Visual Explainer Series

Four interactive series

Understand AI, and how far you want to take it.

Start with how it works. Go as deep as you want — the equations and the code, or a real local chatbot you build yourself. Every page is one interactive idea, built to operate yourself — not a wall of text.

For anyone who uses AI

AI Concepts

How AI actually works, from tokens to agents — no coding or math required. Read the beginner series in order, keep going with a denser Intermediate tier, then a tier on how AI makes pictures, sound, and video.

Agents at Work

How a real agent-driven software delivery pipeline works — role-scoped agents, fixed stages, human gates, and everything that keeps it safe to run unattended.

How AI Reads Software

How AI actually understands an enterprise codebase — what it can and can't see, how it finds the right file, and why a confident answer isn't always a correct one. No coding required.

AI Engineering: Deep Dive

The real math and real code behind the buzzwords — dot products, matrix multiplication, attention — worked by hand on one running example (a fictional support-doc assistant) across every page.

Build a Local Chatbot

Run a real model on your own machine and watch every mechanism actually happen — tokenizing, generating, a chat loop with memory, guardrails, a working UI. Every page ships a runnable script, setup included, zero assumed experience.
