llms.txt
A proposed convention: a single Markdown file published at yourdomain.com/llms.txt that hands an AI system a clean, curated summary of who you are and links to your most important pages. Proposed by Jeremy Howard in September 2024. As of 2026 it is unratified, and no major LLM provider has confirmed reading it — worth shipping because it’s cheap and harmless, but not something to rely on.
