Description
Rune is a small, fast text editor for the Mac. One scratch file in iCloud Drive is shared by all your Macs: saved as you type, and edits from two Macs are merged, never overwritten. Plain-text paste, Sublime Text's colors and keys, and Find in History.

Could you build this?
Partial A basic macOS text editor is easy to code, but robust non-destructive multi-device file merging over iCloud Drive synchronization requires complex conflict handling.
What it would actually take: Requires a native macOS app built with Swift and AppKit/SwiftUI integrating deeply with NSFilePresenter and NSFileCoordinator. The hard part is implementing a reliable three-way merge or lightweight CRDT/OT engine that reconciles concurrent edits arriving asynchronously from iCloud Drive without locking the UI or corrupting plain text.
