From the inside
Built inside the firms that can't afford to get it wrong.
Hey, I'm Charafeddine
I've shipped 60+ AI systems. The bottleneck was always human.
For a decade, I did that work where the stakes were highest, inside firms like PwC. I advised the boards, led the programs, and wrote the code myself.
Along the way, I kept seeing the same thing: brilliant people drowning in AI hype, armed with expensive tools they didn't know how to use.
So I started writing about what actually works.
New book · 2026
How to think with AI
Why the same tool produces genius for some and mediocrity for others. The difference was never the tool. It was the human operating it.
Judgment, taste, and verification, told through real scenes from inside real companies. Endorsed by Francesco Profumo and PwC's CMO. Out now, in English and French.

One idea a week, explored in depth.
Free. Every week.
I take one piece of AI noise and turn it into something you can actually use.
No prompt dumps. No hype. No "5 AI tools that will change your life." Just the thinking that makes a tool worth using.
80+ editions. 15,000+ readers. The letter people forward to their teams.
Published work
Papers, playbooks, code.
My courses aren't built on theory. They come from research I publish, code I ship, and systems I run in production.
Peer-reviewed papers on AI agent reliability, model behavior, and enterprise readiness.
Battle-tested playbooks from real enterprise deployments, not slideware.
The AI OS suite: open-source Python libraries for running trusted AI agents in production.
