Getting Started in the AI Era

Friend, the pace of AI over the past two years has left no room for hesitation.

I’m a trader with 10 years of experience in the stock market, and I don’t know how to code. But starting from early 2024, I began using ChatGPT, and now I use Claude Code daily to read notes in Obsidian, Codex to automate my computer, and Skill to solidify workflows. I’ve gone through all of this from a complete beginner’s perspective—stepping into pitfalls, writing tutorials, and integrating it all back into my workflow.

This book strings together 27 AI tutorials I’ve written over the past year along a single thread. It’s not about technical principles—it’s about how someone who can’t code can actually put these tools to work.

AI tools evolve fast, so…

⚠️ The screenshots, commands, and workflows in this book may differ from the latest versions by the time you read them.

I will continuously revise:

  • If there are major updates, I’ll sync them to the PDF. Buyers can always contact me for the latest version (or the original Obsidian version).
  • Ask directly in the Q&A group. I use these tools daily and will follow up on changes as soon as they happen.

How to read

Read by the main thread:

  • Part 1: Foundations – AI large models, mainstream tools, registration and payment, Markdown—understand what you’ll be using.
  • Part 2: API – API, tokens, caching—technical concepts you need to get hands-on.
  • Part 3: Power Tools – Claude Code, Codex CLI, Codex App, and various new features—hands-on with mainstream tools.
  • Part 4: Advanced – Skill, MCP, Hook + PUA mindset—keys to using AI more deeply.
  • Part 5: Practice – Bilibili to text, DeepSeek with Claude, Open Minis—concrete, reproducible examples.
  • Bonus – Heavy tools like N8N—you probably don’t need them.

Read on demand:

  • Browse the table of contents for the pain points you want to solve most (e.g., how to use Claude Code, how to write a Skill, how to set up an API relay).

Follow along:

  • Configure things on your own computer as you read—it’s more efficient than reading ten times.

Who this book is not for

  • ❌ Advanced AI users (those who have been using Cursor, Cline, or Aider for over a year).
  • ❌ Those who want an out-of-the-box solution and aren’t willing to spend time configuring tools.
  • ❌ Those expecting a quick fix to make thousands a month with AI after reading.

I’d rather sell fewer copies than waste your money.
