I designed and implemented an end-to-end AI-powered knowledge base using n8n to automate data ingestion, processing, and intelligent retrieval.All data is initially created and managed in NocoDB, where it serves as a structured source of truth. n8n workflows automatically sync new and updated records, normalize the data, and prepare it for AI processing. Content is then enriched and converted into semantic embeddings using OpenAI, and stored in Supabase (PostgreSQL + Vector Store) for scalable, high-performance semantic search.
