About pbrain studios

Independent development studio of Paige Yoo. I build AI-driven games, creative applications, and experimental projects at the intersection of code and storytelling.

pbrain studios is both a portfolio and a sandbox for new ideas. My work spans game development, artificial intelligence, and interactive media, from designing 16-bit inspired RPGs with dynamic characters to building production-ready web applications and voice synthesis tools.

I approach each project with a focus on technical precision, creative design, and user experience. Whether I am deploying scalable backends, fine-tuning language models, or crafting narrative systems, my goal is to combine engineering with storytelling in ways that feel alive and engaging.

Core Focus Areas

Flagship Projects

Foil Engine

An AI-powered platform for building interactive NPCs. Define character personas and conversation flows as state machines. The AI generates natural language while staying in character. Includes a visual editor, REST API, and SDKs for Python, TypeScript, and Unity.
