DeepQuill is a desktop novel-writing app for drafting and organizing a long book on macOS or Windows. Writers can arrange scenes into story beats, follow story arcs and scene status, and examine tension and point of view. Its codex connects characters and places with their manuscript mentions and maps relationships among story elements. Research notes and a diagramming canvas linked to story elements bring planning material alongside the manuscript. Optional AI analysis can identify entities, relationships, story structure, and character details in existing writing. It does not write prose or offer suggestions. Analysis can run locally in the background while work continues, though the first analysis of a full-length novel may take hours depending on the computer. Projects are saved locally by default. Google sign-in enables optional encrypted sync; DeepQuill says projects are encrypted on the device before upload and that it does not have the decryption key. The app imports Scrivener projects and Word, Markdown, HTML, and plain-text documents, and exports to Word, EPUB, FB2, PDF, TXT, or Google Docs. During the free beta, editing requires product analytics; session recordings mask on-screen words and hide images, and the maker says manuscript text is excluded.

DeepQuill suits novelists who want scene planning, continuity links, research notes, and manuscript work together in a desktop app. It may also suit writers who want optional analysis of existing text, provided they do not expect AI-written prose or suggestions.
