Spatius.ai
Spatius provides a real-time avatar layer that sits on top of existing voice AI stacks, converting audio into a compact motion stream that renders expressive avatars on-device. This approach eliminates cloud video streaming costs, with pricing starting at $0.36 per avatar hour. The platform supports Web, iOS, Android, kiosks, and embedded devices from a single SDK integration.

Problem
Voice AI interactions often lack a visual, human-like presence, making conversations feel impersonal and limiting engagement. Streaming high-quality video avatars to end users incurs prohibitive cloud bandwidth and compute costs, especially at scale, which prevents many companies from deploying expressive digital faces.
Solution
Spatius provides a real-time avatar layer that sits on top of any existing voice AI stack. The platform converts incoming audio into a compact expression and timing control stream, which is sent to an on-device renderer that draws the avatar locally on the user's device. This approach eliminates the need for continuous cloud video streaming, reducing cost while maintaining low latency and interruption-ready responsiveness. Businesses can deploy one avatar layer across Web, iOS, Android, kiosks, and embedded devices, and can create custom branded characters that fit their product's tone and setting. The SDK is designed for quick integration, with a developer playground and support for 100+ languages.
Target Audience
Primary customers are product teams and companies building voice AI applications—such as customer support, kiosk interfaces, and digital assistants—that need an expressive, human-like visual layer without the cost and latency of streaming video.
