Learn moreFiction-focused AI writing partner for drafting, revising and planning novels

Sudowrite is a fiction-focused AI writing app with tools for outlining, drafting, expanding, rewriting and feedback, plus a fiction model called Muse and a plugin library. It targets novelists and fan fiction writers.
Sudowrite is a web-based writing environment built specifically for fiction. Instead of a general chatbot, it offers a set of tools that follow the stages of writing a novel: planning, drafting, expanding, revising and polishing. It is aimed at novelists, fan fiction authors, screenwriters and hobbyists who want a collaborator that can get past a stalled scene without taking over the work. In practice, the app is organized around projects that hold drafts and chapters. Story Bible walks a writer from an initial idea to an outline, chapter beats and prose written in the author's own style. Write proposes the next stretch of text, about 300 words, based on the characters, tone and plot arc it has analyzed, and offers several options. Expand builds out scenes that feel rushed, while Describe adds sensory detail. On the revision side, Rewrite takes direction on a passage, Feedback returns five areas to improve, and a word finder suggests alternatives in a couple of clicks. Canvas, Brainstorm and Visualize cover the planning side with plot points, names, titles and generated art from character and worldbuilding descriptions. The company also offers a chat feature tuned for novelists, a fiction model called Muse (version 1.5 is highlighted), and a plugin system with more than a thousand community and official add-ons. Plugins can simulate readers, let a writer talk to their characters or convert a novel to a screenplay, and users can build their own. The interface includes eight themes, five dark modes and a full-screen focus mode. Among alternatives, Sudowrite sits closer to dedicated fiction tools than to general assistants or marketing copy generators. Its trade-off is specialization: the feature set suits narrative work far better than business writing. A trial is available without a credit card, and a set of free single-purpose generators on the site lets visitors test the approach before committing to the editor.
