Any of you using Deckset or Slideas these days?

I’m a big Keynote for for presentations with a long lead time. However, I was asked to give an impromptu presentation last next week and I was thinking of revisiting Deckset, for which I purchased a license several years ago and used on a few occasions at the time. A similar app is Slideas which @terpstra referenced recently.

Both of these automatically generate slides from markdown notes.

Wondering if any of you use these apps regularly, and what your thoughts are.

I’m wondering how your experience was with Slideas? …or if anyone else has some experience to share?
