Large Language Models (LLMs) like GPT can generate impressive responses, but building real-world AI applications requires more than just calling an API. Developers need structured workflows, memory handling, external tool integration, and document reasoning capabilities.

This is where **LangChain** becomes powerful.

LangChain is a framework designed to help developers build modular applications powered by language models by connecting prompts, memory, tools, agents, and external data sources into structured pipelines.
