Convai

Convai is a conversational and agentic AI infrastructure platform built specifically for virtual worlds, enabling developers to create lifelike 3D AI characters that see, hear, and respond with human-like dialogue, voice, gestures, and contextually appropriate actions. Founded on the belief that AI needs embodiment and spatial intelligence to achieve deeper understanding, Convai lets creators craft a character's "mind" first, embody it within an avatar, and deploy it into a custom environment, whether that's a game, an XR training simulation, a website, or a social virtual world.

The platform centers on a set of core capabilities: role-playing characters with defined roles and objectives, a multimodal knowledge bank for uploading documents that inform what a character knows, narrative-driven custom conversation flows, and multilingual support across 65+ languages and 500+ voices. Convai characters can perceive their surroundings through webcam-based or point-of-view vision, respond with high-quality lip sync and facial animation, and execute complex actions through sequenced animations, all while supporting long-term memory so characters remember past interactions. For developers, Convai offers deep integrations with Unity, Unreal Engine, and PlayCanvas via official plugins, plus open APIs, SDKs, and an MCP server, and it remains avatar- and platform-agnostic, deploying across websites, mobile apps, video games, VR, AR, and even physical-world installations.

Convai serves three primary use cases: Learning & Training, where interactive role-playing AI characters power immersive corporate and educational simulations; Brand Representative, where AI brand ambassadors handle customer engagement 24/7; and Social Virtual Worlds, where AI companions improve onboarding, retention, and personalization in games and metaverse experiences. Built by engineers with backgrounds at Google, Nvidia, and Amazon, Convai is enterprise-ready with data and cloud security guarantees, AI safety guardrails, ISO 27001 alignment, and on-premises deployment options, making it a strong fit for game studios, XR developers, and brands building interactive AI-driven character experiences at scale.

Convai's Creator module offers a Free tier ($0/month) for prototyping with a limited daily interaction quota, followed by paid tiers: Indie Dev at roughly $29/month, Professional at roughly $99/month, Scale at roughly $499/month, and Business at roughly $1,199/month, each increasing interaction quotas, character concurrency, and knowledge bank size. Beyond the Creator module, Convai offers an Enterprise module with fully custom pricing for large-scale or specialized deployments, along with Partner plans that operate on a revenue-sharing model with minimal upfront cost. Convai states its per-interaction pricing is designed to undercut the combined market rate of separately licensing speech-to-text, LLM, and text-to-speech services.
