I also use Monodraw, can only recommend with one caveat:
@Dear Monodraw developers, if you're reading this, please please please implement discarding text edit popups using ESC, it's been years and I still keep reaching for ESC every time I use Monodraw. I tried decompiling it to binary patch it, but unfortunately it messes up the update mechanism.
This is my most missed app since switching from Mac to Windows. This new kid on the block looks like a solid replacement, though! Will definitely be checking it out.
Right now you can just tell claude to generate an ascii diagrama, or even svg. I did a few days ago when I wanted to share a flow diagram of one particular flow in our app.
I used to love monodraw when I had a mac. My daily driver and work machine is Linux now, so I've been searching for a suitable replacement for a while now. This one is probably the best I've seen so far.
