Explain AI
AI can sound complicated, but it does not have to be. This is the place where jargon becomes plain English, and big ideas become things you actually get.
No math degree required. No prior experience needed. Just curiosity.
Who is this for?
The Complete Beginner
You have heard of ChatGPT but have no idea what is actually going on under the hood.
Start with ChatGPT and AI Basics and work your way up, one small concept at a time.
The Curious Builder
You are using AI tools and want to use them better. You will find lessons on prompting,
how models think, and practical guides for getting real results.
The Parent or Teacher
You want to explain AI to someone else, like a student, a kid, or a colleague, without
sounding like a textbook. These plain-English lessons are made for exactly that.
The Professional
AI is showing up in your industry and you need to get up to speed fast. Our lessons
cut through the hype and focus on what actually matters.
How it works
01
Pick a lesson. Each lesson covers one idea, kept short so you finish
what you start. No giant essays.
02
Read the analogy first. Every concept starts with a plain everyday
comparison before the technical details. The goal is that "oh, I get it" moment.
03
Check your understanding. Each lesson ends with a recap so you know
exactly what you learned.
04
Keep going. Lessons link to the next concept. You can also browse all
lessons any time.
Recommended path
12-LESSON BEGINNER PATH
The beginner path runs in three phases. Phase 1 covers orientation: what ChatGPT is, why it took off, and what GPT and LLMs mean. Phase 2 covers the mechanics: how chatbots generate answers, tokens, context windows, and the Transformer architecture. Phase 3 covers practical understanding: attention, prompting, hallucinations, and retrieval.
Phase 1 Orientation ChatGPT, why it became popular, GPT, and LLMs
Phase 2 How It Works Answer generation, tokens, context windows, transformers
Phase 3 Using It Well Attention, prompting, hallucinations, RAG
