Ever dreamed of creating NPCs that can truly converse, or game worlds that react dynamically to player questions? This guide shows you how to bring the power of a conversational AI like Gemini directly into your Construct 3 projects. A recent video inspired me to dust off this idea and create an updated guide.

I had explored AI integration in the past, but technologies evolve quickly. While earlier AI tools had their limits, today’s powerful models like Gemini have completely changed the game. The focus now is all on ChatBots like ChatGPT and Gemini; incredibly powerful tools, despite their limitations. Integrating these models into the Construct 3 canvas with JavaScript unlocks fascinating creative possibilities, from NPCs with dynamic personalities to procedurally generated quests and lore.

By the end of this guide, you won’t just connect to an API; you’ll have built a functional chat system with memory, ready to be integrated into your own games.
