This beginner-friendly course introduces the key components and workflows of LangChain, providing practical explanations for developers and AI enthusiasts who want to build intelligent LLM-powered applications.

The course begins with a clear overview of LangChain and its purpose in AI pipelines. Learners explore document loaders, text splitters, and embeddings to efficiently process and represent textual data. The use of vector stores is explained in detail, showing how to store and retrieve information effectively for retrieval-augmented generation (RAG) tasks.

Next, the course covers retrievers, highlighting their role in querying vector databases and fetching relevant documents for LLM responses. Prompt creation and management are discussed, with examples demonstrating how to craft effective prompts for different use cases. The course also explains how to choose and use models within LangChain, ensuring correct execution and output.

Finally, output parsers are introduced, showing how to format and structure responses from the LLM for downstream applications. By the end of the course, learners will understand all core LangChain components, enabling them to build functional, scalable, and intelligent AI pipelines with confidence.
