Interactive AI Lessons

Free interactive lessons on how artificial intelligence works — machine learning, neural networks, deep learning, Transformers, and LLMs. No signup.

  1. 01What Is Artificial Intelligence? An Interactive IntroductionExplore what actually counts as AI — from ChatGPT to everyday tools — and what doesn’t. An interactive introduction with no signup.
  2. 02Why Rules Aren't Enough for AISee what happens when intelligence is written as rules: sticky notes pile up, edge cases multiply, and the system breaks. An interactive AI lesson.
  3. 03How Data Changed Artificial IntelligenceExplore why learning from data changed AI — and why systems that could learn decades ago only took off when data and compute arrived.
  4. 04How Does Machine Learning Work?How does a machine learn from data? See prediction, error, and repeated adjustment — machine learning explained without the jargon wall.
  5. 05What Is a Neural Network?What is a neural network, and how do neural networks learn? Explore weights, layers, and how networks recognize patterns — no calculus required.
  6. 06What Is Deep Learning?Deep learning explained: why neural networks are deep, what layers learn, and what becomes possible when representations stack.
  7. 07What Are Learned Representations in AI?Representation learning explained: how neural networks learn features, and how that differs from hand-built feature engineering.
  8. 08What Is a Transformer? How Attention WorksWhat is a Transformer, and how does attention work? Self-attention, why Transformers were invented, and how models predict what comes next.
  9. 09How Do Large Language Models Actually Work?How do LLMs work — tokens, next-word prediction, and how a language model generates text? Practical interactive lesson. Free, no signup.
  10. 10What Changes When AI Does the Work?Explore what changes the first time AI does the work instead of just answering questions — handoff, judgment, and staying in the loop.
  11. 11What Should AI Be Allowed to Touch?Explore connectors, permissions, and who decides what an assistant may touch when it’s linked to real data and accounts.
