Why should I create an llms.txt file?

With the increasing use of AI search engines, having an llms.txt file helps AI crawlers understand your site structure, which pages are relevant and how to navigate them. This can improve your site's visibility in AI-generated responses, driving qualified traffic.

Where should I place the llms.txt file?

The llms.txt file should be placed in your domain root, just like robots.txt. For example: https://yoursite.com/llms.txt. This way AI crawlers can find it automatically when they visit your site.

What is the standard format for llms.txt?

The format is based on simplified Markdown. It starts with an H1 heading (# Site Name), followed by a description in blockquote (> description), and then H2 sections (## Section Name) with Markdown link lists: - [Label](URL). It's a format readable by both humans and machines.

What's the difference between llms.txt and robots.txt?

robots.txt tells traditional crawlers (Googlebot, Bingbot) which pages they can or cannot scan. llms.txt instead is a positive guide for AI models: it indicates which content is available and how it's organized, helping LLMs understand and navigate the site in a structured way.

Is this generator free?

Yes, Primo's llms.txt generator is completely free, requires no registration and works 100% client-side. Your data is never sent to any server: everything is processed directly in your browser.

What is the llms.txt file?

The llms.txt file is an emerging standard that allows websites to communicate to Large Language Models (LLMs) which content is available and how it is structured. Think of it as a robots.txt for AI engines: while robots.txt tells traditional crawlers what they can scan, llms.txt guides AI models in understanding and navigating your site.

With the rise of ChatGPT, Claude, Gemini and other AI assistants that answer user questions by citing web sources, having a well-structured llms.txt file helps these models find, understand and cite your content in their responses, driving qualified traffic to your site.

The format is based on simplified Markdown: an H1 heading with the site name, a description in blockquote, and H2 sections with link lists. It is readable by both humans and machines, and is placed in the domain root (e.g. yoursite.com/llms.txt).
