What is Sudowrite?
AI writing assistant built specifically for fiction authorsSudowrite is a specialized AI writing assistant designed exclusively for fiction writers, from hobbyists working on their first novel to professional authors managing multiple series. Unlike general-purpose AI writing tools, Sudowrite is built around creative prose and storytelling, powered by Muse, a proprietary language model fine-tuned specifically on published novels and short stories. Because Muse was trained on actual literary fiction, its output feels more natural, nuanced, and stylistically aware than generic AI models, understanding subtext, tone, pacing, and narrative structure on a deeper level. The Story Engine, updated to version 3.0 in 2026, is Sudowrite's full novel generation feature that transforms a premise, characters, genre, and style preferences into a complete beat sheet outline, then expands each beat into full chapters. The Write feature acts as an intelligent autocomplete, analyzing existing content including characters, tone, and plot to suggest the next 300 words in the author's own style.
- +Purpose-built for fiction with Muse model trained on published novels and stories
- +Story Engine 3.0 generates complete novel outlines and chapter drafts
- +Rewrite tool offers specific creative goals like Show Not Tell and Inner Conflict
- โขNovel authors seeking to write faster without sacrificing creative quality
