Convai is an advanced AI platform that allows developers to create real-time, interactive non-player characters (NPCs) for games, simulations, and virtual environments. By integrating natural language understanding, memory, and voice output, Convai enables characters to hold context-aware conversations with players or users—adding depth, realism, and personality to digital worlds.

Designed for game developers, metaverse creators, educators, and simulation designers, Convai removes the need for manually scripting thousands of lines of dialogue. Instead, it leverages powerful AI models to generate meaningful, responsive interactions in real-time.


Features

Real-Time Voice Interaction
Characters can speak and respond to users via microphone input using high-quality speech recognition and voice synthesis.

Context-Aware Conversation
NPCs remember context, react appropriately to player input, and hold multi-turn conversations with coherence.

Personality and Backstory Engine
Each character can be assigned unique attributes like profession, background, goals, and personality traits to drive personalized behavior.

Memory and Knowledge Integration
Characters can retain memories, recall past interactions, and access predefined or AI-generated knowledge bases.

3D Avatar Integration
Integrates with popular 3D engines (e.g., Unity, Unreal Engine) and platforms like NVIDIA Omniverse to bring characters into immersive worlds.

Multimodal Embodiment
Characters can move, gesture, and visually react in sync with dialogue and user interactions.

Multi-Language Support
Offers multilingual interaction support for global deployment.

Cloud and Local Hosting Options
Flexibility to deploy Convai characters on the cloud or integrate locally within development environments.


How It Works

  1. Create a Character
    Use the Convai character builder to define your NPC’s name, appearance, voice, background, and knowledge.

  2. Add Personality and Objectives
    Define traits such as friendliness, formality, and motivations, or let AI generate them dynamically.

  3. Integrate with Game Engine
    Use SDKs or APIs to connect your character with Unity, Unreal Engine, or web-based platforms.

  4. Test Conversations
    Simulate dialogue with your NPC and refine how it responds to user prompts or mission events.

  5. Deploy and Iterate
    Launch characters in your virtual world, game, or metaverse platform with ongoing learning and memory retention.


Use Cases

Game Development Studios
