Scapple

Rough it Out
Ever scribbled ideas on a piece of paper and drawn lines between related thoughts? Then you already know what Scapple does. It’s a virtual sheet of paper that lets you make notes anywhere and connect them using lines or arrows.

Make Connections
Join up your thinking however you want. Scapple doesn’t force you to make connections—every note is equal, so it’s up to you which notes have connections and which don’t. You have complete freedom to experiment with how your ideas fit together.
