llms.txt Generator: Create llms.txt & llms-full.txt Free

What the llms.txt generator does

This tool creates an llms.txt file for your website: a plain-text, Markdown-formatted map that tells AI models and agents what your site is about and which pages matter most. You enter your URL, Etoolio fetches your homepage and key internal pages, writes a short description for each, and hands you two ready-to-download files, llms.txt (a concise index) and llms-full.txt (the same index plus the readable content of each page).

Why llms.txt matters in the AI-search era

Search is shifting from ten blue links to AI answers. Tools like ChatGPT, Claude, Perplexity and Google's AI Overviews read the web to answer questions directly, and they need to understand your site quickly and correctly. An llms.txt file is the emerging convention for that, the large-language-model equivalent of robots.txt or a sitemap. It gives AI systems a clean, curated summary instead of forcing them to guess from cluttered HTML, which improves how accurately they describe and cite you.

How to use it

Enter your website URL (for example example.com) and press Generate.
Wait a few seconds while Etoolio crawls your homepage and key pages and summarises each one.
Review the two files. Switch between the llms.txt index and the fuller llms-full.txt export using the tabs.
Copy or download the file you want.
Upload it to your site's root so it is served at https://yourdomain.com/llms.txt.

llms.txt vs llms-full.txt

llms.txt is a short index: your site name, a one-line summary, and a bulleted list of key pages, each with a link and a brief description. Keep this lean, it is meant to be scannable.
llms-full.txt is a larger export that also embeds the readable text of each page, so an AI model can ingest your actual content in one file. Use it when you want models to have the substance, not just the map.

Best practices

Put your most important pages first, your homepage, core product or service pages, documentation and key guides.
Keep descriptions factual and concise. One clear sentence per page beats marketing fluff, AI models quote what is unambiguous.
Update it when your site changes, just as you would a sitemap, so the summary stays accurate.
Pair it with crawler access. An llms.txt only helps if AI crawlers are allowed to read your site, check your robots.txt with Etoolio's AI Crawler Access Checker.

Good to know

The file is generated from the public pages of the URL you enter, nothing is stored afterwards.
llms.txt is a convention, not a guarantee, not every AI system reads it yet, but adoption is growing quickly and the file does no harm to have.
This tool is free with no signup, and works for any public website, not just your own.

llms.txt Generator, frequently asked questions

What is an llms.txt file?

llms.txt is a plain-text Markdown file placed at the root of your website (at /llms.txt) that gives AI models and agents a curated map of your most important pages and what they contain. It helps tools like ChatGPT, Claude and Perplexity understand and cite your site accurately.

How do I create an llms.txt file?

Enter your website URL into Etoolio's llms.txt generator. It fetches your homepage and key internal pages, writes a concise description for each, and produces both an llms.txt index and a fuller llms-full.txt export. Download either file and upload it to your site's root folder.

What is the difference between llms.txt and llms-full.txt?

llms.txt is a short index: your site name, a summary, and a linked list of key pages with one-line descriptions. llms-full.txt is a larger export that also includes the readable text content of those pages, so an AI model can ingest the actual content, not just the links.

Where do I put the llms.txt file?

Upload it to the root of your domain so it is served at https://yourdomain.com/llms.txt. That is the conventional location AI tools look for, the same idea as robots.txt but written for large language models.

Does llms.txt help with GEO and AI search?

Yes. Generative Engine Optimization (GEO) is about being understood and cited by AI answer engines. A clean llms.txt gives those engines a clear, structured summary of what your site offers, which improves how accurately they represent and reference you.

Is the llms.txt generator free and private?

Yes, it is free with no signup. Etoolio only fetches the public pages of the URL you enter to build the file, and does not store your site's content afterwards.
