llms.txt: The File Every Site Should Ship in 2026
llms.txt tells AI crawlers what your site is about. Here is what it does, why it matters, and how to generate one for your site automatically.
llms.txt is the new standard AI search engines use to understand your site. Like robots.txt for AI. ChatGPT, Perplexity, Claude, and emerging crawlers read it to learn your topics, key pages, and tone before they cite you. Most sites do not have one. Most sites that do, ship a stub. Both are losing AI citations every day.
Pinealizer audits whether you have llms.txt, whether the format is valid, whether the page index is current, and whether your content matches the topics declared. Then Pinealizer can generate a proper llms.txt + llms-full.txt from your existing pages - including a markdown index of your priority content for citation extraction. Free scan exposes the gap; the generator ships in your dashboard.
