# Crawl Readiness > Check whether AI crawlers can read a website, generate the files that fix what's blocked, and monitor whether AI assistants actually mention a brand. Crawl Readiness is an AI-SEO / GEO (generative engine optimization) toolkit. The free readiness check evaluates a site's robots.txt against 50+ AI crawler user-agents (ChatGPT, Claude, Perplexity, Google AI, Grok, Copilot, Meta AI, Apple Intelligence and more), looks for llms.txt, agents.json, JSON-LD structured data, meta and X-Robots-Tag directives, Open Graph tags and Content-Signal directives, then returns a 0-100 score with fixes ranked by impact. No signup is needed for the check. Operated by Tundrastone, an Ontario, Canada business. ## What it does - [AI readiness check](https://www.crawlreadiness.com/): free, no signup.
