ChapterMuse is a desktop writing application for novelists and other fiction writers. It brings manuscript drafting, chapter and scene organization, character profiles, plot planning, and worldbuilding into one workspace. The Studio edition adds tools for organizing locations, factions, and items, along with book formatting and EPUB export. Core writing features run offline, and manuscripts are stored on the user's computer; optional AI tools and cloud services are offered separately. ChapterMuse is available for Windows through the Microsoft Store, with Light, Writer, and Studio editions sold as one-time licenses for the purchased major version and updates within that version. A 30-day trial is offered, and a Mac edition is planned. The software is intended for novelists, independent authors, and writers who want to plan and manage fiction projects alongside their drafts.
