Overview

Protagona builds an AI character engine that powers dynamic, unscripted conversations for non-player characters in video games. The engine plugs into popular game development platforms like Unity and Unreal Engine, allowing NPCs to understand player speech or text in real time and reply with contextually aware, personality-driven dialogue generated by large language models. This enables emergent narratives where stories adapt to player input rather than following fixed dialogue trees. The product targets game studios on a business-to-business basis, letting them create more interactive and replayable games without the heavy cost of writing and recording large amounts of scripted dialogue. Protagona aims to broaden player agency and deepen immersion by delivering natural conversational experiences within existing game pipelines.
