how it works
A four-step loop. Designed to be uncheatable.
01
You reach for the app.
Tap Instagram or TikTok. Kael steps in first.
02
You type why you need it.
Just a short reason. “I'm bored” gets denied instantly.
03
Claude weighs it against your day.
Schedule, deadlines, and goals are the context. Claude returns yes or no.
04
Approved? Time-limited. Denied? You reflect.
Approved access is time-boxed. Denied means a 20-word reflection.
