Sound familiar?
Asked ChatGPT about travel, work, and hobbies all in one thread - total mess
AI responses that are "not bad, but not quite..."
You know Claude, Gemini... but don't know when to use which
The real reason behind "not quite..."
The problem was asking one AI to do everything.
Planning, writing, reviewing - all dumped on ChatGPT. That's like telling one talented employee to handle accounting, sales, and planning all at once.
The solution wasn't "organization" - it was "role assignment."
One AI does everything
- • Endless threads piling up
- • Can't remember what was discussed where
- • Scattered, unsatisfying output
Assign roles
- • Use different AI personalities for different situations
- • Give names and roles to create specialists
- • Create together
What You'll Get
Using AIs with different personalities
ChatGPT, Claude, Gemini. Learn their personalities and when to use each one.
Setting up Claude Code
Escape the copy-paste nightmare of switching between browsers. Everything in one terminal.
The experience of AI becoming "someone"
Give an AI a name and role, and it generates its own appearance. Set it as your terminal background - always there with you.
Creating with an AI team
Planning AI, Writer AI, Editor AI. Create together with multiple AIs, each with their own role.

By the time you finish reading, it's already running
Not just knowledge - multiple AIs will actually be working together.

Reader Reviews
"Rather than asking a single AI for one-shot output, coordinating multiple specialized AIs produces far better results." This workbook lets you experience the future of AI collaboration firsthand. At $19.99, it's an incredible value for a weekend read.
