Build a Visual Branching Story Engine for Fiction Writers

1. 1

   Study where writers abandon existing tools

   The open-source authoring communities are full of half-finished branching novels; the abandonment points (unnavigable trees past thirty passages, state logic requiring code, no professional export) are the feature list, straight from the horse's forum.

2. 2

   Make the branch map the home

   A zoomable visual tree with prose editing in place, orphan-passage detection, and path highlighting keeps a two-hundred-node story navigable; the map is what writers screenshot, which is what markets the tool.

3. 3

   Abstract state into 'what the story remembers'

   Writers think in consequences, not variables: 'the reader lied in chapter one' should be settable and checkable in plain language, with the engine handling the bookkeeping; this abstraction is the product's core design problem and its moat.

4. 4

   Build playtesting as a first-class loop

   Shareable test links, reader path analytics (where readers quit, which branches starve), and inline beta-reader comments give the author the feedback layer serialized fiction writers already expect from their platforms.

5. 5

   Export like a professional tool

   Clean web publishing, standard interactive-fiction formats, and print-friendly linear exports of chosen paths keep authors' work portable; lock-in by format is the incumbent sin this tool should loudly not commit.

6. 6

   Price for working writers and grow in their guilds

   A monthly price in the ten-to-twenty range with a free small-story tier fits the market; interactive-fiction jams, writing communities, and the choice-game modding scenes are concentrated, vocal, and generous to tools that respect them.
