Placed at the root of your domain (yourdomain.com/llms.txt), this plain-text file tells AI agents who you are, what you offer, and which pages matter — without making them infer it from cluttered HTML. It is an emerging convention specifically aimed at large language models.
Think of it as a curated briefing for machines: a clear description of your business, key pages with short summaries, and any guidance on how your content may be used. It complements robots.txt, which controls access, by adding meaning.
An agent fetches agenticfindability.com/llms.txt and immediately reads a tidy summary of the service, the main pages, and the company behind it — instead of scraping six pages to piece it together.
Why this matters for AI findability
An llms.txt file removes ambiguity at the exact moment an agent is deciding whether it understands you. It is one of the most direct, low-effort signals you can add to improve agentic findability.
