The record

llms.txt

What is llms.txt?

The proposed standard for telling AI systems what a site offers. Google says its Search doesn't read it; adoption, tooling, and the other engines are the live questions.

Two items, and between them they close half of the open question. Ahrefs shipped a free llms.txt generator in late July 2026, built on its analysis of adoption across 137,000 domains — tooling that drops the cost of publishing the file to near zero. Then Google's AI-features documentation answered its own half plainly: you don't need to create machine readable files, AI text files, or markup to appear in those features. What the record does not contain is the other half: no statement from OpenAI, Anthropic, Perplexity or Microsoft about whether their systems read the file, and no measurement anywhere tying its publication to citations. Adjacent to it, the wire has Time serving agent-readable markdown pages and selling ads inside them.
