View on n8n.io →Enrich records with AI-generated summaries, classifications, or embeddings.
AI enrichment workflows use language models, embedding pipelines, and classification APIs to add structured intelligence to raw records. Templates in this category take unstructured input — a support ticket, a product review, a contact record, a scraped web page — and return summaries, sentiment scores, category labels, embeddings for vector search, or generated fields that would otherwise require manual review. Simple workflows call a single AI model and write the output back to one field; intermediate builds chain multiple models or add conditional branching based on classification output; advanced workflows orchestrate multi-step enrichment pipelines with fallback logic, cost controls, and output validation. AI adoption is by definition 100% in this category. Demand Score reflects builder engagement — high-view templates signal enrichment patterns that are widely applicable across industries. Because AI enrichment is one of the fastest-moving areas in automation, Demand Score velocity is particularly meaningful. Paid members access ranked demand intelligence showing which enrichment patterns are gaining adoption fastest.
