What is Convai?
Convai is a platform for creating embodied conversational AI characters, most prominently game NPCs, that can perceive their environment and respond naturally through dialogue, synthesized voice, gestures, and contextually appropriate actions.
Rather than scripted branching dialogue, Convai characters use large language models combined with spatial intelligence, vision perception, and long-term memory so they can see and hear their surroundings, remember past interactions, and behave believably within a scene. js.
Beyond games, Convai is used for interactive training and role-play scenarios, brand ambassadors, and virtual world onboarding and engagement. It is aimed at game developers building living NPCs, learning and training providers, brands, and metaverse creators.
Strengths include the depth of embodiment with perception and memory, broad engine integration, and extensive language and voice coverage.
Drawbacks are that generative NPC dialogue requires careful guardrails to stay in character and within content boundaries, real-time conversational AI can add latency and cost, and integrating it well still takes development effort.
Convai offers a free tier to get started with paid plans that scale with usage and interaction volume.
Because conversational NPCs run in real time, developers should plan for the runtime cost and latency of live AI alongside the upfront integration work, and invest in defining character lore, boundaries, and content filters so the generative dialogue stays believable and appropriate within the game's world.
