Personal AI OS

THE REAL-WORLD SETUP

My Stack

The tools behind my Personal AI OS.

Not a wishlist and not a generic gear guide. These are devices, apps, training tools and everyday nutrition products that are actually part of my setup. Some generate data for the system; others simply make training, fueling and everyday execution easier.

Principle: products belong here because I actually use them — not because somebody pays to be listed. Current links are direct, non-affiliate links. If affiliate links or paid partnerships are added later, they will be clearly disclosed.
