What is Sudowrite?
Sudowrite is one of the few AI writing tools designed exclusively for creative fiction authors. Founded by novelists and trained on literary fiction, it understands narrative craft in a way general-purpose AI tools do not replicate reliably. Core features address specific fiction writing challenges: Write generates the next story section; Rewrite presents multiple alternative versions; Describe generates sensory-rich scene descriptions; Brainstorm produces plot ideas, dialogue, and story twists. The Wormhole feature creates story continuations with unexpected plot developments. Feedback provides craft-oriented critique covering pacing, emotional resonance, and showing versus telling. The Canvas feature provides a long-form workspace maintaining story context across chapters.
How Sudowrite works
Sudowrite runs as writing assistant software built around text workflows. Users typically start with a prompt, upload, or connected data source, and the underlying model handles the heavy lifting before returning a result you can refine or export. It's available on web.
