MacTwee
MacTwee is an objective-c wrapper for Twee. It uses Sprite Kit for a visual view of story maps, so 10.9 Mavericks or higher is required. It uses Core Data for managing stories across multiple projects. It includes various features for editing passages within a story.
Twee is required to compile html files, and upon building a project MacTwee will ask you where you have a copy of Twee installed locally (you can also set this in preferences). A working copy of Twee is included in this Git. View the tweecode project here.
MacTwee also imports and exports twee source files (txt, tw, twee). View the format of twee source code files here.
