What is Muse?
Muse is a personal AI agent created by Meta that uses a web browser and connected apps to complete multi-step tasks such as filling out forms, booking travel, sending emails, and making purchases on behalf of users. You can set up Agent Analytics to see when Muse visits your website.

Why Is Muse Visiting My Website?
A user gave Muse a task that your site may help complete, such as researching a product, comparing options, or filling out a form. It likely reached your site through links or search results, much like a person would.
Should I Block Muse?
Usually not. Muse browses on behalf of a person trying to read, compare, or buy something on your site. Blocking it may prevent that person from completing the task and send them elsewhere. It does not affect traditional search rankings. For context, 7% of the top websites we track currently have robots.txt rules for Muse.

Frequently Asked Questions
What Traffic Patterns Should I Expect From Muse?
Muse operates a real browser, loading pages, running JavaScript, setting cookies, and navigating multi-step flows much like a person would. Because its route reflects the task it was given rather than a fixed crawl order, visits may look irregular. A session may pause while the agent processes a page, then continue somewhere unexpected.
Does Muse Follow Robots.txt Rules?
No. Muse is not expected to follow robots.txt rules, so a disallow rule only communicates your preference. Use Bad Bot Blocking to reject its requests, then use Agent Analytics to verify that they stop.
Is Muse Used for AI Model Training?
Not ordinarily. Muse is not categorized as an AI training scraper or data provider, so AI model training is not its expected purpose.
Does Blocking Muse Affect AI Search or Citations?
Blocking Muse can prevent people using the agent from accessing or acting on your website. It does not directly control whether your pages appear in an AI search index.
Does Muse Access Private Content?
Possibly, if a user grants access. Muse operates a real browser session, so when someone signs in through it, the agent can see anything available to that account. Without credentials, it can reach only what an anonymous visitor can.
How Can I Verify a Request From Muse?
Agent Analytics tracks Muse visits in real time. You can also check your server logs for requests whose user-agent string contains "Muse". Look for browser-like sessions that move through pages faster or more methodically than a typical person. Because Muse does not publish a verification method, any client can claim its identity and a log match is only a clue.
