Markdown vs HTML for AI workflows

Both formats can carry structure. The better choice depends on whether compact readability or rich presentation semantics are more important.

bottom line

Which should you choose?

Choose Markdown for compact, editable, text-first AI context. Choose HTML when rich semantics, attributes, styling, or direct browser rendering are central.
