Document Loaders Explained

Large Language Models (LLMs) are powerful, but their knowledge is limited to their training data. To make AI agents truly useful, they often need access to fresh, external information.

• Imagine an agent that needs to answer questions about today's news.
• Or one that summarizes a specific document from your company's internal drive.

This is where data loading comes in.

Document Loaders are LangChain's way of bringing external data into your agent's workflow. They act as bridges, converting raw data from various sources into a standardized format that LLMs can understand.

Think of them as specialized data connectors. They handle the messy details of reading files, fetching web pages, or querying databases, and then present the data cleanly to LangChain.
