Bookwiz

Bookwiz is an AI-powered co-writing tool designed for authors who need to maintain consistency across complex narratives. It goes beyond generic AI chat by building a "Story Bible" that stores characters, locations, magic systems, and plot threads, then uses that context to inform every AI-generated suggestion. This ensures characters stay in character, world-building remains coherent, and plot details stay consistent across hundreds of pages. The platform includes a file explorer for organizing chapters, version control to track changes, and context-aware editing features that allow writers to ask for improvements to specific scenes. Bookwiz is built for serious authors working on fantasy epics, sci-fi sagas, mystery series, or multi-volume projects where continuity is critical. It supports multiple AI models for generating and refining text, and is used by over 55,000 writers.
