Your Story, Your Choices: An AI-Powered Adventure with Node Story

This is a submission for the Google AI Studio Multimodal Challenge

What I Built

I created Node Story, an AI-powered storytelling platform that transforms users into the main character of their own adventure.
Instead of passively reading a story, players decide what happens next. Every choice branches into a new path, and the AI dynamically generates the consequences, shaping how the journey unfolds and even how it all ends.
The idea was to make storytelling interactive, personal, and creative, so no two adventures are ever the same. Each user writes their own legend simply by making selections along the way.

How I Used Google AI Studio

I used Google AI Studio with the Gemini 2.5 Flash model as the creative engine for Node Story. It generates narrative passages that stay consistent with the user’s previous choices. It adapts tone and pacing depending on the direction the player takes.It allows for quick prototyping, so I could focus on polishing the branching structure and UI.
Google AI Studio made it easy to blend AI’s storytelling ability with an interactive format where users feel in control of the narrative.

Multimodal Features

Node Story leverages multimodal prompting by combining:

• User-provided input (their choices at each decision point)
• Contextual narrative prompts (to keep the story world coherent) This means the AI isn’t just telling a story to the user—it’s telling a story with the user. The experience is unique because the ending is never predetermined; it emerges naturally from the path the user carves through their choices. Future updates could expand this with visuals—like AI-generated scene art or character portraits—making the experience even more immersive. I’d love to hear your thoughts!
• Do you find this kind of interactive, AI-powered storytelling helpful or inspiring?
• How do you imagine using something like this; fun adventures, learning tools, creative writing practice?
• What features would you like to see next (images, character art, new genres)? Feel free to drop your feedback or questions in the comments. I’ll be happy to chat and improve Node Story further!
