Overview
Convai is a developer platform to build lifelike, voice-driven NPCs and virtual characters. Its SDKs for Unity, Unreal, and web add end-to-end speech (ASR/TTS), LLM reasoning, memory, perception, and action execution so characters can converse naturally, understand context, and perform in-world tasks. Convai provides tools like character creation, knowledge bases, NPC-to-NPC dialogue, lip-sync, and integrations for PlayCanvas and MR, enabling studios to ship interactive NPCs across games and XR experiences.
