PlotEngine
An AI-powered writing companion for fiction writers.
Overview
PlotEngine is a cross-platform writing assistant built for fiction writers wrestling with long, complex narratives. The hard part of a novel isn't the prose — it's keeping a hundred-thousand-word world consistent. Who has the scar? Which town burned down in chapter 3? PlotEngine tracks all of it.
As you write, it automatically recognizes characters, locations, objects, and events, and surfaces them so you never lose the thread. A structured knowledge base stores profiles and worldbuilding details; an AI consistency checker flags plot holes and timeline contradictions across hundreds of pages.
Built with Flutter for a single codebase across desktop and mobile, with a distraction-free rich text editor, automatic saving, and full multi-language support (EN/ZH/FR).
