You're about to understand AI.
Actually understand it.
Six short steps. No jargon without explanation. No course to finish. Just the things worth knowing — and what to do with them.
What AI actually is
Technically, artificial intelligence is a field of computer science focused on building systems that can perform tasks that normally require human thinking — recognizing patterns, understanding language, making decisions.
What AI means for you is more practical. The more you understand how it works, the more useful it becomes. It can think with you, for you, or because of you. You decide how much to invest — and the return scales with that investment.
Right now, the most useful form of AI for most people is a large language model (LLM) — a system trained on enormous amounts of text that can read, write, reason, and respond in plain language. You talk to it. It responds. The difference from a search engine: it understands context, remembers your conversation, and can reason through problems with you.

// watch the context window fill — click "send turn" to see what happens
The landscape
There are hundreds of AI tools. Most fall into two categories. You don't need both to start — but knowing the difference matters.
Open a browser. Type. Get a response. No setup, no installation. This is where everyone starts.
Describe what you want to build. The AI writes the code. More setup, but you can make real things.
The vocabulary
AI has its own language. You don't need to memorize this — but recognizing these terms means you'll stop feeling lost when you encounter them.

What it can do for you
Pick the one that sounds most useful right now. You'll get a starter prompt you can use today.
// your starter prompt — copy it, open Claude, fill in the brackets
// copied to clipboard
You're in.
That's the foundation. Everything else is just depth — and you add it at your own pace.
