What You'll Learn — 8 Stages

  • 01
    What Is an LLM?
    Neural networks, parameters, and why a billion numbers can "understand" language.
  • 02
    Feeding the Brain — Training Data
    Where LLMs get their knowledge and why data quality determines everything.
  • 03
    Tokens — The Atoms of Text
    How models break language into pieces and why "tokenization" matters more than you think.
  • 04
    Learning to Predict — How Training Works
    Next-token prediction, loss functions, and backpropagation — explained visually.
  • 05
    The Transformer — Attention Is All You Need
    The architecture behind every modern LLM, broken down step by step.
  • 06
    From Autocomplete to Assistant
    SFT, RLHF, and how a text predictor becomes a helpful AI assistant.
  • 07
    Superpowers & Quirks
    Hallucinations, context windows, prompt engineering, and the real limits of LLMs.
  • 08
    The Future — What's Next?
    Agents, multimodal models, reasoning, and where the field is heading.

This Is Not a Lecture — It's Interactive

Every stage includes a hands-on exercise. You learn by doing, not just reading.

Neural Network Playground Click neurons and watch signals fire through a live network.
Data Sorting Game Drag-and-drop training examples to see how data quality affects output.
Live Tokenizer Type any sentence and watch it split into tokens in real time.
Training Visualizer Watch a model learn word by word — see the loss curve drop live.
Attention Heatmap See which words the transformer "pays attention to" in a sentence.
Pipeline Builder Assemble pre-training, SFT, and RLHF stages like building blocks.
Hallucination Detector Spot the made-up facts in AI-generated text — a real-world skill.
LLM OS Simulator Wire tools and APIs together to build an AI agent in a sandbox.

Who Is This For?

  • Daily AI users — You use ChatGPT, Claude, or Copilot every day but have no idea what's happening under the hood. This course gives you that understanding.
  • Software engineers — You can code but LLMs feel like a black box. This fills the gap between "I can call an API" and "I understand what the model is actually doing."
  • PMs, founders & decision-makers — You need to evaluate AI products and make strategic bets. Understanding the fundamentals helps you ask better questions.
  • Students & career switchers — You're exploring AI/ML and want a clear, structured starting point before diving into textbooks and papers.
No math or programming background required. If you can read this sentence, you can take this course.

Frequently Asked Questions

How long does the course take?

About 2 hours if you go through everything, including exercises and quizzes. You can stop and resume anytime — your progress is saved in your browser.

Do I need a technical background?

No. The course is designed for curious people, not specialists. No math, no code, no prerequisites. Everything is explained visually and interactively.

Is this a subscription?

No. You pay $1 once and get access forever. There are no recurring charges, no upsells, no "premium tier."

What happens after I pay?

The course link is emailed to you immediately after payment. Check your inbox (and spam folder, just in case) — you'll receive a direct link to start learning right away.

Why is it only $1?

Because understanding AI shouldn't be gated behind a $200 paywall. The $1 price keeps it accessible to everyone while signaling that this is real, curated content — not a throwaway freebie.

Does it work on mobile?

Yes. The entire course — including all interactive exercises — is fully responsive and works on phones and tablets.


You're one dollar away from actually understanding AI.
