AI Crawler Accessibility Checker: Can AI Bots Reach Your Content?
AI crawlers like OAI-SearchBot, Claude-SearchBot and PerplexityBot need access to your content to include it in AI answers, and a firewall rule can refuse them without anyone noticing. Enter a domain below and Glippy asks that site for its home page as each of these crawler identities in turn, then reports only what the responses prove. Google-Extended and other robots.txt-only tokens have no User-Agent to send, so this check cannot speak to them.
The free check on this page runs from Glippy's edge network, which is a datacenter address that some firewalls refuse on sight. When that happens the honest answer is "we cannot tell from here", and the Glippy Chrome extension runs the same check from your own network instead.
Run the live AI crawler accessibility check
Glippy asks the domain for its home page as twelve different identities, from one address in one session. A plain Chrome browser, an unknown bot, a spoofed Googlebot, Chrome again at the end, and each of the eight AI crawler identities: three that index pages for AI answers, three that fetch a page live when somebody asks, and two that collect content for model training. Only the User-Agent changes between them, so a difference between them is evidence about the site's rules rather than about our IP address. Where the evidence is missing, the result says so rather than guessing.
What Are AI Crawlers?
AI crawlers are bots operated by AI companies to fetch web content for their language models and search systems. The major AI crawlers include GPTBot (OpenAI), ClaudeBot (Anthropic), and Google-Extended (Google), along with PerplexityBot, Bytespider, and others.
Common access issues, beyond what this check measures
The live check above measures only what the server returns to each crawler identity. Robots.txt rules, meta tags and client-side rendering are checked by the Glippy extension and desktop app, not here.
- robots.txt blocking - Many sites inadvertently block AI crawlers via robots.txt
- Robots meta tags -
noaiornoimageaidirectives that prevent AI indexing - JavaScript-only content - SPAs without server-side rendering that AI crawlers cannot parse
- Rate limiting - Aggressive bot protection that blocks legitimate AI crawlers
- Rendering issues - Content that requires client-side JavaScript to display
