Is AI Search Blind to Your Website?
Find out in seconds whether ChatGPT, Perplexity, and other AI bots can actually access your site, or if something is quietly blocking them.
AI Bot tester
The Problem
Most sites investing in GEO and AEO share the same blind spot: they assume AI bots can crawl them. Often, they can’t.
Your robots.txt rules, your firewall, or your CDN configuration may be blocking the exact bots you need to reach. No error shows up in your analytics. Your site just doesn’t appear in AI-generated answers, and you’re left wondering why your content isn’t getting cited by ChatGPT or surfaced by Perplexity.
This tool checks both layers: your robots.txt directives and your server’s actual HTTP response to AI bot user agents, then tells you whether those bots can get through.
How the AI Bot Tester Works
Enter any URL. The tool sends simulated requests using known AI bot user agents, then checks two things: whether your robots.txt allows or disallows those bots, and whether your server actually responds to them or returns a block. You get a clear verdict: allowed, blocked, or potentially restricted.
One note worth reading: some firewalls are smart enough to detect spoofed user agents, which means you could see a “pass” here and still have bots blocked in practice. The results are a strong signal, not a guarantee. If something looks off, the next step is testing with real bot traffic or checking your WAF rules directly.

Blocked
Potentially Restricted
Why AI Bots Testing matters now
AI search works differently from Google. ChatGPT, Perplexity, Google’s AI Overviews, and similar platforms pull from sources their crawlers can access. If GPTBot or PerplexityBot hits a 403 on your domain, your content never makes it into their training or retrieval pipeline, and you get optimized out of answers before the conversation even starts.
Fixing a robots.txt rule takes five minutes. Knowing you need to fix it takes this tool.
What the tool checks
The tester evaluates two access points that AI bots encounter when they try to crawl your site. First, your robots.txt file: whether known AI bot user agents like GPTBot, ClaudeBot, PerplexityBot, and others are explicitly allowed, disallowed, or missing from your directives entirely. Second, your server’s live HTTP response: whether the actual request gets through or gets blocked at the firewall or CDN level, regardless of what your robots.txt says.
Those two checks together give you a complete picture of AI bot access on your domain.
Use This Before You Do Anything Else
Before you write a single piece of GEO-optimized content, before you restructure your FAQs for AI Overviews, before you spend another hour on appearing in AI answers, run this test. If bots can’t reach your site, none of that work will pay off.

The tool tests against major AI crawler user agents including GPTBot (OpenAI/ChatGPT), PerplexityBot, ClaudeBot (Anthropic), Google-Extended, and others commonly used by AI platforms to index and retrieve content.
Bot access is the prerequisite, not the guarantee. If your site is accessible, AI crawlers can index it. Whether your content gets cited depends on relevance, authority, and how well your content is structured for AI retrieval. Think of this test as clearing the first hurdle.
Start with your robots.txt file at yourdomain.com/robots.txt and check whether any AI bot user agents are explicitly disallowed. If the robots.txt looks clean but the tool still flags a block, check your WAF or CDN settings for rules that might be rate-limiting or rejecting unfamiliar user agents.
Yes, in one direction. Some enterprise firewalls detect that a user agent is being spoofed and serve a normal response to the test while still blocking real bots. If you suspect this is happening, validate against your server logs directly.
Yes, free to use with no strings attached.
AI bots either see your site or they don't.
You’ve spent time creating content worth finding. This tool tells you whether the bots powering AI search can actually find it. Run the test, and if something’s blocked, fix it before your next round of optimization.
