ModelMind: How AI Works

ModelMind teaches deep AI understanding in bite-size daily lessons. Not "how to use ChatGPT" — how AI actually works under the hood, why it fails, and how to think clearly with it.

WHAT YOU LEARN
• How language models are trained and what they actually do
• Why models hallucinate, and how to catch it
• Prompting that works because you understand the mechanism
• The difference between AI, machine learning, and LLMs — used precisely
• How to evaluate AI claims, products, and risks with a critical eye

HOW IT WORKS
• Short, focused lessons built from cards, diagrams, and interactive explanations
• Hands-on exercises: sorting, sequencing, matching, triage, comparisons, and decision trees
• Spaced progression across structured units — each concept builds on the last
• Clear sources for every claim, so you can go deeper

WHY MODELMIND
• Written for curious adults, not engineers — zero math background required
• Precise terminology: we never say "AI" when we mean "LLM"
• No ads, ever
• Works offline once lessons are downloaded
• Available in English and Korean
