Convai

Convai is a freemium AI platform in the AI Gaming category that lets developers build intelligent conversational NPCs with real-time voice, lip-sync, and contextual actions for games, VR/AR, and virtual worlds, with paid plans starting at $499/month. The platform represents a breakthrough in embodied artificial intelligence, enabling developers to create truly interactive characters that understand and respond to both verbal and visual input with unprecedented realism. Unlike traditional chatbots or scripted dialogue systems, Convai's characters perceive their environment through computer vision, maintain emotional states and long-term memory, and execute in-world actions triggered by natural conversation. The end-to-end pipeline covers automatic speech recognition, LLM-driven dialogue generation, text-to-speech synthesis across 500+ voices in 65+ languages, real-time lip-sync, and character animation — all accessible through native plugins for Unity, Unreal Engine, Roblox, and WebGL, as well as XR platforms including Meta Quest and Apple Vision Pro. Developers configure each character's personality, backstory, and domain knowledge through a visual dashboard and knowledge bank system that grounds responses in custom documents and lore. Convai's action graph lets characters perform meaningful gameplay actions — unlocking doors, transferring items, guiding players — based purely on conversational context rather than scripted triggers. With a generous free tier for prototyping, tiered paid plans for indie and studio-scale production, and custom enterprise contracts, Convai serves teams ranging from solo developers to AAA studios building the next generation of interactive entertainment and training simulations.
