Enter any domain and live-fetch their actual llms.txt. Validates format, checks every major AI bot declaration, and flags conflicts with robots.txt — for your own site or any competitor.
llms.txt is an emerging specification, analogous to robots.txt, that gives website owners a structured way to declare their content's availability for AI training, retrieval, and citation. Where robots.txt controls crawl access at the page level, llms.txt operates at the intent level — telling AI systems what the site is, what it covers, and how its content should be used.
The file lives at the root of your domain, is plain text, and follows a simple key-value format. A well-formed llms.txt includes the site name, a description of what the site covers, contact information, and per-bot Allow or Disallow declarations. Engines that support llms.txt — including GPTBot and PerplexityBot — check for the file before indexing content.
The specification is still maturing. Different AI engines read it with different levels of strictness, and not all treat it as binding the way browsers treat robots.txt. But sites with a correctly formatted llms.txt consistently show higher citation rates than comparable sites without one — the signal it sends about technical AEO maturity compounds over time.
This tool is for anyone who needs to verify AI bot configuration rather than assume it's correct. The most common users are technical SEOs auditing a client site, content strategists who want to know why their content isn't being cited despite good AEO scores, and competitive intelligence practitioners monitoring how rivals configure their AI access settings.
