Is my llms.txt valid?

How do I create an llms.txt?

Which AI bots can crawl my site?
AI crawler access checker
Paste any URL — see which AI bots (GPTBot, ClaudeBot, PerplexityBot, OAI-SearchBot, Google-Extended, Applebot-Extended, CCBot, …) your robots.txt allows or blocks. Detects explicit rules + implicit fall-through to default.

Want the full picture?
These free tools each check one thing. A Crawlmind audit checks 70+ rules across every page (including real Core Web Vitals on rendered crawls) and ranks the fixes by impact.
