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.
01Preface
02AI Tool Map: Which Tool Should Handle Which Kind of Work?
03Do Not Rush to Spend: What to Buy and What Not to Buy
Professionals making Gemini their primary tool — especially anyone already living in Gmail, Docs, Sheets, and Drive.
Complete sign-up and plan selection, master the machinery that is Gemini's alone (Gems, NotebookLM, the Chrome sidebar), and handle email, data, presentations, writing, and long documents across Gmail, Sheets, Slides, Docs, and Drive.
01A Practical Guide to Gemini: Getting the Most Out of Google's AI
02Free / AI Plus / AI Pro / AI Ultra, and How They Stack with Google Workspace
03Models and Modes: Choosing Between Flash, Pro, and Deep Think
People who are already fluent with chatbots and want to take their first step into agents, then learn to use and create Skills.
Understand how agents and Skills relate, install and judge existing Skills, and have an agent help you write your first Skill that triggers reliably and passes its tests.
01Where Are You Now? The Boundary Between Chatbots, Workflows, and Agents
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.
Draw the line between Cowork and Chat, run the full authorize–plan–approve–accept loop, connect folders, connectors and the browser, and use five worked cases to turn everyday work into tasks that can be delivered again and again.
01You Already Know Claude Well. Why Has It Not Saved You Time?
02What Is Cowork? The Boundary Between It, Chat, and Claude Code
03Which Work Should Go to Cowork? Four Criteria for Screening Tasks
