Open pathAI visibility diagnostic
Enter a public page URL to check the robots.txt policy for major AI crawler tokens and run a live reachability diagnostic at the same time. The result keeps these signals separate: an allowed robots rule does not guarantee a CDN or WAF will let a crawler through, while a missing crawler-specific rule usually falls back to the wildcard policy.
Quick answer
The AI Crawler Access Checker reads the site's robots.txt rules for GPTBot, ChatGPT-User, ClaudeBot, Claude-SearchBot, PerplexityBot, and Google-Extended, then pairs them with a live anti-bot reachability test. It distinguishes publisher policy from technical blocking instead of treating robots.txt as proof of access.
Use this to separate explicit robots.txt rules for major AI crawlers from CDN, WAF, or anti-bot reachability problems.

Example output before you run the tool
| Crawler | robots.txt policy | Live reachability |
|---|---|---|
| OpenAI training | not specified | run to test |
| Google Gemini | not specified | run to test |
Use the URL whose path you want to evaluate, not only the homepage.
The tool checks crawler-specific groups first, then the wildcard group, using the longest matching path rule.
Crawlora runs its anti-bot diagnostic to identify whether the page is reachable from its test environment.
Review publisher policy and technical reachability independently before changing robots or CDN rules.
A crawlable example of the decision this tool helps you make; run your own URL for the current live result.
A crawler can be allowed by robots.txt while the live edge still blocks automated access. Read declared policy and live reachability as two independent signals.
Illustrative disagreement state. Run the exact production URL for a current verdict.
