✦ About
Gemini AI Toolkit is an Unreal Engine plugin that connects your project to Google Gemini — giving you access to AI text generation, image generation, and NPC conversations directly from Blueprints. No Python, no external tools, no C++ required.
Whether you're building AI-powered NPCs with unique personalities, generating images at runtime with NanoBanana, or adding an AI assistant to your game — this plugin handles it all with simple async Blueprint nodes.
Just add your Gemini API key and start creating.
✦ Features
▸ AI text generation — send prompts and get responses with a single async node
▸ AI image generation — create and transform images at runtime (powered by NanoBanana / Gemini)
