Convai: Pricing, Features & Best Use Cases

Our take: Choose Convai to add talking 3D characters or NPCs to a game, XR or web experience, starting on the free plan (100 interactions per month) and moving to a paid Creator plan when you need more interactions.

Main limitation: Creator plans cap monthly interactions, cloud-rendered minutes and active end users, so production use needs the higher tiers or Enterprise.

What is Convai, and how does it work?

Convai lets creators and developers build embodied AI characters that talk in natural language and act within 3D environments. Characters get a configurable mind, an avatar body, and can be deployed in custom scenes, with perception abilities for interacting with their surroundings. The platform offers a web Playground, no-code experiences such as Avatar Studio and Convai Sim, plugins for Unity and Unreal Engine, web plugins and a core API.
