LangChain
LangChain is a framework for building LLM-powered applications with agents, tools, and retrieval (rag) workflows.
Overview
LangChain is built for developers who want more than a chatbox. It enables structured AI workflows where an LLM can call tools, query knowledge sources, follow multi-step plans, and generate grounded responses. Whether you’re building an internal knowledge assistant, customer support automation, data-aware copilots, or agent-driven task execution, LangChain provides the components and patterns to connect models to your stack and keep outputs consistent and controllable.
Core Features & Capabilities
Ideal for developers and AI teams building production LLM applications such as knowledge assistants, customer support copilots, workflow automation agents, and RAG systems that need reliable connections to real data and tools.
- build agents that call tools and APIs safely
- rag pipelines that ground answers in your documents and data
- workflow orchestration for multi-step reasoning and actions
- integrations with llms, vector stores, databases, and apps
- logging and evaluation-ready patterns for production use
Trending Use Cases
Why Builders Choose LangChain
Start with a simple chain for your use case (summarise, classify, extract), then add retrieval by connecting your documents or database. Next, introduce tools (APIs, search, actions) and build an agent for multi-step tasks. Add logging and evaluation early, and iterate with real user queries to tune prompts, retrieval settings, and tool behaviors.
“LangChain gives us the building blocks to go from LLM prototype to real agent workflows connected to data and tools.”
Getting Started with LangChain
By combining agent orchestration, retrieval, and integrations into a repeatable framework, LangChain helps teams build AI applications that are more actionable, data-aware, and production-ready.

LangChain
LangChain is a framework and ecosystem for building LLM-powered applications with agents, retrieval, tool calling, and workflow orchestration—helping developers connect models to real systems and data.
LangChain helps developers build production-ready LLM apps by providing building blocks for prompting, tool use, agents, memory, and retrieval-augmented generation (RAG). It’s designed for assembling end-to-end AI systems that connect models to real data sources (documents, databases, APIs), orchestrate multi-step reasoning, and deliver reliable outputs in real workflows. With a strong ecosystem for integrations, evaluation, and deployment patterns, LangChain accelerates the path from prototype to scalable AI applications.
