OpusWriter

OpusWriter is a complete fiction-writing studio in one desktop app, combining story planning, worldbuilding, writing, editing, series management, and book formatting. Move from your first idea to a book ready for publication in one workspace, with your manuscript, research, and story details connected throughout the process.

Plan your story with outlines, plot development tools, character profiles, settings, research, and worldbuilding notes. Explore ideas on visual boards, organize events with timelines, and connect chapter outlines to the characters, places, and story elements they involve.

Write and organize your manuscript in chapters and folders, with planning and reference material available alongside your prose. Track writing goals and progress, capture ideas, and follow narrative promises from setup through payoff.

Revise with over 50 prose-analysis tools, covering everything from adverbs and filtering language to rhetorical devices. Compare the tension in your prose with the scene targets you set while outlining, and explore AI-assisted feedback and polishing while choosing which suggestions to apply. When working with an editor, round-trip Word documents to bring comments and tracked changes back into OpusWriter, keeping your manuscript and editorial feedback together.

Build individual novels or connected book series. Keep each book’s manuscript and planning material organized, share selected characters, settings, and worldbuilding through the Series Vault, and track story seeds that develop across multiple books.

Format your books for publication with customizable styles, chapter designs, and front and back matter. Export PDF files for print, EPUB files for eBooks, or Word documents for editing and collaboration, with Shunn manuscript formatting available for submissions.

Whether you’re outlining a first novel or developing a multi-book series, OpusWriter brings the work of planning, drafting, revising, and preparing your books for publication into one application.
