Langchain
LangChain’s suite of products supports AI development
LangChain is an open-source framework to build applications using language models (LLMs), simplifying integration with external data, APIs, and custom logic. It offers chains, agents, memory, retrieval (RAG), and support for databases, vector stores, and various tools — making it easy to turn LLMs into practical solutions like chatbots, document analysis systems, search engines, and automation workflows. LangChain accelerates development, ensures flexibility, and avoids vendor lock-in.
