llms.txt is the brand card AI assistants read first — a plain-markdown file at your root that says who you are and where your important pages live. Enter your domain: we read your live homepage and assemble the file from your real title, description and links.
A file in the llmstxt.org shape: an H1 with your site name, a blockquote summary, and link sections built ONLY from pages found on your homepage — the generator cannot invent URLs. Review the output, adjust wording if you like, and serve it at /llms.txt as plain text.
Honestly: adoption by AI vendors is still uneven, and no engine guarantees reading it. It costs one static file, several crawlers already fetch it, and it is the cheapest way to control the first description of your brand an AI sees — a good bet, not a magic switch.
The full SeoVision audit checks your whole AI surface — crawler access, structured data, citability — and measures what assistants actually say about you.
