# Introduction

> Platform overview and live demo

Agentic OS is a platform for building, deploying, and managing AI voice agents.
We handle the complex infrastructure — telephony, speech-to-text, LLM orchestration,
and text-to-speech — so you can focus on the conversation itself.

## How it works

Every Agentic OS agent combines three core building blocks:

1. **Transcriber** — converts caller speech to text in real time
2. **LLM** — generates the agent's response based on your prompt and tools
3. **Synthesizer** — converts the response back to natural-sounding speech

You choose the providers for each: OpenAI, Anthropic, or Google for the LLM;
Deepgram or Google for transcription; ElevenLabs or Azure for voice.
