AI Foundations
¥39 · Lifetime access
Beginners who want a clear understanding of core AI concepts, capability boundaries, and basic safety before using AI at work.
Understand LLMs, tokens, context windows, hallucination, privacy boundaries, embeddings, multimodality, reasoning models, agents, model size, and open vs. closed models — and use them to make real tool decisions.
01What an LLM Actually Is: A Very Good Guessing Machine
02How It Was Trained: Pre-training, Fine-tuning, and RLHF
03Tokens: What AI Measures In, and What You Pay In
People already using ChatGPT, Claude, or Gemini who get inconsistent answers and want a reliable way to state what they actually need.
Master CO-STAR, chain of thought, few-shot examples, and constraint lists; control output formats; and build your own AI assistant with system prompts.
01Chapter 1: What Is a Prompt?
02Chapter 2: How to Write High-Quality Prompts—Four Techniques That Put AI to Work for You
03Chapter 3: How to Use Prompts in Different Scenarios—and What They Cannot Do
Professionals ready to put AI into daily work but not yet settled on a product — and anyone already using one who wants the underlying method.
Judge which category of tool a task calls for and pick the right one within it, write and reuse prompts and system prompts that hold up, and get started fast with images, video, voice, AI search, translation, knowledge bases, and meeting assistants.

Claude Cowork Practical Guide
Advanced users who are already fluent in conversation with Claude but have never had it deliver a finished piece of work — people who want to hand off the filing, research, weekly reports and follow-ups that eat their day.
