# Welcome to SpatialReal Documentation

SpatialReal is the next-generation AI infrastructure for empathetic human-AI interactions. We build **real-time**, **high-fidelity**, and **cost-effective** digital avatar interactions through on-device rendering technology.

In the pipeline diagram: ASR = Automatic Speech Recognition, LLM = Large Language Model, TTS = Text-to-Speech, S2S = Speech-to-Speech (e.g. Gemini Live).

## Why SpatialReal?

Traditional digital avatar solutions force painful trade-offs between cost, visual quality, and real-time performance. SpatialReal solves this trilemma:

| Metric | Traditional Cloud Rendering | SpatialReal On-Device |
| - | - | - |
| **Bandwidth** | 1-2 MB/s (Video Stream) | 10-20 KB/s (Driver Data) |
| **Cost** | High GPU rental costs | Ultra-low edge compute |
| **Latency** | > 3s | \< 1.5s |
| **Compatibility** | High-speed network dependent | 99% of Android/iOS/Web devices |

## Use Cases

* **Online Education** - Immersive 1-on-1 tutoring with precise lip-sync for language learning and K12
* **Recruitment & Training** - 7x24h AI interviewers and roleplay training simulations
* **Customer Service** - Brand ambassadors with visual eye contact that builds emotional connection

## Quick Start

> **[Use LiveKit(recommended)](https://spatialwalk-6179c111.mintlify.site/overview/agent.md)**
>
> LiveKit is a realtime communication platform that allows you to create voice and video chat applications. Deploying your own LiveKit server is quick and easy.

> **[Use Avatarkit SDKs](https://spatialwalk-6179c111.mintlify.site/overview/speech-to-avatar.md)**
>
> For when you need full control of your tech stack (e.g., custom voice bots).

> **[Start building in 5 minutes](https://spatialwalk-6179c111.mintlify.site/overview/integration_overview.md)**
>
> Compare integration modes and start from runnable example projects.
