Built a Tiny Site That Formats Markdown for Substack

I prefer to write blog posts in markdown, especially if I'm on the go, and historically I've manually reformatted it in Substack's editor. Figured, why not automate this? So I built a simple utility. Everything happens in your browser with the `marked` library.

Most important feature for me is converting from ASCII to "fancy" quotes and apostrophes, which Substack inserts automatically in its editor. Some more advanced features are probably broken, because Substack's editor is a bit wonky, but the basic stuff all works. Give it a try!
