# Introduction

> What VoicEra is, how it works, and what people build with it.

Three short pages for deciding whether VoicEra fits your problem — before you install anything.

| Page                               | Read it for                                                                         |
| ---------------------------------- | ----------------------------------------------------------------------------------- |
| [What is VoicEra](what-is-voicera) | The plain-language overview, and what VoicEra deliberately is not.                  |
| [How it works](how-it-works)       | The path of a single call, from ring to hangup.                                     |
| [Use cases](use-cases)             | Inbound helplines, outbound campaigns, IVR replacement, data-sensitive deployments. |

VoicEra turns a phone call into a conversation with a language model. Speech arrives from a telephony carrier or a browser, gets transcribed, goes to an LLM with your prompt and optionally your documents, and the reply is spoken back — fast enough to feel like a conversation. You self-host all of it, and you choose every provider in that chain.
