Senik: One Mental Model a Day

Mental models are small lenses through which experienced people see the world. The sunk cost fallacy. Occam's razor. Simpson's paradox. Each one is a short explanation of reality that works exactly when ordinary intuition fails.

Senik is an app with one such model a day. Not a reference — an editorial column: a concrete real-life scene, the underlying principle, an interactive scenario with voting, and one small action for today.

INSIDE
• 30+ thinking models — cognitive biases, mental models, paradoxes, thought experiments
• Each card is a 2-3 minute read
• Interactive scenarios with global voting stats (MIT Moral Machine, Harvard surveys, and more)
• Depth levels — swipe up to unlock biochemistry, information theory, philosophical commentary
• Streak mechanic — a simple daily ritual
• Save, history, search
• Bilingual: Russian / English

WHO IT'S FOR
• Founders and entrepreneurs — for decisions with high cost of being wrong
• Product managers and consultants — for hypothesis testing
• MBA students and educators — for systems thinking
• Anyone reading Kahneman, Taleb, Munger, Popper

WHAT MAKES IT DIFFERENT
Unlike reference apps for biases, Senik is editorial — one card a day, original copy. Unlike book summaries (Blinkist, Headway), this is original content, not rehashed chapters.

Works offline. Subscription unlocks all depth levels, saves, history. Without subscription — one card a day free forever.

Qaizo Studio is building a series of apps in this niche. If you enjoy Senik, look for upcoming apps on cognitive biases, paradoxes, and thought experiments.
