Inworld AI
What is Inworld AI?
Inworld AI sells realtime voice APIs for text-to-speech, speech-to-text, speech-to-speech agents, and LLM routing, including avatar and NPC voice generation for games. Its Realtime TTS-2 models advertise 100 ms time-to-first-byte, voice cloning from 15 seconds of audio, bracketed voice steering tags, and support for 200+ languages on a single voice.
Compared with stitching together separate TTS, STT, and gateway vendors, Inworld bundles those layers into Realtime API sessions and a zero-markup Router across 220+ LLM models. The homepage publishes side-by-side rate cuts, such as $12.50 per 1M characters for Realtime TTS versus $100 at ElevenLabs on comparable growth plans, which targets teams shipping consumer voice apps at scale.
Game studios still use Inworld for NPC and companion voices, but the current product also targets education, health, social apps, and agentic workforce tools. Developers sign up on platform.inworld.ai, pick an On-Demand free tier or a paid monthly plan with credits, and integrate through REST or WebSocket APIs documented at docs.inworld.ai.
