LangChain is a powerful platform for developing and integrating natural language models, chat models, prompt templates, vector stores, and much more. Get started with our quickstart guide, and explore our extensive collection of modules and models. Use our async API to work with LLMs, or create your own custom LLM wrapper. Our integrations with AI21, Aleph Alpha, Azure, and other platforms make it easy to get started. Use our chat models for text embedding, prompt generation, and more. Our indexes can load documents from a wide range of sources, such as HTML, Markdown, PDF, and WhatsApp chats. Use our text splitters to split text by characters, words, or other criteria. Our vector stores, such as ElasticSearch and Redis, can be used to search for text in large datasets. Our retrievers can be used to retrieve information from these stores, based on keywords or other criteria. And our memory classes can store information about conversations, entities, and more, making it easy to build intelligent agents that can remember previous interactions. With LangChain, the possibilities are endless.
