FiveActs combines fast input with user comfort. FiveActs takes care of the formatting for you – just press the return key and FiveActs will show you the next possible steps in your script, creating a document that follows the standard script formatting structure, including fonts and indentations. Anyone familiar with screenplays will immediately understand the outline and find their way around the script. Of course, it's also possible to customize and adjust the script design to your own preferences.

Novels and Stories

FiveActs makes it very easy for you to write screenplays or plays. But FiveActs is also perfect for novels and other books. Design and develop your characters by using the sociograms to record all relationships, feelings, and tensions between them. Use the idea cards to sort smaller and larger ideas, and then use them to spin the thread of your story.

Instead of creating acts and scenes like in screenplays, FiveActs takes care of organizing chapters and sections for novels. The sidebar shows you the structure of your book and allows quick navigation. Characters and places in a story can be marked directly, so you'll always know at which points in your novel each character or place appears.
