Sudowrite is an AI writing tool built for fiction authors. It helps you brainstorm ideas, build outlines and characters, expand scenes, rewrite prose and get editorial feedback on novels and screenplays. There is a free trial, and plans start at $10 a month billed yearly.
What is Sudowrite?
Sudowrite is an AI writing partner designed for storytelling rather than marketing copy. It understands characters, plot and point of view, so it can continue a scene in your style, describe a setting with all five senses or suggest a twist when you are stuck.
Its Story Bible keeps track of your characters, world and outline so long projects stay consistent, and it can draft whole chapters from your beats. It runs on several AI models, including its own fiction models Muse and Ballad, and does not use your writing to train AI.
