n8n-ai-nodes-official
Use when building or editing AI inside an n8n workflow: the AI Agent node, Text Classifier, Information Extractor, Sentiment Analysis, Summarization Chain, Basic LLM Chain, embeddings, vector stores, single one-shot LLM calls, or AI media generation (image / audio / video) via the native LangChain provider nodes. Also when a first-class n8n Agent can't do the job: trigger data mapped exactly into tool parameters, or memory shared across workflows. Triggers on any `@n8n/n8n-nodes-langchain.*` node, "AI Agent node", "LLM with tools", "tool calling", "fromAi", "system prompt", "memory window", "structured output", "outputParser", "RAG", "vector store", "embeddings", "classify with AI", "extract fields with LLM", "sentiment analysis", "summarize with LLM", "single LLM call", chat triggers with files, Slack / Discord / Teams / Telegram bot workflows, AI image / video / audio generation, or any multi-turn or one-shot LLM step in a workflow.
