer Tarek Sheasha also described filters that keep one-time codes and password-reset links out of Muse's connected-email workflow. Meta hasn't said how any of those controls apply to mail sent straight to an agent's own address. Until it does, the right way to think about an @muse.ai mailbox is as a public inbox read by software that can take actions for you.
Computer use in the Muse Mac app moves the agent beyond its cloud VM
The second change is equally significant. Meta's launch engineering post describes the Muse Secure VM as an isolated Linux environment with its own browser, storage, CPU and memory. The agent uses it to do work, including compiling code and running subagents (smaller helper agents) at the same time. Meta also describes storing credentials so the agent never sees them. Engadget quotes Meta VP Vishal Shah saying Muse can "build its own software," so it's also able to handle more complex, multi-step tasks as well.
A cloud sandbox limits how much damage an agent can do: whatever goes wrong happens on Meta's machine, not yours. The Mac app already weakened that separation by reaching into native apps. The Verge's wording, that the app will be "getting the ability to use your computer", suggests broader control of the desktop. Meta hasn't said which actions that covers, how permissions will be granted or whether the cloud VM's protections carry over to local actions. "Use your computer" could mean anything from opening files to driving the whole interface, and the announcement doesn't narrow it down.
For WindowsForum readers, the practical point is simple: there is no documented Muse app for Windows. Meta lists iOS, Android, the web and now macOS. On a Windows PC today, Muse means the web client. Nothing Meta has announced says computer use will come to Windows, so the new capability applies to the Mac app only.
Muse Realtime Avatar gives the chat window a face and a voice
The video-call feature is easy to picture but easy to misread. "Video chat" here means a live conversation with an animated Muse avatar, not a call between two people. Muse already asks for this setup: according to Tom's Guide, when you first launch the app, Muse encourages you to design your own avatar and give it a personality. The Verge says you'll now be able to change how the avatar sounds as well as how it looks.
Meta Research published a post on September 23 titled "Bringing Your Muse to Life". It describes Muse Realtime Avatar as technology that turns Muse Realtime Voice, the existing voice system, into interactive avatars. Meta says the model can animate a character from reference media during a live conversation, with examples such as a portrait that shows facial expressions and an illustrated full-body character that gestures. Meta also cautions that these examples show what the model can do and don't necessarily reflect avatars available in the Muse app. So the research demos show what the model can do, not what you'll see on day one.
Meta hasn't said which Muse clients will support video calls, whether the Mac app or web client will get them first, or whether they'll launch outside the US.
Muse on smart glasses stays on a "coming months" schedule
The glasses announcement is the vaguest of the four. Meta's September 8 launch post already said Muse was "coming soon" to AI glasses. At Connect, according to The Verge, the timeline became "in the coming months", and the stated use is asking Muse about what you're looking at. Neither Meta nor The Verge named supported frames, a date or controls for visual input.
That missing detail matters given what was expected at Connect. Cybernews reported ahead of the keynote that new glasses were expected to come in two designs, without a camera but with an additional microphone for chatting with AI. Asking an agent about what you're seeing needs a camera, so Muse's visual features would presumably be limited to camera-equipped models. That's our inference; Meta hasn't said which frames will support Muse.
What this means for Windows and Mac users weighing Muse
If you already use Muse, you don't need to do anything today, because none of the announced features has a date. The real decision comes when the agent inbox or the Mac computer-use update actually appears. If you're a Windows user, the Mac-only computer-use feature won't reach your machine at all. Your exposure is limited to the web client and the accounts you connect to it.
The settings you already have are the ones to check now. Engadget says you can opt out of model training by going to Muse's settings, scrolling down to "data controls" and deselecting "help improve our AI models." The same guide points to a "permissions" tab in settings for changing what the agent can access. Meta also says you can disconnect services and ask Muse to forget things it has learned. According to Carly, a productivity-software vendor, Muse is US-only and 18-plus at launch, and it runs on one person's own accounts. Muse is built for personal accounts, so IT teams shouldn't treat it as an approved tool for corporate mailboxes.
- Treat the email addresses, Mac computer use, video calls and glasses support as announced plans until Meta gives release dates. The Verge's report didn't include any.
- If you connect a work account to Muse, remember it runs on one person's own accounts and Meta has published nothing on managing it for organizations.
- Wait for Meta to explain how mail sent to a Muse agent's own address is filtered and approved before giving that address out.
- On a Mac, check which apps and data the Muse app can reach now, before a broader computer-use update arrives.
- On Windows, Muse is available through the web client, and nothing Meta has announced brings computer use to Windows.
- Opt out of model training under the data controls setting if you don't want your Muse conversations used to improve Meta's AI.
Meta wants Muse to be something you talk to rather than an app you open: by email, by video and eventually through glasses. The avatar will get the attention, but the email and computer-use changes carry the real risk. An inbox anyone can write to and an agent that can operate your Mac both need clearer permission rules than Meta has published so far. When Meta sets release dates for the @muse.ai mailbox and the Mac update, the documentation that comes with them should be the basis for deciding whether to turn them on.
