So one of my favourite editors - Ulysses - just got Ghost integration. This is me checking it out.
It actually works beautifully. Go to “publish”, add your Ghost account if it’s not present, pick the style you want to publish in, and you’re done. You can even choose draft/published, or the date to publish on, which is way more than I expected.
If you use macOS - or iOS - go check it out. :-)
