Sudowrite

Tool Overview

Sudowrite is a purpose-built AI writing tool for creative writers, novelists, screenwriters, and storytellers that goes far beyond grammar correction to help with plot development, character creation, worldbuilding, and narrative structure. Unlike general-purpose AI writing assistants optimised for business communication, Sudowrite understands narrative arcs, pacing, point of view, and genre conventions — offering specialised tools such as the Story Engine for generating chapters from a premise, Beat Sheets for plotting novel structures, and Expand/Describe modes for enriching existing prose with sensory detail and emotional depth. The platform includes a custom-trained AI model fine-tuned on literary fiction, genre fiction, and screenplay formats, providing suggestions that maintain voice consistency across long-form narratives. Stephen King's newsletter praised Sudowrite, and the platform has been adopted by thousands of published authors for overcoming writer's block, expanding short stories into novels, and polishing manuscripts before submission. Sudowrite also offers a suite of feedback tools including pacing analysis, dialogue tagging, and show-versus-tell detection that help authors identify structural weaknesses in their drafts.
