Can AI crawlers reach your site?
Enter a domain. This checker reads its robots.txt and tests it against each major AI crawler, then shows what is allowed, blocked, or limited.
Why crawler access comes first
If AI can't crawl you, it can't cite you
Every answer engine starts by fetching web pages. If your robots.txt disallows an AI crawler, that engine has no first-party access to your content — so it cannot describe, recommend, or cite your brand, no matter how good your pages are.
Blocking happens more often than teams expect: a robots.txt copied from a template, a security product, or a CDN toggle can quietly disallow GPTBot or PerplexityBot. This checker makes that visible in one step.
What blocking an AI crawler costs you
- ChatGPT can't retrieve your pages when users ask
- Perplexity can't cite you as a source
- Google's AI features skip your content for grounding
- Competitors that allow crawlers get the answer space
How the AI Bot Access Checker works
Enter your domain and the checker reads your live robots.txt, then evaluates it the way each AI crawler would.
Match every AI crawler
It applies the most specific matching rule for each bot, exactly like the crawler would, including the wildcard group.
See allowed vs blocked
Each engine is marked allowed, blocked, or partial, with the reason — so you know what to change.
The crawlers that matter

FAQs
Clear answers about AI mentions, AI citations, ChatGPT visibility, Perplexity citation readiness, and when a full audit is worth running.
What does the robots.txt AI bot checker do?
It reads your site's robots.txt and shows whether each major AI crawler — GPTBot, OAI-SearchBot, ClaudeBot, PerplexityBot, Google-Extended, and more — is allowed or blocked. If a crawler is blocked, that engine cannot read your pages to mention or cite you.
Why does AI crawler access matter for visibility?
Answer engines can only cite pages they are allowed to fetch. If GPTBot or PerplexityBot is disallowed in robots.txt, ChatGPT and Perplexity have no first-party access to your content, so you are far less likely to be named or cited in their answers.
Which AI crawlers does it check?
GPTBot and OAI-SearchBot (OpenAI / ChatGPT), ChatGPT-User, ClaudeBot (Anthropic), PerplexityBot, Google-Extended (Gemini and Google AI Overviews), Applebot-Extended, and CCBot (Common Crawl, which feeds many language models).
Does allowing AI crawlers guarantee I get cited?
No. Access is necessary but not sufficient. Being crawlable only means the engine can read you — whether it actually mentions and cites you depends on your content, entity clarity, and third-party evidence. That is what the full AEOMaster audit measures.
Is it bad to block AI crawlers?
It depends on your goal. Blocking can protect content from training, but it also removes you from AI answers that rely on live retrieval. If you want AI visibility, the retrieval-oriented crawlers such as OAI-SearchBot, PerplexityBot, and Google-Extended should usually be allowed.
How often should I check this?
Any time you change robots.txt, migrate your site, or add a CDN or security layer such as Cloudflare's AI bot blocking, re-check — those changes can silently block AI crawlers without you noticing.
Beyond this tool
This checker confirms AI crawlers can reach your site. AEOMaster turns that into a full one-time audit of whether AI answers actually mention and cite you — with prioritized fixes.
Prompt-level results across ChatGPT, Claude, Perplexity, Gemini, and Google AI — not just crawl access.
The sources AI answers cite, and the pages and citations you are missing.
Every finding ranked by expected impact and effort, so you know what to fix first.
Each issue comes with the why, the steps, and an example you can act on.
Re-run it after you ship fixes to confirm access and visibility improved.
From crawler access to AI citations
AEOMaster turns this access check into a one-time AI visibility report: prompt-level findings, citation gaps, competitor context, and prioritized fixes you can re-run after each change.
