You are most likely here because you found this agent in your server logs. Here is what it does, where it comes from, and how to stop it.

| Why it visited | Someone entered a URL into one of our free assessments and asked for a result. This is a request a person made, not a crawl. It does not run on a schedule, and it does not follow links to other pages. |
| What it requests | The single page it was given, plus robots.txt, llms.txt and sitemap.xml. The brand check also fetches the stylesheets that page links, because a brand lives in CSS the page itself does not contain. So a readability check is about four requests; a brand check is typically four to twenty, one per stylesheet. It submits no forms, uses no credentials, follows no links to other pages, and writes nothing. |
| Where it comes from | Datacenter addresses in the US East region. We do not publish a fixed IP list, so match on the agent string rather than on addresses. |
| How often | Only when somebody runs a check, and rate limited per visitor and per target domain. |
| Training data | No. Pages fetched by this agent are never used to train a model. The text is read once to produce one report, and stored as the record of that report. |
Well-behaved agents separate a page a person asked for from an automated crawl, so a site owner can allow one and refuse the other. We do the same.
| IMC-Audit-User | A person asked for a check on this page, just now. Version 1.0. This is the agent you are seeing. |
| IMC-AuditBot | Reserved for scheduled monitoring of sites whose owners have hired us. It is not in service yet. When it is, it will honor robots.txt. |
Add this to your robots.txt. We stop, and anyone who runs a check on your domain is told the page could not be read as a machine.

If you would rather it stopped right now, or you think it behaved badly, write to info@infinitusmc.com and we will handle it by hand. That is a person, not a queue.
Run the check yourself at /ai-readability. Built by Infinitus.
