Convai review

Convai is the most game-focused platform here for characters players can talk to. You build a character in the browser with a backstory, personality, knowledge bank, narrative design and a list of actions it can perform, choose from more than 500 voices and 60+ languages, then drop it into a scene with the Unity or Unreal Engine plugin or a 3JS integration. Characters can use vision through the API to perceive their surroundings, and paid plans add long-term memory between sessions and character versioning. Pricing is tied to interactions and players: the free plan allows 100 interactions a month for one end user, and Indie Dev costs $29 a month, or $22 billed yearly, for 3,000 interactions and 75 monthly active end users. That suits prototypes and demos, but a released game with many players needs the Scale or Business plans or an enterprise contract. Enterprise adds on-prem deployment and SLAs.
