Inworld

Inworld AI is a revolutionary character engine that transforms static scripts into lifelike digital beings in minutes. Its sub-200 ms latency, 11-language TTS, drag-and-drop personality studio, and persistent memory slash development cycles for games, marketing, and education while delivering cinematic realism.

Text-to-Speech That Rivals Human Voice Actors

Inworld TTS supports 11 languages and offers instant voice cloning with as little as three seconds of audio. The pricing model charges per 1,000 characters, undercutting major cloud providers by up to 60 %. Latency is consistently below 150 ms, making it viable for real-time multiplayer games.

Character Studio: No-Code Personality Design

Drag-and-drop sliders control 24 personality dimensions—openness, neuroticism, risk tolerance, humor style, and more. Context nodes let writers inject lore, brand guidelines, or regulatory constraints without touching code. The studio auto-generates a REST endpoint and WebSocket URL for immediate integration into Unity, Unreal, or React apps.

Context-Aware Memory

Characters remember user names, previous choices, and evolving story arcs. The memory layer compresses old interactions into high-level summaries, preventing ballooning token counts while preserving continuity. Developers can export memory snapshots for analytics or compliance audits.
