AI-readiness
llms.txt
A plain-text manifest at /llms.txt that tells AI agents what your site is and where the canonical content lives. Early but rapidly adopting.
What it is
A markdown file at the well-known path /llms.txt that describes the site for LLM consumers — purpose, key sections, links to LLM-optimized content. Proposed by Answer.AI in 2024.
Why it matters
ChatGPT, Claude, and Perplexity-class tools are starting to honour llms.txt as the AI-equivalent of robots.txt + sitemap. Sites that ship it get cleaner citations.
Who it applies to
Every site that wants to be cited well by AI assistants.
