Meet Claude Code
Your AI teammate that lives where the work happens.
By the end of this lesson
You'll know exactly what Claude Code is and what it feels like to use.
Claude Code is Claude, given hands. Instead of chatting in a browser tab, it works inside your project — reading your files, writing new ones, running your app, and fixing what breaks.
you ▸ build me a habit tracker app with a dark theme and save data on my device claude ▸ creating project… ✓ claude ▸ writing the interface… ✓ claude ▸ adding local saving… ✓ claude ▸ starting it up to test… ✓ it works claude ▸ Done. Open http://localhost:3000 to see your habit tracker.
One honest note: real sessions are messier than this tidy transcript — walls of technical text scrolling by as it works. That scroll IS the work happening. You don't read it; you wait for the summary at the end. (And that http://localhost link in the example? It just means 'a page running on your own computer' — Module 4 shows you exactly how to open one.)
Vibe-coding. You bring the vibe — what you want, your taste, your judgment — and the AI brings the code. That word people throw around on social media? This course is exactly that: your onboarding into vibe-coding. By the end, it's just how you work.
The first time you watch an agent build something you asked for in plain English — then open it and it's real — something permanently changes. Skeptical? Good. Don't believe us — in two short modules you'll watch it happen on your own machine, and you can judge it there. (All you'll need: an ordinary Windows or Mac computer — a laptop is fine; a phone or tablet alone can't run Claude Code.)
