Summary
Most organizations already have the ingredients for enterprise AI success. They have SharePoint. They have years of accumulated knowledge stored across documents, spreadsheets, policies, manuals, contracts, and project files. They may even have access to powerful AI models. Yet when employees ask questions, the answers are often incomplete, inaccurate, or missing entirely.The problem isn't the AI model.The problem is retrieval.In this episode of the M365 FM Podcast, we take a deep dive into building a fully private Retrieval-Augmented Generation (RAG) platform using SharePoint, Microsoft Graph, n8n, Mistral OCR, Azure OpenAI, PostgreSQL, Supabase, and Open WebUI. Rather than focusing on theory, this episode walks through the complete architecture required to transform a traditional SharePoint environment into a secure, enterprise-grade AI knowledge system capable of answering questions based on your organization's own content. WHAT RAG REALLY IS Retrieval-Augmented Generation is often described as giving AI access to your documents, but that explanation barely scratches the surface. The reality is that a RAG system introduces an entirely new layer between the user and the language model. This retrieval layer determines what information reaches the model and ultimately dictates the quality of every answer.We explore how vector embeddings work, why semantic search differs fundamentally from keyword search, and why organizations that focus solely on upgrading models often fail to improve answer quality. You'll learn why retrieval accuracy is the true foundation of successful enterprise AI. WHY SHAREPOINT SEARCH IS NO LONGER ENOUGH Traditional SharePoint search was designed for finding documents. Modern knowledge workers need answers.Throughout the episode, we examine why…
