The AI Web is a structured, machine-readable publishing layer built on top of the human web. Where the human web is designed for browsers and human readers, the AI Web is designed to be understood by AI systems ... language models, AI agents, answer engines, and autonomous crawlers.

An AI-web-ready website implements standards like schema markup, llms.txt, AI sitemaps, and AI endpoints so that AI systems can determine what the site covers, who created it, why it is trustworthy, and how its content relates to other known entities.

The term gained traction as AI answer engines (ChatGPT, Perplexity, Gemini) began citing web sources directly ... making machine-readability a practical requirement for any website that wants to be discovered and recommended by AI systems.
