How it works
Step 1
We read what is already public
Your home page and your sitemap, exactly as a retrieval bot would — the served HTML, no login, nothing rendered.
Step 2
We check for an existing file
If you already publish an llms.txt we show it first, so you can see what changed rather than overwriting work.
Step 3
You publish it at /llms.txt
Copy it, commit it at the root of your domain, and it is live. No tag to add, no build step, nothing to verify.
Questions
- What is llms.txt?
- A markdown file at the root of a domain that tells an AI assistant what the site is and which pages answer which question. It is an index read on a small budget, the way robots.txt is a rule read on a small budget.
- Do assistants actually read it?
- Support is uneven and the convention is young. It costs one file to publish and it is the cheapest legible statement of what your site is for, which is why we publish one ourselves at /llms.txt.
- Will this see pages behind a login?
- No. It reads only what a crawler reads: public HTML over a plain GET, with no credentials and nothing executed.
