LangChain is ideal when your AI app needs:
- Complex logic flows
- Access to tools or external data
- Retrieval from large corporations
- Conversational memory
- Autonomous reasoning (agents)
As large language models (LLMs) become more powerful, a key challenge emerges: How do we move from a smart chatbot to a fully functional AI application?
That’s where LangChain comes in.
What is LangChain?
LangChain is an open-source framework designed to help developers build applications that use LLMs more effectively by connecting them with:
Data (PDFs, SQL, APIs, etc.), tools (web search, code execution), memory, reasoning flows (via Chains or Agents).
