Sudowrite - 2026 Pricing, Features, Reviews & Alternatives

Sudowrite is a cloud-based and mobile AI writing assistant built exclusively for fiction authors, available via web app and native iOS and Android apps. It covers the full fiction writing workflow — from initial brainstorming and outlining through chapter drafting, scene expansion, prose rewriting, and manuscript organization. Three subscription tiers (Hobby and Student, Professional, and Enterprise) serve casual writers, self-published novelists, screenwriters, NaNoWriMo participants, and high-output professional authors, with all features available across every tier and plans differing only by monthly credit volume.

Core writing tools include Write (story continuation in Auto or Guided modes, reading up to 20,000 words of prior text plus 25 linked chapter documents), Draft (full chapter generation of 3,000–5,000+ words from structured scene outlines), First Draft (800–1,000+ word scene generation from notes), Expand, Describe (rich sensory detail generation across all five senses), Rewrite, Brainstorm (ideas for names, plot twists, character traits, and worldbuilding), and Feedback (five actionable improvement areas per passage). The Story Bible functions as a structured project hub — covering genre, style, synopsis, characters, and outline — keeping the AI informed across the full manuscript. Canvas provides a visual outlining tool for mapping plot points, character arcs, and story structure. The in-editor Chat assistant has full project context awareness and can create and edit documents, leave comments, update the Story Bible, and execute multi-step rewrites. Community-built Plugins extend core functionality further.

Sudowrite's AI layer is powered by Muse, a proprietary fiction-trained model, alongside integrated third-party models including Claude models by Anthropic, OpenAI models, and open-source models. The Style Examples feature calibrates Muse to a writer's own prose samples, aligning generated output with the author's cadence and vocabulary. The Brainstorm feature refines suggestions based on user feedback signals. User writing data is not used to train any models, and no rights are claimed over user-created or AI-generated content.
