I'm looking for something like ReText, but for AsciiDoc.

The closest I have found is this relatively complex solution (or here) involving Ruby, guard, guard-shell, rb-inotify, asciidoctor, Epiphany (or another browser with LiveReload).

I'll do all that if it is the best option. But I was looking for just a simple solution, along the lines of a ReText for AsciiDoc.

I also heard that O'Reilly has some tools (e.g., the Atlas wiki interface), but I'm not submitting my documents to O'Reilly. (Atlas looks cool and I'd consider using it if I could do so privately.)

Anyone have another suggestion?
