What Sudowrite is
Sudowrite is an AI writing partner built around tools for novelists and fiction writers. Its features include drafting, rewriting, describing, expanding, feedback, brainstorming, and AI chat for fiction. Story Bible takes a project from an idea and outline into chapters and drafts, while helping keep a series consistent. Sudowrite says it draws on Claude, open-source, in-house fiction models including Muse, and models created by OpenAI. Writers can browse a directory of more than 1,000 plugins or create their own without code. Writing is supported in almost any language, although some features may switch to English when Sudowrite is unsure. The service has web access and companion apps for iOS and Android; some capabilities are unavailable on mobile, including creating Visualize images, and series management requires the web app. Sudowrite says it does not use user writing to train its or OpenAI’s models and claims no rights over submitted or generated content. A free trial is available, but there is no free plan. Hobby & Student costs $10 a month.
