I started playing around with Gen AI recently and, truth be told, I got more than a bit obsessed and enthused. For weeks I’ve been tinkering, training, and testing — late nights, too many coffees, a few Heinekens too, chasing the idea that AI could actually be life-useful, not gimmicky or too quick to spout advice without understanding the nuances of a situation.
After a number of resets, I’m excited to finally share it with you: Sakfucius GPT — my very own customized AI, trained on the same principles, stories, and strategies that shape my books, blogs, and work.

👉 You can try it here: sakfucius.com/gpt
(or just hit the link in the top header at sakfucius.com).
So what’s it for? Think of it as a mix between:
- A coach who pushes you to escape average.
- A strategist who helps you cut through the noise in business.
- A writing partner who makes your ideas sharper.
- A bartender who asks just the right question at the right time so you can think things through.
If Siri is a GPS telling you when to turn, Sakfucius GPT is the friend in the passenger seat — coffee in hand, pointing out a smarter route, maybe cracking a joke when you’re overthinking, and reminding you not to miss the scenery.
I’ve built it to be practical, principle-driven, and always candid — hopefully never fluffy, never fake. Whether you want to refine a big presentation, stress-test a business idea, or just get a nudge in the right direction, it’s here for you.
I’d love for you to give it a spin. Play with it, push it, see what it can do. And please — send me your feedback. This is an experiment, and experiments get better with friends involved.
Thanks for playing — and for being part of the ride. What a great time to be alive.
