I&#x27;m currently trying to make graphical explanations on how a software works and would like to make it look good.  6-8 months ago, I discovered an online app that was making it easy to create diagrams with a &quot;hand written feel&quot;.  However, I can&#x27;t find it anymore.<p>Is anyone here using that kind of software?  If not hand-written, what tool do you use to create graphical explanations, if any?
Ask HN: Which hand written diagram software do you use?
