I'd like to add that Calibre (ebook-convert on the CLI) has a mode for outputting a .txt file with markdown formatting. It can take HTML as input.

I tried that on a HackerNews page and the content of the output file foo.md was in html.

Sorry, had only tested it on my own site, which worked as expected:

  curl --silent https://tinyapps.org/ | pandoc --from html --to markdown_strict -o index.md
