Tsukue is a local-first macOS writing app for novels, books, and long projects. Instead of one endless document and one crowded sidebar, it gives you four spatial desks, inline literary feedback, a timeline, character detection, compile, and encrypted backups.
Many Mac writing apps still revolve around a single manuscript pane. Tsukue is built around smaller units of work. Pages can be drafted, finalized, moved into stacks, or reviewed in context. The Binder organizes everything in a nestable hierarchy of books, folders, and scenes.
Draft in pages, group them in stacks, and organize books in a nestable folder hierarchy. Focus Mode for distraction-free writing. Typewriter sounds included.
12 style checks, readability heatmap, and a written editorial report in three voices: mentor, editor, or cynic. Character analysis with presence tracking and Chekhov Check.
Freeform pinboard with cards, images, and connections. Pin ideas close to the manuscript without switching apps.
Arrange scenes chronologically on a freeform canvas. Track character threads. Conflict detection catches temporal impossibilities.
Automatic character and place detection. Alias clustering. POV and narrator assignment per folder or scene.
Merge entire books into PDF, DOCX, or Markdown. Save text versions per scene with diff view for tracking changes.
