Mr Z
An AI Coach for Accountability

Why something this small works
Accountability doesn't need to be elaborate to work. A consistent weekly check-in creates a small, reliable hit of motivation that compounds over time, the same mechanism behind most habits that actually stick.
Why this was built in deliberately
This isn't a side feature, it's a core belief behind how Mr Z works. Small, regular accountability beats sporadic intensity for most people trying to build a lasting habit.
