# Markdown is the native language of AI

When I ask in a workshop who has ever dragged a PDF into an AI chat, almost all hands go up. When I ask who knows what Markdown is, only a few remain. Yet that second one is probably the most underestimated piece of knowledge in working with AI.

## What Markdown is

Markdown is plain text with a few simple characters for structure. A hash for a title. Two asterisks around a word for bold. A hyphen for a list. That is all it is. You can read it in any text editor, and it still looks logical even without formatting.

Language models are trained on enormous amounts of text from the internet, and a large part of that is written in Markdown. It is the format in which they recognise structure best. A title is a title, a list is a list. Nothing needs to be deciphered.
