The llms.txt Standard: Complete Specification & AI Search Manifest Guide

How to generate, format, and host /llms.txt to guide LLMs directly to your highest-value technical content.

Definition & Purpose

The /llms.txt file is an emerging web standard that provides AI crawlers and language models with a structured, token-efficient markdown summary of a website's key capabilities, documentation endpoints, and authoritative resources.

1. Why AI Search Needs /llms.txt

HTML pages are filled with navigation menus, footer links, tracking scripts, and cookie banners. When an AI crawler or coding assistant (such as Cursor, Perplexity, or Claude) visits your site, stripping away DOM noise consumes unnecessary tokens and risks missing key documentation.

Hosting an /llms.txt file provides a direct, unencumbered markdown roadmap that tells AI models exactly what your product does, where the official docs live, and how to cite your tools.

2. Standard llms.txt Syntax Example

Below is a production-ready example of how an /llms.txt file should be structured:

# Your Brand Name
