About
Sudowrite is the go-to AI writing partner for fiction writers, praised by bestselling authors and major publications like The New Yorker, The New York Times, and The Verge. Unlike general-purpose AI tools, Sudowrite is purpose-built for storytelling, powered by its proprietary Muse 1.5 model that understands character arcs, tone, pacing, and plot structure. The platform offers a comprehensive suite of writing tools: **Story Bible** guides writers step-by-step from initial idea through outline, chapter beats, and thousands of words written in their own style. **Write** acts as an intelligent autocomplete that analyzes your characters, tone, and plot arc to suggest the next 300 words in your voice. **Expand** builds out rushed scenes to improve pacing, while **Describe** generates vivid, story-appropriate descriptions that paint mental pictures without slowing the narrative. For revision, **Rewrite** serves as a flexible, ego-free editing buddy that takes direction and rewrites sentences or passages on demand. The **Feedback** feature provides three actionable improvement areas based on your full manuscript. A magic AI canvas lets writers brainstorm plot points, character arcs, and themes visually. Sudowrite is ideal for novelists, short story writers, screenwriters, and anyone tackling long-form fiction who wants to move from blank page to finished draft faster—without sacrificing their unique voice.
