CrawlCheck
Audit robots.txt for 60+ AI crawlers. Free, instant.
CrawlCheck is a free client-side auditor that shows exactly which AI crawlers — GPTBot, ClaudeBot, PerplexityBot, Bytespider and 60+ more — your robots.txt allows or blocks. Paste your robots.txt and get an instant verdict per bot, plus a ready-to-use policy generator that blocks or allows AI training and search crawlers with one click. It also checks broken links, audits meta tags and generates JSON-LD structured data. Everything runs 100% in your browser — no signup, no server upload, no data leaves your machine.

CrawlCheck started as an internal tool: we kept getting asked "can ChatGPT see my site?" and the honest answer required manually tracing 60+ crawler user-agents through robots.txt. So we built the auditor we wanted — paste your robots.txt, get a per-bot verdict instantly, and generate a clean policy with one click. Everything runs client-side, so nothing leaves your browser. We would love feedback on the policy generator: which AI crawlers do you block today, and did the tool miss any?
