FreemiumactiveVerifiedGame DesignCoding and Scripting
Overview
Convai is a developer platform for building 3D AI NPCs with natural language conversation, multimodal perception (vision, hearing), lip-syncing, and embodied animations. NPCs powered by Convai can see the game world through camera input, perform complex action sequences based on player commands, maintain persistent knowledge bases (upload lore documents), and converse in 65+ languages with 500+ voice options. Unity and Unreal Engine plugins are available; characters support MetaHuman, Daz3D, ReadyPlayerMe, and custom avatars.
Best For
- RPG and open-world devs who want NPCs that respond to player actions and see the world
- Teams building immersive XR or simulation training experiences with dialogue
- Devs who need multilingual NPC voice without building a TTS pipeline from scratch
