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.
CustomCharisma.ai's PRO plan is pay-as-you-go and built for developers using Charisma's SDKs on smaller bespoke projects, priced at $5 per 50,000 credits, roughly equivalent to 200 minutes of experience runtime. It includes access to the SDKs, story collaboration and script flow tools, speech-to-text, the AI voice library, custom voice integration, additional languages, and generative AI dialogue features.
There is no separate mid-tier plan; organizations with higher usage needs or that require a fully built experience move to the Enterprise tier. Enterprise pricing combines a one-off development fee tailored to the project (covering front-end build for web, mobile, app, game, or VR, visual design, script-writing, and technical support) with a fixed monthly platform fee based on estimated usage.
Enterprise plans include everything in PRO plus additional premium AI voices, admin-only platform tools, a user management system, a dedicated account manager, and access to Training & Development templates. Exact Enterprise pricing requires contacting Charisma's sales team directly.

Summary
Build lifelike 3D AI characters with real-time vision, voice, and memory for games and virtual worlds
Immersive conversational AI for training simulations and brand experiences
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
Charisma.ai Pros & Cons

Cons
- Full production features like front-end development and account management are only available on custom Enterprise pricing
