Meta has launched Muse, a personal AI agent that completes tasks for you instead of just answering questions. It went live in the United States on 8 September 2026 for adults aged 18 and over.
In its launch announcement, Meta puts it simply: “It doesn’t just answer questions, it actually does the work.” Here is what the Meta Muse AI agent does, what it costs, how Meta says it protects your data, and what we know about an Irish and wider European launch.
What is Meta Muse?
A chatbot helps you write an email. An agent writes it, sends it and follows up. That is the shift Muse represents.
Muse runs on Muse Spark, a model family from Meta Superintelligence Labs, the unit led by chief AI officer Alexandr Wang. Meta first released Muse Spark in April 2026.
The launch is central to Mark Zuckerberg’s plan to give everyone a personal agent. He set out that vision in a 6,500-word essay in August. On Meta’s July earnings call, he told investors that personal agents would be the base for Meta’s next products and revenue lines. TechCrunch called Muse the company’s biggest consumer AI bet so far.
What the Meta Muse AI agent can do
Everyday tasks
According to Meta, Muse can:
Send emails and party invitations
Book travel and appointments
Fill out online forms
Negotiate and work to lower bills
Turn recipe reels into grocery lists
Monitor home security camera feeds
Build documents, PDFs, spending trackers and simple web pages
Buy things online
Purchases go through Link by Stripe, which comes with purchase protections. Meta says Shop Pay and 1Password support are coming soon.
Connected apps
Users choose which apps to connect, one at a time. Categories include email, calendars, payments, health and fitness, smart home, dining, shopping, music and events. Wang named services such as Gmail, Outlook, Google Calendar, OpenTable, Spotify, Peloton and Withings.
If a service has a public API, Muse can connect using login details the user provides. If there is no API, Muse uses a web browser instead.
Always working
Muse keeps working after you close the app. Each user gets a dedicated computer in Meta’s cloud, with a built-in browser the user can watch.
Meta says Muse works on a schedule and responds to events as they happen. It only messages you when something is new or needs your input. You can also turn these proactive messages up or down.
Muse remembers context across conversations, and users can read and edit that memory. A Goals tab tracks longer projects and the plan to reach them. Users can also name their Muse and give it an avatar.
In a design blog, Meta shared the first line of Muse’s system prompt: “Your purpose is to make your user’s life better.”
How Muse was built
Muse was reportedly developed under the internal codename Hatch. The Information reported that Meta was building an agent inspired by OpenClaw, an open-source agent popular with tech enthusiasts. The goal was a version simple enough for people who are not technical. In early September, reports said the Hatch project would carry the Muse name.
Muse is available:
- On the web at muse.ai
- Through iOS and Android apps
- Inside WhatsApp
Meta says support for its AI glasses is coming.
Meta Muse pricing
Muse is free to start, but a payment card is needed at sign-up. An in-app meter shows how much usage is left and warns users when free usage runs out.
| Plan | Price (USD) | What you get |
|---|---|---|
| Free | $0 | Base usage |
| Power | $20 a month | More usage |
| Maximum | $100 a month | The most usage |
Wang told Axios that most people should be able to do what they need on the free tier. The paid plans help Meta cover computing costs. There are no ads inside Muse, but Meta is exploring commerce as a future revenue source.
Privacy and security
To work well, Muse needs deep access to email, payments and health apps. TechCrunch framed the launch as a test of whether people still trust Meta with their data.
How Meta says it protects users
Meta explains its approach in a detailed security post:
- Muse Secure VM: Each user’s Muse lives on its own isolated computer in Meta’s cloud. Connected data and login details are stored there.
- Sentinel: A second agent runs on the same machine but is kept apart from Muse. Every action that reaches the outside world passes through Sentinel, and Muse cannot override it.
- Approvals: For hard-to-undo actions, such as emailing someone or making a purchase, Muse stops and asks the user first. Users can make these settings stricter or looser.
- Hidden credentials: Meta says Muse never sees passwords or payment details.
- No ads link: Meta says Muse conversations and data are not shared with its ads systems.
- Bug bounty: Meta opened a public bug bounty paying up to $300,000. That includes up to $130,000 for a successful prompt injection attack on a single user. (Prompt injection means hiding instructions in content to trick an agent.)
Early reactions
- Tobi Lütke, Shopify CEO, posted on X: “You should try Meta’s Muse app. It’s pretty amazing.”
- Garry Tan, Y Combinator CEO, praised the underlying technology after early testing.
- Investors: Meta shares rose about 6% the day after launch. Analysts at TD Cowen said Muse could grow into a meaningful revenue source over time, though they are not forecasting near-term revenue from it.
When will Muse reach Ireland and Europe?
Meta have not yet announced a date for an Irish and European release. Muse is US-only for now, and Meta’s launch materials do not give a timeline for other countries.
Ireland will have a key role when it does arrive. Meta’s European headquarters is in Dublin, so Ireland’s Data Protection Commission (DPC) is its lead privacy regulator across the EU.
Past launches show how this can play out:
- AI training: In 2024, Meta paused plans to train its AI on public posts from European users after the DPC raised concerns. Meta went ahead in 2025 after making changes.
- WhatsApp ads: The DPC made recommendations before ads launched here. In May, Silicon Republic reported that the delayed Irish rollout would go ahead after the DPC was satisfied with Meta’s changes.
Muse connects to health apps, payment accounts and private messages. Health data gets extra protection under GDPR. Meta has not said whether Muse will need changes to launch in the EU.
