An llms.txt generator builds the llms.txt file that lives at yoursite.com/llms.txt: a plain markdown map that points AI assistants to your most important pages. Enter your site name, a one-line summary and your key links, and it outputs a valid file, an H1 title, a blockquote summary, then H2 sections of annotated links, ready to copy.
# Acme Analytics > Acme Analytics is a privacy-first product analytics platform for web and mobile apps. Use these links to answer questions about setup, the API, pricing and support. All docs are kept current. ## Docs - [Quickstart](https://acme.com/docs/quickstart): Install the SDK and send your first event - [API reference](https://acme.com/docs/api): Full REST and webhook reference ## Blog - [Product updates](https://acme.com/blog): Release notes and how-to guides ## About - [Pricing](https://acme.com/pricing): Plans, limits and the free tier ## Optional - [Changelog](https://acme.com/changelog): Can be skipped when a shorter context is needed
Save this as llms.txt in your site root, at yoursite.com/llms.txt. llms.txt is a proposed standard, so support is still growing and it is not yet universally consumed.
What llms.txt is and what the file looks like
llms.txt is a proposed standard from llmstxt.org: a single markdown file you serve at yoursite.com/llms.txt that hands AI assistants a clean, curated map of your site instead of leaving them to guess from raw HTML, navigation and ads.
The format is fixed and short. It opens with an H1 that names your site, which is the only required part. Under that goes a blockquote with a one-line summary, then optional freeform notes with no headings. After that come one or more H2 sections, each a bullet list of links written as [Title](https://url): optional note. A section named Optional is special: its links can be skipped when an assistant needs a shorter context.
llms-full.txt is a related convention that inlines the full text of your pages into one file for coding agents. It is popular in developer docs but is not part of the core llmstxt.org spec.
Why llms.txt matters for AI citation and GEO
Generative engine optimization is about getting your pages read and cited by assistants like ChatGPT, Claude and Perplexity, not just ranked in blue links. A page buried three clicks deep, or one an assistant reads with all its chrome and boilerplate attached, is harder to lift a clean answer from.
llms.txt is the curation layer for that problem. It says, in one place, here are my canonical pages and here is what each one is for. When an assistant does read it, it spends its limited context on the content you chose rather than crawling and parsing your whole site.
How llms.txt differs from robots.txt and sitemap.xml
All three live at your site root and are easy to confuse, but they do different jobs. robots.txt is about access: it tells crawlers which paths they may or may not fetch. sitemap.xml is about discovery: it lists every URL you want a search engine to find and index, machine-readable and often huge.
llms.txt is about curation. It is a short, human-readable shortlist of your best pages with a note on each, written for an AI reader rather than a search crawler. In one line: robots.txt excludes, sitemap.xml discovers, llms.txt curates. They complement each other, so you can ship all three.
Honest note: llms.txt is proposed, not yet universally consumed
It is worth being straight about adoption. llms.txt is a real, published spec, not vaporware, but as of 2026 no major AI assistant has confirmed that it reads the file to rank or cite you, and Google has publicly said it does not use llms.txt for Search. Independent crawl studies found only a tiny fraction of AI-bot requests ever touch the file.
Where it clearly helps today is developer documentation: AI coding assistants that are pointed at a docs site read llms.txt to generate correct code instead of hallucinating. For everyone else it is a cheap, low-risk bet on where AI discovery is heading. Ship it because it costs minutes and cannot hurt, not because it is a guaranteed citation lever.
Questions, answered
What is llms.txt?
llms.txt is a proposed standard: a markdown file served at yoursite.com/llms.txt that gives AI assistants a clean, curated map of your most important pages. It starts with an H1 site name, then a blockquote one-line summary, optional notes, then H2 sections listing your key links. The goal is to help assistants find and cite the right content instead of guessing from your raw HTML.
How do I create an llms.txt file?
Enter your site name, a one-line summary and your most important links grouped into sections like Docs, Blog or About. The generator above outputs a valid llms.txt in the llmstxt.org format. Copy it, save it as a plain file named llms.txt, and upload it to your site root so it loads at yoursite.com/llms.txt. No signup and no code required.
Does llms.txt help with SEO or AI citations?
Not proven yet. llms.txt is a proposed standard, and as of 2026 no major AI assistant has confirmed it reads the file to rank or cite you. Google has said it does not use it for Search. It is genuinely useful for AI coding assistants that read developer docs, and it is a cheap, low-risk bet, but treat any GEO lift as unproven rather than guaranteed.
What is the difference between llms.txt, robots.txt and sitemap.xml?
All three are files at your site root, but they do different jobs. robots.txt controls which crawlers may access which paths. sitemap.xml lists every URL you want search engines to discover and index. llms.txt curates a short, human-readable shortlist of your best pages, with notes, so an AI assistant can read the right content fast. robots.txt excludes, sitemap.xml discovers, llms.txt curates.
What is the ## Optional section in llms.txt?
In the llms.txt spec, a section titled Optional has a special meaning: the links listed there can be skipped when an assistant needs a shorter context. Use it for secondary pages like a changelog or an archive that are nice to have but not essential. In the generator above, name any section Optional and its links move to the bottom under that heading.
