The prompt is never the bottleneck.
Your thinking is.
Learn what to think before you type, how to check what AI gives you, and how to decide with it, on any model. 23 lessons, 12 printable cards.
Same tool. Same AI. Same subscription.
Completely different output.
You've seen it. Two people use the same AI. One produces work that gets forwarded to the CEO. The other produces work that gets a polite "can you redo this?"
Same model. Same subscription. Same prompt format.
What separates them is the five minutes of thinking that happened before the tool was involved.
This course teaches you what to think before you click anything.
Five modules. 23 lessons.
One discipline.
A primer, then four layers. Each builds on the one below.
The Taste Gap
Why the same AI gives an expert and a beginner very different work, and how your expertise steers it.
The 5-Minute Rule
Four questions on paper before you open any AI, then a live demo with a timer.
Verification
Polished and correct are not the same thing. Separate the generator from the critic, match the review to the risk, and test the answers that matter.
Decisions
What to do when the AI gives you three options and you freeze: write to decide, calibrate your confidence, and know where your accountability starts.
Your Personal System
Build your Pre-Prompt Protocol and Post-Output Protocol. Customize for your role. Capstone: run both protocols on a real task and measure the before-and-after.
Hi, I'm Charafeddine.
I led AI rollouts for 4,000+ employees and have shipped 60+ AI systems. I'm an AI scientist and a professor, and I've trained 200+ professionals live since 2023.
4 minutes and 23 seconds. Real task. Real timer. Charafeddine runs the 5-Minute Rule on camera, start to finish, then shows what the AI produced from it.
Grounded in research, including CHI 2024 best paper on AI metacognition, MIT Media Lab on cognitive debt, Slamecka and Graf on the generation effect, and Kahneman on System 1 vs System 2.
You won't practice alone.
The course opens three months in the Engine Room, Cohorte's community of people who use AI at work every day. They bring real problems, compare what worked, and keep the method sharp long after the last lesson.
People doing the same work.
Operators, engineers, analysts and managers, from bootcamp alumni to course buyers. Ask how someone applied a lesson, compare notes, find who has already solved your problem.
Live, every other Monday.
An open Q&A on Zoom at 18:00 Paris time with Charafeddine, who teaches the course. Bring the prompt that disappointed you or the decision you're stuck on. Can't make it? Leave your question in the thread.
The Helpdesk.
Post a real question from your work. Charafeddine answers in writing, members add what worked for them, and every answer stays searchable for the next person.
You don't. The training rewarded it for agreeing with you. … Generate in one session, judge in a separate one, and ban “is this good?” as a prompt.

- 23 lessons across 5 modules, with 18 videos
- 12 printable protocol cards, including the Wallet Card for your desk
- Capstone with before-and-after measurement
- What's actually in this course?
- 23 lessons: a primer on the Taste Gap (why expertise matters more with AI), then four layers. The 5-Minute Rule (the discipline before you type), Verification (catching what polished output hides), Decisions (when AI helps and when it doesn't), and Your Personal System, where you wire it all together.
- Is this just a set of videos?
- No. 18 videos, written lessons and essays, and 12 printable protocol cards. Your purchase also includes 3 months in the Engine Room: a live Q&A with Charafeddine every other Monday, the Helpdesk where he and members answer questions in writing, and the people working through the same ideas. After three months, staying is optional.
- How is this different from The AI OS Course?
- The Thinking Stack is a shorter first step: the cognitive discipline before any framework. The AI OS Course builds the full system on top of it: your context, your method and your checks, on any model.
- Will this teach me to use ChatGPT or Claude better?
- Yes, indirectly. The course teaches the four cognitive habits that change what you ask, when you ask it, and how you read the output. The result is better work from any model.
- I already use AI every day. Will I learn anything new?
- If you already use AI and still feel your output is generic, this is the gap. The course is short on purpose: it's the foundation.
- Do I need a paid AI subscription?
- A paid ChatGPT, Claude, or Gemini plan helps but isn't required. Free tiers work for the lessons. The course is tool-agnostic.
- How long will it take?
- About 3 hours of video and reading, plus the exercises. At one module a week, four to five weeks. There's no deadline.
- Can my company pay for this?
- Yes. Email [email protected] with your company's details and we send a quote and an invoice. Bank transfer accepted.
- What's the refund policy?
- €97 courses are non-refundable once you open the course. Unopened, they are refundable in full within 14 days of purchase. Priced low on purpose. Technical issues with access? Email us and we'll fix them.
