# Overview

The Aurelio SDK provides a streamlined interface to the Aurelio Platform's document processing capabilities. It enables developers to extract, chunk, and embed textual content from various sources with minimal effort.

## What is Aurelio SDK?

Aurelio SDK is a Python library that abstracts the complexity of document processing pipelines. It offers both synchronous and asynchronous clients to interact with the Aurelio Platform.

## Core Capabilities

### Document Extraction

Extract text from multiple sources including:

* PDF documents (local files or URLs)
* Video files with automatic transcription
* Web-based content

### Intelligent Chunking

Break down documents into meaningful segments using:

* Semantic chunking that respects content boundaries
* Configurable parameters for chunk size and overlap
* Window-based processing for context preservation

### Embeddings Generation

Transform text into vector representations using:

* Multiple embedding models including BM25
* Batch processing for efficiency
* Consistent vector formats for downstream applications

## When to Use Aurelio SDK

Aurelio SDK is particularly useful when:

* Building document processing pipelines that require extraction and structuring of content
* Implementing semantic search capabilities across large document collections
* Preparing text data for large language model applications
* Creating NLP workflows that need consistent text chunking and embedding

## Architecture

The SDK follows a client-based architecture:

%%{init: {'theme':'neutral', 'themeVariables': {'darkMode': true, 'primaryColor': '#4182c3', 'primaryTextColor': '#fff', 'primaryBorderColor': '#7a7a7a', 'lineColor': '#7a7a7a', 'secondaryColor': '#f5f5f5', 'tertiaryColor': '#333'}}}%%

```

This structure allows for clean separation of concerns, with the SDK handling authentication, request formatting, and response parsing, letting you focus on your application logic.
