Convai
Freemium
Convai is a conversational AI platform for building interactive characters in games, XR, and virtual worlds, with browser creation, developer integrations, and tiered plans.
What is Convai?
Convai is a conversational AI platform for virtual worlds, games, XR, metaverse experiences, and related interactive environments. It is designed to help teams create 3D AI characters that can speak with users, perceive context, and take actions inside a scene.
The product combines creator-friendly tools with developer-facing infrastructure. The homepage describes no-code creation from the browser or a local system, while the developer material highlights support for Unreal Engine, Unity, 3JS, open APIs, tutorials, and documentation. The pricing page adds tiered plans for solo builders, teams, and larger production use, with an Enterprise path for data ownership, security, compliance, and service-level agreements.
What can Convai do?
Real-Time Perception
Use multimodal perception so characters can see and hear their surroundings before responding, which helps make replies more context-aware.
No-Code Character Creation
Create characters through no-code tools in the browser or on a local system, which supports both creator-led and developer-led workflows.
Developer Integrations
Connect with popular game engines and developer tooling through plugins, open APIs, tutorials, documentation, and support.
Knowledge and Scene Awareness
Work with knowledge banks and scene-aware actions described in the company blog to give characters topic knowledge and let them respond to scene metadata.
Usage-Based Plan Tiers
Choose from plan tiers that differentiate by quotas such as interactions, active end users, concurrency, and branding options.
Use Cases
“Interactive Game Characters”
Build NPCs or virtual characters that can converse with players or visitors using natural language, voice, and context from the scene.
“Immersive Virtual Worlds”
Create XR or metaverse experiences where characters respond to what is happening around them and act inside the environment.
“Rapid Character Prototyping”
Use the browser-based or local creation tools to prototype a character quickly before moving into a more integrated development workflow.
“Team and Enterprise Deployment”
Use the platform's higher tiers and enterprise path when a project needs more scale, more users, or controls around data ownership and compliance.
Frequently Asked Questions
Who is Convai for?
Convai is designed to help creators and developers build conversational characters for virtual worlds. The source materials describe browser-based no-code tools, local development workflows, and developer-facing APIs and plugins for engines such as Unreal Engine, Unity, and 3JS.
How do people build with Convai?
The source describes Convai as supporting both no-code creation and developer workflows. Creators can work from the browser or a local system, while developers can use integrations, open APIs, tutorials, documentation, and support to build characters into their projects.
What pricing options does Convai show?
The pricing page shows Free, Indie Dev, Professional, Scale, and Business plans, plus an Enterprise path focused on data ownership, security, compliance, and SLAs. The page also says paid upgrades are managed through the Billing page and that a seamless payment system is coming soon.
How are interactions counted?
The pricing page defines an interaction as a user input followed by an AI character response, whether the exchange is in text or voice. It also notes that interaction quotas reset each billing cycle and do not roll over.
What does character concurrency mean?
The pricing FAQ says character concurrency is the number of users who can interact with a character at the same time, and that the limit applies to the API key being deployed rather than each NPC individually.
