AI assistants are becoming the new front door to the web. Find out whether ChatGPT, Claude, Perplexity and Google AI can access your site in seconds.
How it works
Paste your website address. No account or credit card required. The check starts immediately.
We read robots.txt and llms.txt for declared rules, then send live requests using each crawler's real user-agent string. An agent only counts as allowed if both signals agree, so a site can't claim access on paper while quietly blocking it in practice.
Get a 0-100 score, an agent-by-agent access map, a score for every page we analyzed and a list of fixes ranked by impact.
A site can declare access in robots.txt and still block it in practice. We check both, so "allowed" always means both signals agree.
We read robots.txt and llms.txt, the same files search engines already use.
We also send real requests using each crawler's actual user-agent string to see what happens in practice, not just what's declared.
A representative example. This is exactly what you receive the moment your check completes.
AI Visibility Score
Limited visibility. Most AI platforms cannot see your content.
Visibility Signals

Not scored. Blocking model-training crawlers is a licensing choice, so some training crawlers are allowed, others are turned away.
Agent-by-Agent Access · robots.txt + live probe
Robots.txt means the file disallows this crawler. Server means the live request itself failed. Training crawlers show as opted out rather than blocked, and cost no points either way.
How the Score Is Calculated
Based on robots.txt rules, a live homepage request with each crawler's user agent, and 5 analyzed pages. Cached for 60 minutes.
Performance Matrix · 5 pages
Across 2 hosts. Technical Infrastructure is a property of the host, so pages on the same host share it. AI Visibility varies per page because robots.txt rules are path-scoped.

Why it matters
Classic SEO gets your site ranked. AI SEO, also called generative engine optimization (GEO), decides whether AI crawlers can read your site well enough to recommend it at all.
OpenAI's weekly active users more than doubled in the past year. Every one of them could be shown a competitor's site instead of yours.

FAQ
It shows how easily AI platforms can find, read and quote your site right now, out of 100 points. Three things drive it: whether search and answer engines are allowed to reach your pages, whether your content is structured so an AI can extract it, and whether the technical basics are in place, including robots.txt, sitemap.xml, llms.txt, HTTPS and a fast response.
robots.txt is a text file at the root of your domain that tells crawlers, including search engines and AI bots, which parts of your site they can access. It's the same file that already controls how Google indexes your pages.
llms.txt is a newer file, published at yourdomain.com/llms.txt, that gives AI systems a clean, direct summary of your site's content. It isn't required yet, but publishing one is an easy way to tell AI answer engines what your site is about.
13 crawlers across three categories: search engines like Googlebot and Bingbot, AI training crawlers like GPTBot, ClaudeBot and Common Crawl, and AI answer engines like ChatGPT's live browsing, Perplexity and OpenAI's search crawler.
Yes. isvisible.ai has a public API, and the exact request format is published at isvisible.ai/llms.txt specifically so AI assistants can read it. Ask ChatGPT, Claude or any AI assistant with web access to check a domain using the isvisible.ai API, and it can send the request and read the score back to you.
ChatGPT, Claude, Perplexity and Google AI Overviews are becoming a new way people find and evaluate businesses. If your site blocks these crawlers, your content can't be cited or recommended in AI answers, even if it ranks well in traditional search.
Yes. Enter your URL and get a full report in seconds, no account or credit card required.
AI Visibility is half the score, Content Structure is a quarter, and Technical Infrastructure is the last quarter. Valid schema markup, quotable schema types and freshness dates add up to 10 bonus points on top. If a site has no robots.txt and the live probe can't run either, access can't be confirmed, so those points count at half weight until one of the signals is available.
Yes. We read your sitemap.xml, spread the selection across different sections of the site rather than ten sibling doc pages, and follow the subdomains your homepage links to. Every page gets its own score, so you can see that your homepage is fine while your docs are unreadable. The headline score still describes the domain you entered.
No. Training crawlers like GPTBot, ClaudeBot and Common Crawl are reported as a consent posture, not scored. Blocking them is a licensing decision and it costs you nothing here. Only search and answer engines count toward your score, because those are what decide whether your site can be found and cited today.
