Beyond the README: The Evolution of Markdown in the Age of Generative AI

Markdown is moving from a human-readable writing format to a low-cost interface for LLM output and structured content.

Built on CommonMark and GitHub Flavored Markdown, tools like ChatGPT, Claude, and Gemini are using it more deeply in docs and workflows.

Extensions such as MDX, content collections, and YAML frontmatter are turning Markdown into a core layer for dynamic docs and developer tooling.

In practice, Markdown is evolving into a shared interface for humans and AI across documentation, content, and software workflows.
