Convai
FreemiumCraft and deploy conversational AI characters for virtual worlds, games, and XR experiences.
Convai is a platform for building embodied, conversational AI characters that live inside games, virtual worlds, and XR experiences. It combines speech recognition, language understanding, text-to-speech, vision perception, and animation pipelines so developers can create NPCs and avatars that hear, see, speak, gesture, and act in context. With browser-based no-code tools, game-engine plugins for Unreal Engine and Unity, and open APIs, Convai serves creators and developers who want to add lifelike, interactive characters without assembling the full AI stack themselves.
What is it
A platform for crafting and deploying 3D AI characters and virtual humans with real-time voice, text, vision, and action capabilities.
What it can do
Generate characters with backstories and knowledge banks, power open-ended voice or text conversations, add lip-sync and body animations, enable scene perception, and trigger in-experience actions through game-engine plugins and APIs.
Who is it for
Game developers, XR creators, training-simulation builders, and brands that need interactive NPCs, virtual ambassadors, or guided avatars in 3D environments.
Key Features
AI Character Creation
Build characters in the browser with backstories, personalities, roles, and objectives using no-code tools that feed into runtime behavior.
Voice and Text Conversations
Support open-ended dialogue through both speech-to-text and text input, with AI-generated responses delivered via text-to-speech or on-screen text.
Multimodal Knowledge Bank
Upload documents and lore to ground character replies, keeping responses tied to defined world knowledge, product information, or training material.
Vision Perception
Give characters awareness through webcam or point-of-view vision so they can reference objects, users, or scenes during conversations.
Use Cases
AI NPCs in Video Games
Populate worlds with companions, enemies, or filler bots that respond dynamically to player voice or text instead of following rigid dialogue trees.
XR Training Simulations
Build role-playing scenarios where trainees practice conversations with realistic characters that react to speech, gestures, and environmental context.
Virtual Brand Ambassadors
Deploy 24/7 AI representatives on websites, kiosks, or virtual spaces to answer product questions and guide customers in a branded avatar form.
Social Virtual Worlds
Add lifelike AI inhabitants that onboard new users, drive engagement, and personalize social experiences in shared 3D environments.
