How much does zuzu.codes cost?

The starter track is free — read all lessons and practice for free. Full access to every track (current and future) is $14.99/month. Cancel anytime.

How long does each track take?

Each track is designed as a 30-day challenge — one lesson per day, about 15 minutes each. Go at your own pace, but the structure is built around daily consistency.

What's the lesson format?

Each lesson is a student-teacher dialogue with code examples, followed by a hands-on code challenge in an in-browser editor. You read, you understand, then you write real code.

Do I need prior coding experience?

Our beginner track starts from absolute zero — no prior experience needed. Advanced tracks build on earlier ones, and the platform tells you exactly where to start.

How is zuzu.codes different from freeCodeCamp or Codecademy?

zuzu.codes uses a structured 30-day track format with dialogue-based teaching, an in-browser code editor, and gamification (XP, streaks, progress tracking). The format builds genuine understanding through daily practice.

Week 1 gave you one agent. Week 2 gave you typed output. Week 3 gave you pipelines and batch. How does the architecture feel now?

It feels like plumbing. I pick which agents to run, in what order, on what inputs — and the outputs are just Python values I can do anything with.

That's the systems moment. You're not using AI — you're composing AI-powered functions the same way you'd compose any Python functions. Which pattern from this week will you use first?

Batch classify. Forty messages, one function call, urgency labels on all of them. I can finally triage my Monday inbox in under a minute.

And next week you'll add web search and tools — so the agent can look something up before it answers. Let's confirm what you built this week.
