The same firm that made Scrivener, Literature and Latte, also made Scapple. You create your stuff in Scapple, then you compose it in Scrivener.
Scapple is a straightforward but practical tool that resembles the mind-mapping method of brainstorming. Here, you should outline your main idea—which is typically broad—and begin tying related concepts to it.
In the past, writers would accomplish this on paper and with a pencil. Scapple made the decision to digitize this way of thinking in order to make it simpler, more readily available, and even more effective.
The number of possible mind maps in Scapple is infinite. You may infinitely enlarge your “paper” or document by zooming out. Zooming in closer to a section you need Scapple and Scrivener work together seamlessly. To add your mind map to a Scrivener project, you don’t even need to export it. You can just drag the mindmap from Scapple into Scrivener if both programs are active.
Scapple is your best option if you want to speed up and systematize the idea-generation process.
