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.
FreemiumInworld AI uses a credit-based subscription model with a free On-Demand tier for evaluation and prototyping, including up to 70 minutes of TTS or 400 minutes of STT at no cost, with 100 custom voices and full Realtime API access under a commercial license.
Paid plans start with Creator at $25/month (up to 33% off base rates), Builder at $100/month (up to 40% off, workspace sharing), Developer at $300/month (up to 47% off, priority email support), and Growth at $1,500/month (up to 53% off, 30,000 custom voices, HIPAA and BAA add-ons). Realtime TTS-2 pricing ranges from $25 per million characters on-demand down to $12.50 on the Growth plan, with Realtime TTS-2 Flash starting at $15 and falling to $7.
Enterprise pricing is fully custom, with Realtime TTS-2 rates as low as $5 per million characters, price-match guarantees, SLAs, EU and India data residency, and a dedicated account manager. Unused subscription credits roll over for up to 3 months, and LLM usage through the Realtime Router is billed at provider cost with no markup.

Summary
Build lifelike 3D AI characters with real-time vision, voice, and memory for games and virtual worlds
Realtime TTS, STT, and LLM routing infrastructure for consumer-scale voice AI
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
Inworld AI Pros & Cons
Pros
- Realtime TTS consistently ranks #1 on the Artificial Analysis Speech Arena in blind user tests
- Significantly cheaper than comparable providers like ElevenLabs and Deepgram at scale
- Single API and WebSocket connection covers STT, LLM routing, and TTS together
- Provider-agnostic LLM routing avoids vendor lock-in and lets teams swap models anytime
- Enterprise-grade compliance built in, including SOC 2 Type II, HIPAA, and GDPR
Cons
- Full pricing benefits require higher-tier paid plans, which may be costly for very small projects
- Advanced compliance features like HIPAA, BAA, and zero data retention are gated behind add-ons or Enterprise
- Professional voice cloning is only available from the Developer plan and above
- Some capabilities like WebRTC and SIP transport are still in early access rather than general availability
