Free checks of how AI assistants and search crawlers see your site. No sign-up needed.
An AI assistant can only recommend a site its crawlers may read. The AI crawler checker reads your robots.txt, llms.txt and home page the way GPTBot, ClaudeBot, PerplexityBot, Googlebot and ten other crawlers would, and says for each one whether it may read your site and how to fix it if not. Being readable is the first step; what assistants then say about you is what Vouch measures, as the methodology explains.
