Free llms.txt Generator
We'll generate a comprehensive llms.txt file tailored to your site so AI agents can read it at the root of your domain
What Is an llms.txt File?
An llms.txt file is a plain-text Markdown file placed at the root of your domain — at yourdomain.com/llms.txt — that gives large language models a concise, structured summary of your website. Where robots.txt tells crawlers what they may access and sitemap.xml lists your URLs, llms.txt explains what your site is about: who you are, what you offer, and which pages matter most.
The web is shifting from being browsed by people to being browsed by AI. ChatGPT, Claude, Perplexity, and emerging agentic browsers visit sites on behalf of users — reading content, comparing options, and taking actions. llms.txt gives those AI agents a fast, reliable entry point to your site, and it's one of the core discoverability signals checked in Lighthouse's agentic browsing audits.

Why Your Website Needs an llms.txt File
AI assistants are becoming a primary discovery surface, sitting between users and the open web. When someone asks ChatGPT to compare tools, Claude to research a vendor, or Perplexity to find a service, those models decide which sites to read, cite, and recommend. An llms.txt file gives them a structured summary they can parse instantly — no DOM crawling or rendering required — so your business is described accurately instead of being left to inference.
This makes llms.txt one of the simplest, highest-leverage steps in Generative Engine Optimization (GEO): traditional SEO optimizes for human searchers on Google, while GEO optimizes for AI models and agents that answer questions and act on behalf of users. llms.txt pairs naturally with semantic HTML, strong accessibility, and emerging standards like WebMCP.
Who Should Create an llms.txt File?
- SaaS companies — make sure AI assistants describe your features and pricing accurately when users ask them to compare tools
- E-commerce businesses — help AI shopping agents surface your catalog when users delegate buying decisions
- Service providers — tell AI agents where you operate, what you offer, and how to start a conversation
- Content creators and documentation sites — point AI models directly at your canonical sources so citations stay accurate

An llms.txt file is a plain-text Markdown file placed at the root of your domain (yourdomain.com/llms.txt) that gives AI models and agents a structured summary of your website — what your business does, who it serves, and which pages matter most. It helps ChatGPT, Claude, Perplexity, and agentic browsers understand your site without crawling every page.
Upload the file to the root of your domain so it's accessible at yourdomain.com/llms.txt — the same location pattern as robots.txt and sitemap.xml. AI agents and audits like Lighthouse look for it at exactly that path.
No. robots.txt controls which crawlers can access your site, while llms.txt provides context about your business for AI models to read. They complement each other: robots.txt is about access, llms.txt is about understanding. For the best AI visibility, publish both.
llms.txt is a Generative Engine Optimization (GEO) signal rather than a traditional Google ranking factor. It helps AI assistants and agents describe, cite, and recommend your site more accurately, and Lighthouse checks for it in its agentic browsing audits as a discoverability signal.
llms.txt uses plain Markdown: an H1 with your site name, a short blockquote summary, and H2 sections containing lists of important links with one-line descriptions. This generator produces that structure for you automatically.
Yes. Enter your website URL and the tool crawls your key pages and generates a complete llms.txt file you can copy or download — free, with no credit card required.
