AI Crawler Access Checker

    Evaluate your robots.txt policy for OpenAI, Anthropic, Google, and Microsoft crawlers. See whether each search, retrieval, or training bot is allowed, which rule matched, and the exact change needed when access is blocked.

    Only one public HTTP or HTTPS page is fetched. Private and local addresses are rejected.

    What this tool measures

    Published robots.txt policy, page-level robots directives, and live reachability from this checker.

    How to use it

    1. 1

      Provide the input

      Enter a domain or page URL.

    2. 2

      Configure the check

      Compare search/retrieval crawlers with training crawlers.

      Copy a remediation rule when your policy differs from your intent.

    Move from a one-time check to continuous AI visibility

    Monitor prompts, competitors, mentions, citations, and the pages AI systems use. Then turn the evidence into content and client-ready reporting.

    If you checked a URL, its domain is carried into project setup in this browser.

    Research and official sources

    Recommendations are tied to current provider documentation, standards, academic research, or clearly labeled vendor studies.

    official

    OAI-SearchBot and GPTBot have different purposes. ChatGPT referral URLs use utm_source=chatgpt.com. ARIA semantics help browser agents interpret controls.

    Limitation: OpenAI can change crawler and product behavior; verify quarterly.

    official

    ClaudeBot, Claude-User, and Claude-SearchBot have distinct purposes and honor robots.txt.

    Limitation: Anthropic-specific guidance; verify user-agent details quarterly.

    Frequently asked questions

    Does this guarantee visibility in AI answers?

    No. The tool measures observable signals or calculates from your inputs. Retrieval, mentions, citations, and rankings remain controlled by each provider.

    Are search and training crawlers the same?

    No. OpenAI and Anthropic document separate user agents for search or user-directed retrieval and model training.
