What Sudowrite does
Sudowrite is an AI writing app built for fiction authors. It uses its own fiction-tuned model, Muse, to suggest the next few hundred words, add sensory description, expand rushed scenes, rewrite passages and give feedback on drafts. A Story Bible holds your characters, outline and chapter beats so the AI stays consistent across a novel. A plugin library adds extra tools such as simulated readers and screenplay conversion.
Best for

- Writers stuck on a scene or chapter
