macOS writing app

A writing app for Mac that treats drafting and revision as different jobs.

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.

What makes Tsukue useful

Built for long-form writing on Mac.

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.
