Free llms.txt generator

llms.txt is a plain-text Markdown file at the root of a website that tells AI models what the site contains and which pages matter most. It was proposed by Jeremy Howard of Answer.AI in September 2024 as an AI-era counterpart to robots.txt — guidance for language models rather than crawler permissions.

There is no public confirmation that OpenAI, Anthropic, or Google read it, and Google’s John Mueller has said Google does not use it. We would rather tell you that than sell you a file. Publish it because it costs almost nothing and may matter later — not because it will fix your AI visibility this quarter.

At your domain root, so it resolves at https://yourdomain.com/llms.txt. It is a static text file: upload it the same way you would upload robots.txt. On most CMS platforms that means the public or static folder; on WordPress, the site root directory.

An H1 with your site or company name, a one-line summary in a blockquote, then Markdown sections listing the pages a model should read, each as a linked title. Keep it to pages that explain what you do and answer real questions. A list of every URL you have is less useful than a short curated one.

No. robots.txt controls access — which crawlers may fetch which paths — and every major crawler honours it. llms.txt is about comprehension: it points a model at the pages that best explain what you do. robots.txt genuinely matters today; llms.txt is optional and currently unenforced.

On its own, almost certainly not. What measurably moves AI citations is the content itself — Princeton’s KDD 2024 study found cited sources raised visibility 40%, statistics 37%, and expert quotations 30%, while keyword stuffing lowered it 10%. Publish llms.txt in ten minutes, then spend the real effort on being quotable.
