Can AI engines even reach your site?

Find out in seconds — before you spend a thing. Site Check reads your live robots.txt and llms.txt and tells you, crawler by crawler, whether AI answer engines can fetch your pages. If their crawlers are blocked, nothing you publish can be cited.

Where it fits

Site Check covers the very first Generative Engine Optimization gate — crawler access — at the whole-site level. It is the natural first step for every new domain, before spending credits on a page-level URL Audit.

FAQ

Questions, answered.

What is a free AI visibility checker?+

A free AI visibility checker shows, at no cost, whether AI answer engines can find and read your website. Sailiently's Site Check is one: paste your domain and it reports, crawler by crawler, whether ChatGPT, Claude, Perplexity, Google AI and others are allowed to reach your pages — the first layer of AI visibility. It is free, with no credit card.

What does Site Check actually check?+

It reads your live robots.txt and llms.txt and reports, for each major AI crawler, whether it is allowed or blocked, plus whether your sitemap and llms.txt are declared.

Is Site Check really free?+

Yes. Site Check is always free — no credits and no card required. You only spend credits on audits and rewrites that complete.

Does Site Check tell me whether AI engines are citing me?+

No — and no free checker can be sure without querying each engine. Site Check measures whether AI crawlers can reach and read your site, which is the prerequisite for being cited. Whether an engine then cites you also depends on your page content (scored by the URL Audit) and your off-page authority.

Which AI crawlers does it check?+

The crawlers behind ChatGPT, Claude, Perplexity, Gemini / Google AI, Common Crawl, Apple AI and ByteDance — twelve in total, each checked on its own.

My site shows as blocked — what now?+

Remove the Disallow rules in robots.txt for the crawlers you want reading you, then run a URL Audit on a key page to score how readable its content is.

Check your site in the next sixty seconds.

Always free, no card. If crawlers are blocked, you’ll want to know today.
