llms.txt Generator

llms.txt is a markdown file at the root of your domain that gives large language models a curated, structured map of your site. It tells AI assistants like ChatGPT, Claude, and Perplexity which pages matter, what each one is about, and where to look first. Think robots.txt, but for AI retrieval instead of crawler permissions.

At the root of your domain — yoursite.com/llms.txt. It must be served as plain text. Some teams also publish llms-full.txt with longer-form excerpts of their key pages, which AI assistants can ingest more directly than HTML.

Indirectly — it doesn't influence Google rankings. But it does help AI search visibility: assistants that ground in real-time content (Perplexity, Google Gemini search, ChatGPT browse) increasingly check structured signals like llms.txt to choose which pages to cite. Adoption is still early; getting one in place is a small, cheap edge.

llms.txt is a short index — page titles, links, one-sentence descriptions, organized by section. llms-full.txt is the long-form version with the actual page content embedded inline, optimized for AI consumption (no nav chrome, no marketing copy). Most sites start with just llms.txt.

Yes. They serve different purposes. robots.txt tells crawlers (Googlebot, Bingbot) which paths they're allowed to fetch. llms.txt tells AI assistants which pages are worth reading and how the site is organized. Neither replaces the other.
