AI Crawler Access Checker

An AI crawler access checker reads a site's robots.txt and tests the homepage path against well-known search and AI crawlers. It tells you which bots are allowed, which are blocked and which rule decides.

This tool fetches the address you enter once, from our server, and reports what a crawler would receive. The URL is not stored; only a short-lived rate-limit counter is kept. Results show the page at the moment of the check and can differ from what a logged-in browser or a bot with different headers sees.

How to read the result and act on it

Read the table by bot, then by rule. For each crawler you see whether it is allowed or blocked for the homepage path and which robots.txt line decided it. Check the result against your intent: if you want to appear in AI search, the search-oriented bots should be allowed, while you may choose to block training-focused bots separately. If a bot is blocked unintentionally, look for a broad Disallow rule or a wildcard group that catches it, edit robots.txt, and re-run the check. Remember that this test covers one path. If you have rules for sections of the site, test those paths manually too.

Common mistakes to avoid

Do not take an allowed result as proof that a bot can reach your site. A firewall, CDN rule or security plugin can block a crawler even when robots.txt allows it, so check server logs too. Another mistake is blocking every AI-related bot by pasting a list copied from the internet without learning which is a training crawler and which powers search. Avoid assuming that robots.txt hides content; it is a request to crawlers, not access control. Be careful editing a live file, since a stray Disallow: / blocks the entire site. Finally, bot names and policies change, so review your robots.txt every few months.

Does blocking GPTBot remove me from ChatGPT search?

Not necessarily. Different bots serve different purposes, such as training or search, so read each vendor's documentation to see which user agent controls which product.

Does blocking Google-Extended remove me from Google Search?

No. Google-Extended controls use of content for certain AI products and does not affect Search ranking or inclusion.

Can a firewall block crawlers even if robots.txt allows them?

Yes. CDNs and security tools can block bots regardless of robots.txt, so test with server logs too.

How do I check if my robots.txt blocks AI bots?

Open yourdomain.com/robots.txt and look at the user-agent groups for the bots you care about, or paste your site into a checker. Confirm which group applies to each bot and whether Disallow rules match the paths you want crawled.

What is the difference between a training crawler and a search crawler?

Some bots collect content to train models, while others fetch pages to power search or answer a user's request. Companies publish separate user agents so you can treat them differently. Check each provider's documentation for current names and purposes.
