Made Crystal Clear

A practical, visual guide to AI concepts for leaders and curious minds, no code required

Every meeting now has an AI conversation, and most of the room is nodding along to words they could not define: agent, harness, RAG, context window, fine-tuning, evals. This guide fixes that in an afternoon. It explains how AI actually works and what the terminology really means, in plain language with a diagram for every concept, so managers, support and ops leaders, and curious professionals can ask sharp questions, judge vendor claims, and make confident decisions. No code, no math, no hype.
