Result preview
Run the check to replace this preview with diagnostics for your domain or URL.
A useful llms.txt has a clear H1, short summary, sections, and priority links.
The free preview shows the first line clearly and blurs the remaining structure so the full file can be unlocked.
Full copy, download, and saved history require registration; llms.txt is still a helpful convention, not a guaranteed ranking factor.

AI Crawler Checker
Check whether robots.txt is reachable, whether major AI/search crawlers are blocked, and where to unlock the full crawler-by-crawler report. This is an access check, not proof that AI engines will cite, rank, or recommend the site.
GEO Audit
Use the free GEO audit as a diagnosis hub for crawler access, page understanding, citation structure, AI Overview blockers, llms.txt needs, and the next action plan.
llms.txt Generator FAQ
Is llms.txt required by AI platforms?
No. It is an emerging convention. Treat it as a site guide you control, not as a guaranteed AI ranking factor.
How do I install my llms.txt file?
Unlock the full preview, review the links and descriptions, then publish the final file at the site root so it is available at /llms.txt.
What is visible in the free llms.txt preview?
The free preview shows the value explanation, first readable line, H2/link/paragraph structure, validation findings, and the unlock path for the complete file.
How is llms.txt different from robots.txt and sitemap.xml?
robots.txt gives crawler access rules, sitemap.xml lists discoverable URLs, and llms.txt gives AI systems a human-readable guide to priority pages and context.
Does llms.txt guarantee AI visibility?
No. llms.txt can make priority content easier to understand, but it does not guarantee ranking, AI citations, or answer inclusion.
Does this tool consume AI tokens?
No. The MVP validates and generates Markdown using deterministic rules.
