AI visibility checker: what assistants see on your site
ChatGPT, Claude, Perplexity and Google's AI answers read your site with machines, not eyes. Enter your address and see exactly what they find — and what is missing before they can recommend you.
We fetch a few public files from your site and analyse them in memory. Nothing is stored, no signup.
How it works — honestly
We fetch your page plus robots.txt, llms.txt and sitemap.xml, then run deterministic checks on what came back — no AI judging another AI, no crawling the rest of your site. The score is the plain share of checks passed, so it is a to-do list, not a grade. It measures whether machines CAN read you, which is a precondition for being recommended, not a promise of it.
Want the red items fixed for you?
On WordPress, our free plugin does the boring half: llms.txt, structured data, crawler control and instant indexing. Everywhere else, Laspi writes the articles that give assistants something worth quoting.

Questions
Does a high score mean ChatGPT will recommend me?
No, and anyone promising that is selling something. The score measures whether assistants can read and understand your site at all. That is a precondition: fail it and you are invisible no matter how good the business is. Pass it and you are in the running, which is where the content work starts.
What exactly do you request from my site?
Your page, /robots.txt, /llms.txt and /sitemap.xml — four public GET requests, the same ones any crawler makes. We identify ourselves honestly in the user agent and store nothing.
Is llms.txt a real standard?
It is a young convention, not a ratified standard, and we say so. It costs nothing to publish and some assistants already read it, which is why it is a warning here rather than a failure.
Can I see how the checks work?
Yes. The audit runs on citeready, our own open-source Python package. Every rule and threshold is readable, and you can run the same audit yourself from the command line.
My site is behind Cloudflare or a login. Will it work?
If a page needs a login, a crawler can't read it either — that is the finding. Aggressive bot protection can also block us; if the check fails but the page opens fine in your browser, that gap is worth knowing about, because assistants hit the same wall.
