Runtime AI Chatbot Integrator (+TTS)

Advanced AI Integration for Unreal Engine

The Runtime AI Chatbot Integrator (+TTS) is a comprehensive solution for developers looking to add intelligent conversation to their projects. This tool allows you to transform games and applications with powerful AI capabilities and natural speech. Consequently, you can access the most advanced language models available today through simple Blueprint nodes. The plugin is designed to work without the need for complex C++ coding.

Comprehensive AI Chatbot Support

This plugin connects to a wide variety of official APIs for top-tier AI providers. Supported platforms include OpenAI, Anthropic’s Claude, Google’s Gemini, xAI’s Grok, and DeepSeek. Furthermore, the developer has included support for Ollama, enabling access to models like llama3.2 and mistral. You can choose between receiving complete text responses or real-time streaming. This flexibility ensures that your project can handle data chunk by chunk for a more responsive feel.

The Runtime AI Chatbot Integrator (+TTS) supports the latest models, including GPT-5.1, Claude 4.5 Sonnet, and Gemini 2.5 Pro. It also features DeepSeek Reasoner, which provides dedicated reasoning output for complex logic. Therefore, developers can implement high-level intelligence into their gameplay mechanics or virtual assistants with ease.

High-Quality Text-to-Speech Capabilities

In addition to text chat, the plugin offers robust text-to-speech (TTS) functionality. It integrates directly with OpenAI, ElevenLabs, Google Cloud, and Azure. For instance, you can use ElevenLabs for dynamic text streaming, which appends text incrementally during synthesis. This is particularly suitable for real-time AI chat responses. Moreover, the system includes voice discovery features for services like Google Cloud and Azure to help you find the perfect tone for your characters.

Note that the images and examples for text-to-speech were created using the Runtime Audio Importer plugin. To follow those specific examples, you will need to install that additional plugin. However, you are free to implement your own audio handling solution if preferred. For standard text-to-text functionality, the additional importer is not required.

Cross-Platform and Blueprint Ready

The Runtime AI Chatbot Integrator (+TTS) is built for versatility across multiple environments. It works on all platforms supported by Unreal Engine, including Windows, Mac, Linux, Android, and iOS. Additionally, it is compatible with VR platforms like Meta Quest. Authentication is simplified through an easy API key management system for all integrated services.

This resource is perfect for creating interactive NPCs with intelligent voices and personalities. It also serves as an excellent tool for in-game guides, educational applications, and creative content generation. By using the Runtime AI Chatbot Integrator (+TTS), you can build immersive, AI-driven experiences that respond naturally to player input.
