i'm surprised no one has mentioned Marked 2 from Brett Terpstra - http://marked2app.com

it's a Markdown document viewer that displays changes as you make them in your favorite editor (ST3 in my case).

what puts it over the top for me is its perfect rendering of Github Flavored Markdown.

Oooh, nice find. I almost didn't learn about this because it was so far down. This fits my workflow perfectly...
