What are n8n's core AI node components?

Four core: LLM Chat (multi-provider + local), Vector Store (Pinecone/Qdrant etc), Document Loader (PDF/Word auto-parse), AI Agent (autonomous tool calling and multi-step reasoning).

What advantages over Zapier and Make?

Fully open-source self-hostable (one-click Docker), unlimited free AI features, native AI Agent support, vector search, deep LangChain integration. Zapier/Make are closed-source with limited AI.

How does n8n integrate with LangChain?

Architecture-level deep integration: visualizes LangChain's Chain, Agent, Memory, Tool abstractions as drag-drop nodes, wraps 400+ integrations as LangChain Tools, no Python code needed.
