Splotch can automatically detect processes, workflows, and user journeys in your Google Docs™ and convert them into flowchart diagrams. If you want to convert a process that Splotch might have missed, you can simply copy/paste text and trigger a diagram generation manually. Once you're satisfied with the diagram, Splotch will insert each diagram back into your Google Docs™.
