What Sudowrite is
Sudowrite is an AI writing partner made by writers for fiction. Instead of a generic chatbot, it offers tools tuned to storytelling problems: flat description, rushed pacing, sentences you’ve rewritten 100 times, plot holes and blank pages.

The centerpiece is Story Bible, which guides you from an idea to an outline, to chapter beats, to thousands of words written in your style.
