Getting Started

Overview

llms-txt.io helps you create and maintain llms.txt and llms-full.txt files — the clean, structured docs that AI coding assistants and agents read.

There are three ways to use it:

  • The free web generator — paste a URL, get a file. No account needed. Great for a one-off.
  • The API — generate and validate files programmatically from CI, scripts, or your own product.
  • Managed sites — register a site once and we keep its llms.txt / llms-full.txt current automatically, served from a stable URL.

The web generator is free forever. The API and managed sites are paid features — see Pricing.

The two files

  • llms.txt — a concise, link-first index of your site: a one-line summary and curated links with descriptions. Small, cheap, and the table-stakes file.
  • llms-full.txt — the full cleaned, concatenated markdown of your key pages. Larger and more valuable: it's the actual content an agent can read end to end. Available on the Starter plan and up.
