What Sudowrite is
Sudowrite is an AI writing partner focused on fiction, with tools for drafting, revising, describing, expanding, feedback, brainstorming, and AI chat. Its Story Bible helps writers move from an idea and outline into chapters and draft writing while maintaining continuity across a series. The service says it uses Claude models, open-source models, its own fiction models including Muse, and models created by OpenAI. Writers can use more than 1,000 plugins, and Sudowrite says users can also make plugins without code. It supports writing in almost any language, though some features may switch to English when the system is unsure. Companion apps are available for iOS and Android, but some capabilities differ from the web version. Sudowrite says it does not use user writing to train its or OpenAI's models and claims no rights over submitted or generated content.
