llms.txt Generator Tool
Build AI-friendly markdown documentation for ChatGPT, Gemini, Claude & RAG search models.
What is an llms.txt File? (AI Web Scraping Rules File)
An llms.txt file is a standardized Markdown document placed at the root directory of a website (e.g., example.com/llms.txt). It serves as an AI web scraping rules file that helps Large Language Models (LLMs), ChatGPT, Claude, and Gemini understand your website structure, prioritize important pages, and cite your content accurately in generative AI search results.
