About

The developer platform for AI characters. Get a fully integrated platform for AI characters that goes beyond large language models (LLMs), and adds configurable safety, knowledge, memory, narrative controls, multimodality, and more. Craft characters with distinct personalities and contextual awareness that stay in-world or on brand. Seamlessly integrate into real-time applications, with optimization for scale and performance built-in. Optimized for real-time experiences, Inworld offers low-latency interactions that scale with your application. Orchestrating across LLMs allows us to deliver high-quality interactions with faster inference and lower costs. Every interaction has a context and models need to be aware of yours. Add custom knowledge, content and safety guardrails, and narrative controls to keep your AI in character, in-world, or on brand. Put personality at the center of your AI. Our multimodal AI mimics the full range of human expression.

About

Inworld TTS is a state-of-the-art text-to-speech platform designed to deliver ultra-realistic, context-aware speech synthesis and precise voice-cloning capabilities at a radically accessible price. The flagship model, TTS-1, is optimized for real-time applications and supports low-latency streaming (first audio chunk in ≈200 ms) as well as multiple languages (including English, Spanish, French, Korean, Chinese, and more). Developers can use instant zero-shot voice cloning (5-15 seconds of audio) or professional fine-tuned cloning, add voice-tags for emotion, style, and non-verbal sounds, and switch languages while preserving voice identity. The larger TTS-1-Max model (in preview) offers even more expressive speech and multilingual strength. The platform supports both API and portal access, streaming or batch mode, and is designed for everything from interactive voice agents and gaming characters to branded audio experiences.
