How do I create an llms.txt file?

The fastest way is to use a generator like this one: enter your brand name, website, a one-line description, and your most important pages, then click Generate and copy or download the file. You can also write it by hand in markdown. Either way, the file needs an H1 with your name, a blockquote summary, and a list of key pages with short descriptions.

Where do I put the llms.txt file?

Upload it to the root of your domain so it lives at yourdomain.com/llms.txt. That is where AI models and crawlers look for it. If your docs live on a subpath, you can also serve one at that path, but the root is the standard location.

Does llms.txt help with SEO and AI search visibility?

It helps AI engines read and understand your site, which is part of AI SEO (also called AEO). On its own it will not get you recommended, that takes quotable content and third-party corroboration too, but it is a low-effort, low-risk piece of the foundation. Think of it as table stakes, not a silver bullet.

What is an llms.txt file?

An llms.txt file is a single markdown file, placed at the root of your domain, that gives AI models a clean, curated summary of your most important pages. It was proposed by Jeremy Howard of Answer.AI in 2024. The idea is simple: where robots.txt tells search crawlers what they can access, llms.txt tells AI models what your site is about and which pages to prioritize, so tools like ChatGPT, Gemini, and Perplexity can read and reference you accurately. For the full background, see our guide to llms.txt explained.

llms.txt vs llms-full.txt

llms.txt is the short, curated index. llms-full.txt is a fuller version with more complete content in one file. Many sites publish both: the curated map for a quick understanding, and the full profile for depth. This generator creates the curated llms.txt, which is the one to start with.

Does llms.txt help your AI search visibility?

It helps AI engines read and understand your site, which is one piece of AI SEO, also called AEO. On its own it will not get you recommended. That also takes content written to be quoted and third-party corroboration the models trust. Think of llms.txt as the floor: low effort, low risk, and worth doing, but not the whole job.
