Free AI Crawler Access Checker - No Account Required
Are AI Crawlers Blocked from Your Website?
Free AI crawler access checker - test accessibility for GPTBot, ClaudeBot, PerplexityBot and 7 more AI crawlers in seconds.
What you get
Instant robots.txt analysis for all 10 major AI crawlers
Most sites block AI crawlers accidentally - through wildcard Disallow rules, CDN bot-protection configs, or outdated robots.txt files written before AI engines existed. This inspector finds the problem in seconds.
Once your crawlers are unblocked, generate a free llms.txt file → so AI engines understand your brand context, not just access your pages.
Why it matters
Crawl = Indexing
If GPTBot can't read your site, ChatGPT can't recommend your brand - regardless of your content quality or domain authority.
Silent failures
Most sites inadvertently block AI crawlers through overly restrictive robots.txt files or CDN bot-protection rules.
Quick wins
Fixing crawler access is often the highest-ROI AEO action. A single robots.txt change can unlock AI visibility within days.
