What is llms.txt?

llms.txt is a proposed standard for websites to communicate structured information about themselves to large language models (LLMs) and AI crawlers. Similar to how robots.txt guides web crawlers and sitemap.xml helps search engines, llms.txt gives AI systems a concise, machine-readable overview of a project — its purpose, key documentation links, and important context — without requiring the AI to infer everything from raw HTML.

The format uses Markdown and follows a loose convention: a short description at the top, optional sections with relevant links, and any context the AI should know before working with or referencing the project. The goal is to make it easier for LLMs to understand what a website is about and where to find authoritative information.

Tool description

This tool uses AI to generate a ready-to-use llms.txt file for your project. Provide your project name, a brief description of what it does, and optionally your website URL — the AI will produce a well-structured file you can place at the root of your domain.

Examples

Input:

  • Project name: Rapid Tool Set
  • Description: A collection of 100+ free online developer tools including converters, generators, calculators, and formatters.
  • Website URL: https://rapidtoolset.com

Output (excerpt):

Features

  • AI-generated content: Produces contextually appropriate, well-structured llms.txt output based on your inputs
  • Minimal input required: Only project name and description are required; the website URL is optional
  • Markdown format: Output follows Markdown conventions compatible with the llms.txt standard
  • Instant copy: Copy the generated file content with one click for immediate use
  • Customizable starting point: Use the output as-is or as a base to expand with your own links and sections

How it works

The tool sends your project name, description, and optional URL to an AI model, which crafts a llms.txt file that follows the emerging convention. The AI ensures the output includes a concise summary block and any relevant sections that help language models understand the project at a glance.

Tips

  • The more specific your description, the more useful the generated file will be for AI systems.
  • After generating, add links to your actual documentation pages, API references, and changelogs to maximize usefulness.
  • Place the final file at https://yourdomain.com/llms.txt so AI tools and crawlers can discover it automatically.
