llms.txt Generator

Build a spec-correct llms.txt file for your site — H1 name, blockquote summary and sectioned Markdown link lists that guide AI assistants to your best pages.

Sections

Upload the file to your site root as /llms.txt. If you also publish full page contents for LLMs, the convention is a separate /llms-full.txt containing the concatenated Markdown of every linked page.

About the llms.txt Generator

The llms.txt Generator builds the emerging /llms.txt file — a Markdown file at your site root that tells AI assistants what your site is and which pages matter. Fill in your site name, a short summary and sections of links, and a spec-correct file is assembled live.

The format follows the llmstxt.org proposal exactly: an H1 with the site name (the only required element), a blockquote summary, optional context paragraphs, then H2 sections of Markdown link lists with optional notes. A section named Optional has special meaning — agents may skip it when context is tight.

Everything is generated 100% locally in your browser and nothing is uploaded. As answer engines and AI crawlers become real traffic sources, llms.txt is a cheap, low-risk way to point them at your canonical documentation instead of letting them guess.

Frequently asked questions

What is llms.txt?

llms.txt is a proposed standard file at your site root — like robots.txt, but for AI assistants. It is plain Markdown: an H1 site name, a blockquote summary and sections of curated links, giving language models a concise, reliable map of your most useful content.

Where do I put the llms.txt file?

At the root of your domain, so it is reachable at https://yourdomain.com/llms.txt. Serve it as plain text or Markdown. Subdomains are treated as separate sites, so each can have its own file.

What is llms-full.txt?

A companion convention: while llms.txt is the curated index, llms-full.txt contains the full concatenated Markdown content of the linked pages, for tools that prefer everything in one request. It is optional — start with llms.txt and add the full version if your docs tooling can generate it.

Does llms.txt help SEO?

It does not affect Google's classic rankings today. Its value is with AI assistants and answer engines: it increases the chance they describe your site accurately and cite the pages you actually want cited, which is the emerging discipline people call GEO or AEO.

What does the Optional section mean?

In the llms.txt spec, a section titled Optional marks links that can be skipped when an AI has limited context space. Put must-read documentation in normal sections and background material under Optional.
