A Novel Idea is a tool for plotting your story and recording bursts of inspiration. Use its simple interface to create your characters, locations, scenes, and novels and then link them together to create your story's plot. Use the Idea feature to quickly jot down your creative sparks and link them to your story elements. Arrange your scenes by dragging and dropping them into place. Add scene goals and objectives for each character.
