Pricing
FreemiumConvai's Creator module offers a Free tier ($0/month) for prototyping with a limited daily interaction quota, followed by paid tiers: Indie Dev at roughly $29/month, Professional at roughly $99/month, Scale at roughly $499/month, and Business at roughly $1,199/month, each increasing interaction quotas, character concurrency, and knowledge bank size. Beyond the Creator module, Convai offers an Enterprise module with fully custom pricing for large-scale or specialized deployments, along with Partner plans that operate on a revenue-sharing model with minimal upfront cost. Convai states its per-interaction pricing is designed to undercut the combined market rate of separately licensing speech-to-text, LLM, and text-to-speech services.
FreemiumUnity Personal Edition users can start a 14-day free trial that grants 1,000 AI credits one-time; after the trial, the in-editor assistant converts to a $10/month subscription for 1,000 credits per month, with additional credit bundles purchasable separately if needed. Unity Pro, Enterprise, and Industry subscribers automatically receive assistant access and credits included in their existing paid seats at no extra cost, simply by installing the assistant package and assigning seats in the organization dashboard. The AI Gateway does not consume Unity credits when connecting a third-party AI subscription, and the MCP Server is entirely free with no concurrency limits and requires no AI tools subscription at all, on any tier.

Summary
Build lifelike 3D AI characters with real-time vision, voice, and memory for games and virtual worlds
Unity's in-editor agentic assistant, AI gateway, and MCP server for game development (successor to Unity Muse)
Convai Pros & Cons
Pros
- Genuinely differentiated focus on embodied, spatially-aware 3D characters rather than flat chatbot interfaces
- Free developer tier makes it easy to prototype before committing to a paid plan
- Strong multimodal capabilities: real-time vision, 65+ languages, 500+ voices, and high-quality lip sync in one platform
- Deep, mature integrations with the game engines developers already use (Unity, Unreal Engine, PlayCanvas)
- Avatar- and platform-agnostic, letting the same character deploy across web, mobile, VR, AR, and physical installations
- Built by an experienced engineering team with enterprise-grade security and on-prem deployment options available
Cons
- Full featured plans jump quickly in price, from Free to $29/month to $99/month as usage and concurrency needs grow
- Building genuinely lifelike embodied characters still requires real integration work in Unity, Unreal Engine, or another supported engine
- Best results depend on pairing with a compatible avatar and animation system rather than working entirely out of the box
- Voice bot / IVR customization and non-visual conversational use cases are a smaller focus than its core 3D character strength
- Enterprise-level features like on-prem deployment and dedicated support require contacting sales rather than self-serve setup
Unity AI Tools Pros & Cons
Pros
- In-editor assistant is trained specifically on Unity workflows, not a general-purpose model bolted on afterward
- Project-aware context lets the assistant inspect and act on actual scene objects and components
- MCP Server and AI Gateway are both free with no concurrency limits, regardless of subscription tier
- Flexibility to bring your own third-party AI model/subscription instead of relying solely on Unity's system
- Full user control: undo support, AI-generated asset tagging, and granular permission settings
- Pro, Enterprise, and Industry subscribers get the assistant bundled into existing seats at no added cost
Cons
- Still in beta, so features, pricing, and stability are subject to change before general availability
- Requires Unity 6.0 or newer; the MCP server integration is not backwards compatible with older Unity versions
- Personal Edition users only get a one-time 1,000-credit trial before needing to pay $10/month, unlike Pro/Enterprise seats where it's bundled in
- Replaces the previous Unity Muse product, so any workflows, prompts, or assets built around Muse's first-party models will need to be rebuilt
- As a third-party-model-based system, output quality and behavior depend partly on which underlying AI model a developer chooses via the AI Gateway
