Is the AI Lab really free?

Yes — all twenty-four modules and games are completely free. No credit card, no trial. Everything is simulated, so there is no usage cost, and we offer it as a hands-on introduction to modern AI.

Do I need to know how to code?

No. The AI Lab is designed for curious beginners. If you can click buttons and drag a slider, you can learn the core ideas behind modern AI here.

Will my progress be saved?

Yes — your XP, badges, streak, and completed items are saved in your browser. Come back anytime and pick up where you left off. No signup required.

What's the Agentic AI Masterclass?

It’s our hands-on course that takes you from a written spec to a deployed AI agent — building real retrieval, prompting, and tool-using systems with spec-driven development. The Lab teaches the concepts; the masterclass teaches you to build with them.

Will you spam me if I give my email?

No. You’ll get one confirmation email and occasional, relevant updates. No spam, no selling your address, and you can unsubscribe anytime.

The Sandwich Robot

Prompt Clarity

The #1 skill for getting good AI output. Write instructions so clear there’s no room for guessing — and watch a literal-minded robot show you exactly where vague prompts fail.

Active

What this means

AI tools like ChatGPT, Claude, and Gemini don’t think the way we do — they follow your words literally. If your instructions are vague, the AI guesses. If they’re precise, it delivers exactly what you wanted. "Prompt clarity" just means: write instructions that leave no room for guessing. Try it below.

The robot does exactly what you say. Nothing more.

Choose your prompt

Vague

"Make me a sandwich."

Detailed

"Two slices of brown bread, cheese, tomato, no mayo, cut diagonal."

Pick a prompt to see what the robot builds. Try both to unlock Module 2.

The Smart Assistant

RAG

How to stop AI from making things up. Pick which documents an AI can read before it answers — and watch its response change with every document you add or remove.

The Meaning Map

Embeddings

How AI "understands" meaning. Explore a map where words with similar meanings sit close together — the trick behind search, recommendations, and autocorrect.
