The best AI partner for novelists and prose authors

Sudowrite is the only AI service created exclusively for literary prose: the platform helps novelists navigate the path from raw idea to complete manuscript, preserving the author's voice and genre nuances. Featured in NYT, The New Yorker, NPR, and WIRED as the best tool for book writing.

Key Fact: In blind tests, users preferred the Muse 1.5 model twice as often as Claude 3.7 Sonnet for literary prose, due to its proper pacing and genre conventions.

Key Features of Sudowrite

  • Muse 1.5 - a proprietary language model trained on published novels and short stories; it understands dialogue rhythm, scene blocking, and genre conventions better than general LLMs.
  • Story Engine 3.0 - takes a brainstorming dump, genre, style, and character list, then autonomously generates chapter-by-chapter beatsheets and full prose with narrative arcs.
  • Story Bible - centralized database of characters, world-building, and universe rules; allows uploading a 2000-word sample to adapt the generation to the author's voice.
  • Describe - enriches prose with all five senses: smells, textures, sounds, tastes, and visual images; supports Sensory Rewrite in the spirit of a specific author or period style.
  • Canvas 2.0 - an infinite spatial board for brainstorming: AI agents "read" the proximity of cards and generate connections between characters and plot twists.
  • Multi-Model Orchestration - choose between Muse, Claude, GPT-4, GPT-4o mini, DeepSeek, and Goliath for different tasks without leaving the interface; Goliath is for less censored content.
  • Shrink Ray and Plugins - Shrink Ray compresses chapters into brief beatsheets for pacing analysis; JavaScript plugin ecosystem adds micro-tasks: cliché removal, plot twist generation, magic systems.

Sudowrite vs Competitors

ChatGPT ($20/month) - a powerful universal tool but lacks Story Bible, Story Engine, and Describe. Working on an 80,000-word novel requires manual context management, whereas the service stores it centrally.

NovelAI ($10/month) excels in content freedom and anime illustration generation, but falls short in structured long-form workflow. Novelcrafter attracts heavy users with a low subscription plus its own API key - potentially cheaper on large volumes, but "out of the box," it is inferior in prose tools quality.

Lifehack: For uncensored scenes, switch to the Goliath model in Multi-Model Orchestration settings - it's based on open-source and has minimal content restrictions.

Use Cases

Drafting a Novel from Scratch
Story Engine 3.0 converts a braindump into a chapter-by-chapter beatsheet, then unfolds into full chapters. Typical usage - 600,000-1.5 million credits for a full manuscript.
Serial Web Fiction
Wattpad and Royal Road authors: Canvas for planning 5 chapters on Monday → draft 15,000 words by Tuesday → polish → publish on Thursday.
Enriching "Flat" Prose
Describe adds specific sensory details - the smell of burnt coffee, the texture of worn leather - instead of generic epithets.
Multi-Volume Series
Story Bible retains characters, locations, and world rules between books - AI automatically takes the knowledge base into account in each new session.
