What it is
Sudowrite is an AI writing partner focused on fiction and tools for novelists. Its writing features include Write, Rewrite, Describe, Expand, Feedback, Brainstorm, and AI chat. Story Bible helps writers develop an idea and outline into chapters and drafts while supporting continuity across a series. Sudowrite says it uses Claude models, open-source models, its in-house fiction models including Muse, and models created by OpenAI. Writers can browse over 1,000 plugins, and the company says users can create plugins without code. The service supports writing in almost any language, though some features may fall back to English when it is unsure. Web access and companion apps for iOS and Android are available, but mobile lacks Visualize image creation and series management requires the web app. Sudowrite says it does not use user writing to train its own or OpenAI's AI models and claims no rights over entered or generated content. A free trial is available, but there is no free plan. The Hobby & Student plan costs $10 a month and includes 225,000 credits per month.
