Building Cortex — a behavioral AI system tackling one of the largest global productivity leaks: unconscious digital behavior. Cortex predicts and intervenes in user actions in real time, using proprietary behavioral data to interrupt compulsive scrolling and reshape human attention at scale.
I built Cortex after realizing how absurdly optimized modern apps are at hijacking attention. Most “screen time” tools just show stats after the damage is already done, they don’t intervene in the moment your brain is about to open Instagram, TikTok, X, etc.
So we built an iOS-native system that interrupts compulsive app opens in real time with friction layers, intentionality prompts, and behavioral design patterns inspired by neuroscience and habit formation.
The hardest part wasn’t the technology but the designing interventions that are effective without feeling annoying. We iterated heavily on timing, UX, and psychology to make Cortex feel premium, fast, and actually usable every day.
We’re early, but the vision is much bigger than “screen time reduction.” We think the next generation of consumer software won’t just maximize engagement but also optimize for cognition, focus, and human agency.
