LangChain helps developers build apps that connect language models to data sources and tools.
How It Works
LangChain handles the plumbing between AI models and everything else. It connects ChatGPT to your database, lets AI search the web, or chains multiple AI tasks together.
Think of it as middleware that makes AI models talk to other systems.
Why It Matters
Building AI apps without LangChain means writing lots of connection code from scratch. LangChain gives you pre-built pieces so you can focus on your app instead of integration details.
Most AI startups use LangChain or similar tools to build products faster.
