Sudowrite

Sudowrite is an AI writing tool built for fiction writers and novelists. It combines drafting, revision, planning, and chat features in a web editor, and the company also offers Muse, an AI model it describes as built just for fiction.

What It Is

Sudowrite is a web-based writing environment where authors work on novels and stories with AI assistance. According to its FAQ, it uses dozens of models, including Anthropic's Claude models, open source models, OpenAI models, and in-house fiction models such as Muse, paired with proprietary pre- and post-processing. The FAQ states that user writing is not used to train AI models and that the company claims no rights over what users write or generate.

Drafting and Revision Workflow

• Story Bible guides a writer from idea to outline to chapter beats to prose in the writer's style.
• Write analyzes characters, tone, and plot arc and suggests the next 300 words, offering options.
• Expand builds out rushed scenes, and Describe adds sensory detail.
• Rewrite revises text following the writer's direction, and Feedback gives five actionable areas for improvement.
• A word-finding tool and a Chat feature built for novelists support line-level editing.

Planning Tools

Canvas suggests alternate plot points, character secrets, and twists and collects references in one place. Brainstorm generates names, magic items, and titles, learning from the ideas users favor. Visualize generates art from character sheets and worldbuilding descriptions.

Plugins and Free Tools

Plugins offer 1,000+ extensions, such as simulating readers, talking to characters, or converting a novel to a screenplay, and users can build their own. Sudowrite also runs free microsites, such as a story generator that produces five genre-specific plots with 3-act summaries without requiring an account.

Language and Account Notes

The FAQ says users can write in almost any language, though some features may fall back to English. If a subscription is canceled, projects stay accessible, but AI features require a paid plan.
