LangChain
Framework for building applications with LLMs and agents, including web and tool use.
Overview
LangChain is a framework for developing applications powered by language models. It provides abstractions for chains, agents, tools, and retrieval, including web browsing and document parsing.
Relevance to GEO
Agents built with LangChain often consume web content. Sites that follow GEO practices (structured data, clear semantics, llms.txt) are easier for LangChain-based agents to parse and use reliably.
