Designing interactive story systems: When narrative becomes a software problem

Interactive storytelling is often treated as a writing problem. In practice, it quickly becomes a systems design challenge.

While building Choose Your Fate, a platform for creating and reading interactive stories, we came to understand what makes the medium genuinely challenging: branching paths that create contradictions across a story, pacing that breaks down as choices multiply, reader agency that feels real but requires careful construction to actually be meaningful. The structure holding the story together turns out to be as demanding as the story itself.

This talk is about what we learned treating narrative as an engineering and craft problem.

We'll walk through how stories behave like graph systems once you introduce branching, why complexity grows faster than it looks, and how specific structural patterns (diverging, converging, looping, state-persistent) can keep a story coherent while preserving genuine reader agency. A recurring pattern in existing systems is flat choices that carry no real consequence, or meaningful decisions locked behind a monetization layer rather than a narrative one.

We'll look at the product side too: what it takes to build tools for writers who don't think in systems, and how you design interfaces that support system-level thinking without asking creators to become engineers.

We'll also cover how AI fits in this creative space without alienating the creators: not as a story generator, but as something closer to a structural editor that can flag pacing problems and suggest where choices belong.

Attendees will leave with:
- A clearer mental model for why interactive narratives break down and how to prevent it
- Structural patterns that balance branching complexity with story coherence
- Design lessons from building a creator platform for interactive storytelling
- A realistic view of where AI helps in creative tools and where it doesn't
