GraphStory: Collaborative Story Writing through Event-Based Narrative Editing
For writers and creative professionals, GraphStory addresses the lack of support for brainstorming and narrative exploration in existing AI writing assistants, offering a structured yet flexible tool for early-stage ideation.
GraphStory introduces a graph-based interactive system for collaborative story writing that helps writers organize plot points, explore alternative narrative branches, and validate story flows. In a user study with professional and semi-professional writers, it reduced the effort of organizing narrative structures and better supported creativity and exploration compared to standard AI-based writing workflows.
Story writing is a popular yet complex creative activity that requires organization of ideas and iterative exploration, particularly during early-stage ideation. While many AI-based writing assistants have been developed, existing approaches primarily focus on generating long-form coherent text and improving user controllability during text production, providing limited support for brainstorming, connecting ideas, and validating alternative narrative flows. We present GraphStory, an interactive writing support system that leverages a graph-based representation to provide a comprehensive view of narrative structure and facilitate ideation. The system enables users to organize and connect plot points, explore alternative branches, and validate evolving narratives through an integrated story generation workflow. It further provides a structured interface to support efficient iteration over multiple story paths. Results from a user study with professional and semi-professional writers show that GraphStory reduces the effort of organizing narrative structures and better supports creativity and exploration compared to normal AI-based writing workflows.
