What is SudoWrite?

Sudowrite is an AI writing tool designed with fiction and other creative works in mind. Instead of a typical productivity app, science fiction authors built it to be more of a writing partner, encouraging collaboration and idea generation. Unlike many AI tools geared for short marketing content, Sudowrite assists novelists and short story writers with the deeper aspects of writing: composing extended scenes, monitoring characters, and developing compelling story arcs. Sudowrite uses a combination of general-purpose AI models (GPT-5 and Claude 4. 1) alongside Muse 1. 5, its proprietary fiction-optimized model. It gives you a platform that writes, helps you build your world, keeps your story on track, and manages your whole manuscript.

Key Features

  • Feedback: Highlights three specific areas in any draft that can be improved.
