Convai

Convai builds AI characters for games and virtual worlds that go beyond a simple scripted dialogue tree. Characters are built around specific roles and objectives with narrative-driven flow design, and can be given a multimodal knowledge bank so you can add documents directly to what a character knows. On top of that sit long-term memory, an emotional state system, defined personalities and backstories, and built-in guardrails meant to keep a character's behavior within bounds. Voice and perception are both well covered: Convai supports more than 65 languages and over 500 voices, and characters can use webcam-based or point-of-view vision, which is a distinctive feature not common among competitors in this category. Lipsync, facial animation, full embodied animations, and the ability to sequence complex actions round out how a character actually presents itself on screen. On integration, Convai is avoider-agnostic and supports major avatar systems, with engine support spanning Unreal Engine, Unity, and 3JS, plus a PlayCanvas tutorial. Deployment targets include websites, mobile apps, video games, VR and AR, and even physical-world applications, through open APIs and SDKs. Pricing is not listed with specific plan names on the main page, though a free starting tier and an enterprise sales contact option, including on-premises deployment, are both offered.

• Webcam and point-of-view vision is a distinctive feature that is uncommon among the other tools in this category

Cons
