Sudowrite is an AI writing tool designed exclusively for fiction. Where many general AI writing assistants target marketing copy or business documents, Sudowrite's features are built around the specific mechanics of storytelling: plot structure, character consistency, sensory description, and prose style.
Founded in 2020 by James Yu (previously a co-founder of Parse, acquired by Facebook) and Amit Gupta, Sudowrite is headquartered in San Francisco and has grown to roughly 15 to 20 employees as of 2026, serving a global community of self-published and traditionally published authors.
Story Engine walks writers through outlining a novel, generating chapter-by-chapter beats and character arcs from a premise. Describe expands a sentence into richer sensory detail across sight, sound, touch, taste, and smell.
Rewrite offers multiple style variations of a passage (such as more tense, more vivid, or more concise), while Brainstorm generates plot twists, character names, settings, and other story elements on demand.
A canvas-based story editor lets authors organize chapters, character sheets, and story bible details in one workspace, and the Professional tier adds AI feedback on drafts.
Sudowrite uses a credit-based subscription model with three consumer tiers plus a custom Enterprise plan. Hobby and Student costs 10 dollars a month for 225,000 credits, Professional costs 22 dollars a month for 450,000 credits, and Max costs 44 dollars a month for 2,000,000 credits with a 12-month rollover on unused credits. Annual billing offers a discount versus paying monthly, and a one-time free trial with roughly 10,000 credits is available with no credit card required.
