The record.

6.87% of 299,427 ranked domains publish an llms.txt.

Every audited domain joins the llms.txt Registry, so the audit is comparative: your site against what the web actually does, not against a checklist alone. Nobody can backfill that record later.

  1. See your verdict Type your domain into the question above. The score, the five category readings and every finding are free. No account. Free
  2. Get the fixes Each finding names the fix and where to apply it, and re-checks it the moment you have shipped. That comes with a free account. When the fix is an llms.txt, we write it from your sitemap. Free account
  3. Keep it that way We re-run the audit on a schedule and email only when something changes. Deep Site Crawl reads every page, not just the front door. Pro

Questions

Is the AI Readiness Audit free?

Yes. The score and all 41 findings are free and need no account. The fix for each finding, a re-check once you have shipped it, and monitoring come with a free account. Paid plans add deep page-level crawls and scheduled re-audits.

Does this help me rank on Google?

No, and we will not tell you it does. Google Search does not read llms.txt. The audit measures how ready your site is for AI systems and agents: whether they can reach it, find what matters, understand it, and quote it safely.

What is llms.txt and why do I need it?

llms.txt is a markdown file that gives AI systems a structured summary of your website -- your key pages, topics, and how you'd like to be referenced. Think of it as a robots.txt, but for AI assistants like ChatGPT, Claude, and Gemini. It is based on an open specification and takes a few minutes to set up.

Is llms.txt the same as robots.txt?

No, they serve different purposes. robots.txt tells search engine crawlers which pages to index or avoid. llms.txt tells AI models how to understand and reference your content when generating responses. Both are important for modern web management.

Which AI models support llms.txt?

Any tool can choose to read it, and documentation platforms and coding agents do. No major AI provider has confirmed that its search product reads llms.txt, and independent crawler logs show AI bots fetch it rarely. Anthropic publishes one on its documentation site, and our examples directory catalogues 840+ websites that have adopted the format. Treat it as a low-effort, forward-looking step, not a visibility lever.

How do I install the file on my website?

Upload the generated llms.txt file to your website's root directory (same level as your homepage). For example: yoursite.com/llms.txt. We provide detailed deployment instructions for popular platforms including Shopify, WordPress, GitHub Pages, and more.
