Understanding AI, Step by Step — Free Courses for Everyone
A free, no-code, no-jargon visual course series that takes you from “what even is AI?” all the way to creating with AI, working with data, and thriving in an AI future. Eleven short courses, 25 slides each — perfect for school & college students, teachers, and curious beginners. Bookmark this page: I keep adding new topics here.
Each course works offline — just open it in any browser, use ← / → to move, F for fullscreen. Suggested time: ~60–90 minutes each.
How Intelligence Works — Brain to AI
The story behind the story. What intelligence really is, how your brain works (neurons, synapses, learning), and how humans copied the neuron to invent AI — plus a brief history of who invented it and when. The perfect warm-up for Course 1.
Open the course →AI · LLMs · Generative AI — Explained
The foundation. What AI is, what an LLM is, what Generative AI is, and how they join together to power the AI everyone uses today. No coding, no maths, no jargon.
Open the course →Prompting — Talking to AI
How to talk to AI so it actually helps: better questions in, far better answers out. Learn the checklist — Task · Context · Format · Tone · Example · Iterate · Verify.
Open the course →Under the Hood — Tokens, Context & Embeddings
Opens the “black box”: why does AI forget? why does it cost money? how does it seem to understand what I mean? Meet tokens, the context window, embeddings and grounding (RAG).
Open the course →Making AI Do Things — APIs, Tools & Structured Output
Where AI stops just talking and starts doing — checking the weather, doing maths, sending a message — using APIs, JSON and tools. Ends with a gentle taste of code.
Open the course →AI Agents · RAG · Agentic AI
From intuition to a working understanding of AI Agents (the doer), RAG (the fact-checker), and Agentic AI (the team of agents that plan and collaborate toward a goal).
Open the course →Using AI Responsibly — Evaluation, Safety & Guardrails
Being a smart, safe and fair user of AI: judging whether AI is right, staying safe (privacy, security, guardrails), and doing the right thing. Five habits: CHECK · PROTECT · QUESTION · CREDIT · DECIDE.
Open the course →AI in Everyday Life — Study, Create & Organize
Turn AI into an everyday superpower: a patient tutor for studying, a partner for writing and ideas, and a planner for daily life — used well and safely. Five habits: ASK WELL · ITERATE · VERIFY · STAY PRIVATE · STAY IN CHARGE.
Open the course →Creating with AI — Images, Voice, Video & Music
Go beyond text and make things: generate and edit images, produce voices and music, and create video — with the ethics that matter (consent, deepfakes, copyright, labelling). CREATE BOLDLY · CREDIT HONESTLY · LABEL AI WORK · GET CONSENT.
Open the course →AI & Data — How AI Learns, Explores & Respects Data
Data is the fuel behind every AI. See how AI learns from data, how you can explore data with AI (no formulas!), and the data-literacy habits everyone needs — privacy, bias, and reading charts honestly. SOURCE IT · SEE IT · QUESTION IT · CHECK FOR BIAS · PROTECT IT.
Open the course →The Future of AI & You — Careers, Skills & What Comes Next
The grand finale. Where AI is heading (agents, multimodal, AGI, safety), what it means for jobs and skills, and how you can thrive and be a force for good. Your toolkit for life: PROMPT · VERIFY · PROTECT · CREATE · DECIDE.
