Best n8n rag pipelines.

Retrieval-augmented generation pipelines are the backbone of any LLM-over-your-data app. These are the cleanest ingestion + query patterns in the catalog: chunkers, embedders, retrievers, and the agent loops that stitch them together.

When to use these
Answering questions over your own corpus (docs, support tickets, code, PDFs). Reduces hallucination + lets the model cite sources.
Skip these if
Your corpus fits in the LLM's context window — just stuff the prompt.

What makes a workflow rank in this list

The QualityScore is calibrated against a hand-rated ground truth of 20 workflows (Spearman ρ = +0.941). Workflows score higher when they have: clean graph topology (no spaghetti), explicit error branches, sticky-note documentation, complete parameter coverage, and rich metadata (description, integrations, credentials). See the methodology page for the full axis breakdown.
