Convai is a developer platform to build lifelike, voice-driven NPCs and virtual characters. Its SDKs for Unity, Unreal, and web add end-to-end speech (ASR/TTS), LLM reasoning, memory, perception, and action execution so characters can converse naturally, understand context, and perform in-world tasks. Convai provides tools like character creation, knowledge bases, NPC-to-NPC dialogue, lip-sync, and integrations for PlayCanvas and MR, enabling studios to ship interactive NPCs across games and XR experiences.

What the evidence says about Convai

Convai is a hosted platform and SDK suite for building conversational AI characters, NPCs, avatars, and virtual humans across games, web experiences, XR, kiosks, and simulations. It provides character configuration, knowledge, voice, actions, memory, APIs, and engine plugins; it is a character-agent development platform rather than one standalone assistant.

Verified capabilities

  • Character design and knowledge

    Creators can configure backstory, personality, languages, voices, knowledge banks, narrative elements, actions, versions, and conversation evaluation.[1], [4]

  • Real-time multimodal interaction

    The web SDK supports streamed voice and text, optional video and screen sharing, emotion and action signals, and blendshape queues for facial animation.[5]

  • Game and web integrations

    Official integrations cover Unity, Unreal Engine, PlayCanvas, the Convai Web SDK, and custom application APIs.[3]

Research coverageExact counts from this profile; bars are relative to the largest count shown.

Where it fits best

  • Game, XR, training, simulation, and web teams that need voice-first characters with personality, knowledge, actions, animation signals, and engine integration.[1], [3]

Buying and deployment notes

Convai has a Free plan with 100 monthly interactions and one concurrent character session. Monthly tiers start at $29 for Indie Dev, then $99 Professional, $499 Scale, and $1,199 Business; yearly billing lowers the advertised monthly equivalent, while Enterprise is custom-priced.[2]

Platforms: Web SDK, Unity, Unreal Engine, PlayCanvas, XR, Cloud-rendered Avatar Studio and Convai Sim[1], [2], [3]

Deployment: Convai-hosted service, Enterprise private or custom deployment[1], [2], [3]

Important considerations
  • Plan quotas limit monthly interactions, active end users, cloud-rendered minutes, and simultaneous character sessions.[2], [6]
  • Character creation APIs and domain embedding are unavailable on the lower tiers and require Professional or above on the checked pages.[2], [4]
  • Convai's own FAQ recommends guardrails and limiting external information to reduce hallucinations and keep characters aligned with their backstory and knowledge.[6]
