So I can actually start building with Claude Code.
Zero to Claude Code is a free interactive course for people who've never written code. It starts with “what is a folder?” — 150 lessons later, you've shipped something real with Claude Code that you can show off.
Not a prompt-tricks collection — a complete on-ramp
There's plenty of “how to use Claude Code” content out there, but most of it assumes you already know how to code, navigate a terminal, and read a git diff. This course doesn't.
It starts with how computers actually work: files, folders, paths, terminal commands, Git/GitHub, JavaScript and Node, APIs, HTTP, databases — every word you'll want to recognize when you're talking to Claude Code. Only then does it get into Claude Code itself, Skills, MCP, context design, advanced workflows, and the capstone.
The capstone is a real multiplayer game you can play online with friends — not a hello world.
For people who want to build with AI but don't know where to start
- Non-engineers: marketers, PMs, designers who want to ship their own small tools or MVPs
- Founders and indie hackers: not ready to hire engineers yet — validate the product with AI first
- ChatGPT / Claude.ai users who want to go deeper — from “chatting with AI” to “building with AI”
- Students and self-learners: curious what engineers actually do, and where AI fits in the workflow
Not for: senior engineers with 5+ years of experience (this will be too basic); or anyone looking for a “become a full-stack engineer in a week” shortcut (this is the long, systematic path).
I've spent 13 years lowering the bar for learning
I'm Richard Zenn — founder of VoiceTube; CEO for 8 years, now Chief Innovation Officer. Engineering background (PChome → Groupon → founded VoiceTube), and I've spent 13 years making English learning fun and free.
VoiceTube had a free tier from day one because I believe one thing: learning resources locked behind paywalls get missed by the people who need them most. claude2code.com runs on the same principle — no premium tier, no “unlock the full content” button, no subscription.
From the first commit to launch, every line of code on this site was paired with Claude Code — on weekend nights while running VoiceTube during the day. So this site is itself a working example of what a non-full-time engineer can ship with AI. I give direction, make decisions, review diffs; Claude writes the implementation, explains choices, and fixes bugs.
Systematic, interactive, no videos
- Systematic: not “10 Claude Code tips” — it's 14 chapters from computer basics all the way to the capstone. 5–16 lessons per chapter, 5–10 minutes each.
- Interactive: all 150 lessons are hands-on — virtual terminal, quizzes, fill-in-the-blank, drag-and-match, AI prompt templates, paired coding steps. No videos to passively watch.
- You ship something: chapter 14 is the capstone — a real multiplayer game you can play online. You finish with something you can show friends or put on a resume.
- Originally written for 繁中 readers: every lesson was first authored and human-edited in Traditional Chinese (Taiwan terminology, punctuation, conventions). The English version covers everything — UI chrome plus full lesson content.
