I use Monodraw[1] on my Mac, I really like it because it's ascii rather than image or vector based which makes including the diagrams in markdown really easy.
It also has a really simple UI that allows me to quickly map out my thoughts so I use it for a lot of things.
This is actually pretty nice. Sometimes to explain stuff and flows, I draw shitty graphics in emails by using a combination of ASCII characters. This is like the pro version of that.
