## What it is
LangChain is a framework for building agents and LLM-powered applications. It helps you chain together interoperable components and third-party integrations to simplify AI application development — all while future-proofing decisions as the underlying technology evolves.

## When to use it
Reach for langchain when you want an LLM to plan, call tools, browse, or coordinate with other agents instead of answering a single prompt — it's written in Python and fits stacks tagged ai-agents, ai, anthropic, chatgpt.

## Maintenance
