Sudowrite is an AI writing tool purpose-built for fiction rather than marketing copy or generic chat. Its Story Bible takes a writer from a loose idea through outline, chapter beats and full first draft in their own voice. Write acts like autocomplete tuned to a manuscript's characters, tone and plot arc; Describe adds sensory detail; Expand fixes rushed pacing; Rewrite handles line-level revision; and Feedback gives five actionable notes without needing beta readers. Under the hood, Sudowrite routes requests across multiple models — Anthropic's Claude, OpenAI models, open-source models and its own in-house fiction model, Muse — picking whichever fits the task. A visual Canvas for plotting, a Brainstorm tool for names and twists, Visualize for character/world art, and a library of 1,000+ community plugins round out the toolkit. Sudowrite claims no ownership over anything written in or generated by the app and does not train on user writing.
