AI agents and LLMs read llms.txt to understand your site before they recommend it, cite it, or buy from it. Only ~1 in 10 sites has one. Generate yours in 30 seconds below — or check whether any site already passes.
Enter a URL — we'll check its llms.txt plus the 7 other things an AI buying agent looks for.
Signed offer manifests, agent-services discovery, schema.org offers, agent-payable endpoints — the full stack that makes AI agents able to find, trust, and pay you. The Agent-Ready Kit has a drop-in template for every one. Instant download. Agents can even buy it for you over x402.
A plain-markdown file at yoursite.com/llms.txt that tells large language models and AI agents what your site is, what it offers, and which pages matter. Like robots.txt, but for AI comprehension instead of crawl permission. Anthropic, Stripe, Zapier, Cloudflare and Vercel all publish one.
What format does it use?Markdown: an H1 with your site name, a one-line blockquote summary, then H2 sections with bullet lists of [page title](url): description. Short beats long — it's a map for machines, not a brochure.
Where do I put it?The root of your domain, so it's reachable at https://yoursite.com/llms.txt. Static hosts: drop it in the public folder. WordPress: a plugin or your host's file manager.
Do AI agents actually read it?Adoption is early but real — about 10% of studied domains publish one, and AI research and shopping agents check it because it's the cheapest way to understand a site without crawling everything. It's one signal of several: structured data, agent manifests and payable endpoints complete the picture — that's what the full audit scores.
