AI Crawler Access Checker
See whether ChatGPT, Claude, Perplexity, Gemini and other AI crawlers can actually reach your website. If AI platforms can't crawl you, they can't cite you.
Checks twelve AI crawlers against your robots.txt and runs live fetches to detect edge-level blocks. Takes up to 15 seconds.
Frequently Asked Questions
Why does AI crawler access matter?
ChatGPT, Claude, Perplexity and Gemini can only recommend websites they have been allowed to fetch. If your robots.txt or Cloudflare firewall blocks their crawlers, your firm cannot be cited in AI answers — no matter how strong your content is.
What is the difference between a robots.txt block and an edge block?
A robots.txt block is a polite instruction in the /robots.txt file asking crawlers not to visit. An edge block is enforced at the server or CDN layer (e.g. Cloudflare, WAF rules) and returns HTTP 401, 403 or 429 to the crawler. Both stop AI platforms from reading your site.
What is the difference between GPTBot, OAI-SearchBot and ChatGPT-User?
GPTBot crawls pages to train future OpenAI models. OAI-SearchBot indexes pages for ChatGPT Search results. ChatGPT-User is the agent that fetches a page live when a user or GPT clicks a link. You generally want all three allowed.
Should I allow Google-Extended?
If you want to appear in Gemini and Google AI Overviews, yes. Google-Extended is an opt-out control that only affects AI training and generative answers — it does not change your normal Google Search ranking.
What if my site has no robots.txt at all?
That is fine. In the absence of a robots.txt file, all crawlers are allowed by default. This tool will report each bot as allowed unless an edge-level block returns a 401, 403 or 429.
