## What is RunAnywhere?

**RunAnywhere** is a production-grade, on-device AI platform that enables developers to run AI models directly on mobile devices and in the browser. Our SDKs provide a unified API for running AI inference locally — ensuring minimal latency, maximum privacy, and offline capability.

<Info>
  All AI inference runs **100% on-device**. Once models are downloaded, no network connection is
  required for inference.

## Core AI Capabilities

Every RunAnywhere SDK provides access to these powerful AI features:

  <Card title="LLM (Large Language Model)" icon="brain" href="/swift/llm/chat">
    On-device text generation with streaming support, structured outputs, and system prompts
  </Card>

  <Card title="STT (Speech-to-Text)" icon="microphone" href="/swift/stt/transcribe">
    Real-time audio transcription with multiple backends and multi-language support
  </Card>

  <Card title="TTS (Text-to-Speech)" icon="volume-high" href="/swift/tts/synthesize">
    Neural and system voice synthesis with customizable voice, pitch, rate, and volume
  </Card>

  <Card title="VAD (Voice Activity Detection)" icon="waveform" href="/swift/vad">
    Real-time speech detection for hands-free interactions
  </Card>
</CardGroup>

### Voice Agent Pipeline

Build complete voice-powered experiences with our integrated **Voice Agent** that orchestrates:

```mermaid theme={null}
graph LR
    A(VAD) --> B(STT)
    B --> C(LLM)
    C --> D(TTS)

    style A fill:#ff6900,color:#fff,stroke:#ff6900
    style B fill:#ff6900,color:#fff,stroke:#ff6900
    style C fill:#ff6900,color:#fff,stroke:#ff6900
    style D fill:#ff6900,color:#fff,stroke:#ff6900
```

This enables full voice conversation flows with streaming and batch processing modes.

## Why RunAnywhere?

<AccordionGroup>
  <Accordion title="Privacy by Design" icon="shield-check">
    Audio and text data never leaves the device unless you explicitly configure it. Only anonymous
    analytics are collected by default. Your users' data stays on their device.
  </Accordion>

  <Accordion title="Low Latency" icon="bolt">
    On-device inference eliminates network round-trips. Get AI responses in milliseconds, not
    seconds. Perfect for real-time voice interactions and responsive UIs.
  </Accordion>

  <Accordion title="Offline Capable" icon="wifi-slash">
    Once models are downloaded, your app works completely offline. No internet required for
    inference. Ideal for apps used in areas with poor connectivity.
  </Accordion>

  <Accordion title="Plugin Architecture" icon="puzzle-piece">
    Backend engines are optional modules—include only what you need. Keep your app binary size
    minimal by importing only the capabilities you use.
  </Accordion>
</AccordionGroup>
