online but want to stay human.

AI’s giving you time back. less repetitive work. fewer meetings. more time throughout the day.

but here’s the flip side— more free time, more chances to get distracted. and there are factories of people trying to make you addicted & it will constantly get worser.


instagram. tiktok. youtube. not evil. just default. and default kills depth. you don’t need more hacks. you need frictions.


we don’t block apps.
we make them just hard enough to rethink the impulse just for a price of a coffee.


we’re not a big corp. just rebels fighting for your focus—one friction at a time.
