# Introduction
In today’s data-driven world, the ability to efficiently classify and extract information from documents is crucial for businesses. Traditional methods, primarily Optical Character Recognition (OCR), often fall short in terms of accuracy and flexibility. Enter AI and vision models, which revolutionize document processing by leveraging machine learning techniques.
In this guide, we will cover:
– The mechanics of document classification and extraction using AI.
– Advantages of vision models over traditional OCR.
– How to get started with n8n to implement these AI capabilities.
## Understanding Document Classification and Extraction
### What is Document Classification?
Document classification refers to the automatic categorization of documents based on their content. This can include sorting documents into predefined categories such as invoices, contracts, reports, and more.
### What is Document Extraction?
Document extraction involves pulling specific information from documents, such as text, figures, and tables, to facilitate data processing and analysis.
