Convai NPC AI Engine v4.6.1 Updated on the Unity Asset Store
Convai's Unity Asset Store package, “NPC AI Engine - Dialog, actions, voice and lipsync,” was updated to version 4.6.1 on September 29, 2026. The free Behavior AI tool is listed for NPC dialogue, actions, voice, and lipsync, with related terms including speech to text, AI NPC, ChatGPT, LipSync, and Generative AI. For AI characters, it signals continued tooling support for game NPCs that can speak, act, and animate through a unified Unity workflow.

Bringing dialogue, actions, voice, and lipsync into one NPC tool matters for implementation. I see this kind of update helping smaller teams build AI characters with less glue work.
