Sudowrite

Sudowrite is an AI writing assistant built specifically for fiction authors, novelists, and screenwriters rather than general-purpose content. At its core is Muse, a proprietary language model the company says was trained only on fiction instead of general web text, aimed at handling scene structure, pacing, and dialogue that reads as human rather than generic. The platform combines several tools around a Story Bible feature that guides writers through outlining, character development, and chapter structuring. Write generates story continuations that match a writer's existing voice when they get stuck, Expand lengthens rushed scenes for better pacing, Describe adds sensory detail, and Rewrite offers flexible revision options. A Chat interface lets writers talk through plot and character decisions, Canvas provides a collaborative space for mapping plot points and arcs, and Brainstorm generates names, titles, and worldbuilding ideas. Visualize turns character and setting descriptions into artwork, and a plugin marketplace with over 1,000 community and custom tools extends the core feature set. Sudowrite runs as a web-based editor and is aimed at writers working on novels, short stories, and scripts who want AI assistance built into their drafting process. Plans start at $10 a month after a free trial that requires no credit card, and the company reports more than 22,000 writers use the platform.
