# Introduction

> What's San Francisco Voice Company

**We make voice AI better.**

Our first feature is a search engine for media.

You do not need to build your own transcript store, embedding pipeline, or media search layer first.

<Warning>
  These docs cover version `0.1.1`. We are iterating quickly, so pin your SDK version and expect breaking changes between versions until the API settles.
</Warning>

Search is where we start. Next up is benchmarking and toolings for voice AI systems.

## What you can build with our media SDKs.

* Search all audio by topic, objection, or feature request as humanly possible **"Where does customers got impatient?"**, or \*\*When did security guard left their work station?".
* Find calls where your AI interrupted the caller, spoke too slowly, or repeated itself.
* Find specifc content within a video even when nobody is talking.
* Build compliance review, QA workflows, or knowledge bases on top of your audio or video archive.

## Lifecycle

<Steps>
  <Step title="Ingest">
    Send a URL, authenticate us to your bucket via S3 key, or file upload with your `asset_id` (more details about [asset\_id]() and [asset\_class](#)). The API returns a `task_id` immediately.
  </Step>

  <Step title="Index">
    Poll the task until it reaches `ready`. Indexing runs in the background.
  </Step>

  <Step title="Search">
    Query with natural language, scoped to an `asset_class` or explicit `asset_ids`. Results include `start_ms` and `end_ms`.
  </Step>
</Steps>

## Data and privacy

We index your media and keep the searchable representation: embeddings, transcripts, and metadata. Source files pass through the processing pipeline and are not retained after indexing completes.

**You keep ownership of your media. We store the indexed data needed for search.**

Regional processing:

* **US customers** — processed in the United States.
* **EU and UK customers** — processed in Europe.
