Your site, as a machine reads it
Read the document an AI crawler actually receives from your page — the words it can quote, and where it gets nothing. No account, nothing stored.
What does it check?
The document a plain fetch returns — the words an agent can actually quote, and where it got nothing. Then who robots.txt lets in, what the site publishes for machines (llms.txt, sitemaps, agent doors), and which of your surfaces elsewhere an agent can reach.
Why not just look at my site?
Your browser runs JavaScript and looks at images. Most agents do neither: they take the HTML as served. Anything your page says only after scripts run, or only inside a picture, is not there to be quoted — and you cannot see that by looking.
Is this SEO? Is it AEO?
Neither, and there is no score. SEO is about ranking and AEO is about being mentioned — both ask whether you show up. This asks something earlier: what an agent can actually read on your page. Everything it goes on to say about you is built out of that, and nothing else.
What happens to the address I type?
One page is fetched, once, and nothing is stored. No account, no cookie, no record of what you looked at.
