Show HN: A free 16-point check for how AI assistants see your website

A free tool announced on Show HN runs 16 checks on a submitted homepage to determine whether ChatGPT, Perplexity and Google AI can read, trust and cite the site, and reports which checks fail. The tool requires no signup, email or installation and completes in a couple of seconds, fetching only four resources: the server-rendered homepage, /robots.txt, /sitemap.xml and /llms.txt. Its authors describe the output as an automated snapshot of the same signals their paid audit starts from, not a prediction of ranking or citation.

Paste your homepage address. We run 16 checks that decide whether ChatGPT, Perplexity and Google AI can read, trust and cite you — and show you which ones you fail.

No signup, no email, nothing to install. Takes a couple of seconds.

What this looks at: your homepage as a server-rendered document, plus /robots.txt, /sitemap.xml and /llms.txt — four requests, nothing else. It is an automated snapshot of the same signals our paid audit starts from, not a prediction of where you will rank or get cited.
