DeepQuill is a desktop novel-writing app for organizing and drafting a long book on macOS or Windows. Writers can arrange scenes into story beats, track scene status and story arcs, and view tension and point of view. Its codex connects characters and places with manuscript mentions and maps relationships among story elements. Research notes and a diagramming canvas that links to story elements support planning alongside the manuscript. Optional AI analyzes existing writing for entities, relationships, structure, and character details; it does not write prose or suggestions. Local analysis runs on the writer’s computer in the background, but an initial analysis of a full-length novel may take hours depending on hardware. Projects are local by default. Optional sync encrypts projects on the device before upload, and DeepQuill says it does not keep the decryption key. The app imports Scrivener projects and Word, Markdown, HTML, and plain-text documents, and exports to Word, EPUB, FB2, or PDF. Open beta is free; licenses cost 9.99 USD per month, 39.99 USD per year, or 49.99 USD one-time for updates within the purchased major version. Licenses activate on up to three devices.
Who it is for
DeepQuill suits novelists who want drafting, story planning, research, and continuity tools in one desktop app. Writers seeking AI-generated prose or suggestions should note that its AI analyzes existing text instead.
