You can sit at a desk for ten hours and still lose the afternoon in silence — eyes on the screen, hands on the keys, mind already gone. App timers and blockers only see the window that was open; they never see the moment attention left without a tab switch. We build the instrument for that moment: a dry-EEG insert that sits in the earpad of the headphones you already wear, reads one around-ear channel of real brain signal, and scores an engagement index — β over α plus θ, after Pope et al. (1995) — from 0 to 100 against your own baseline while you work. When the number holds, you keep the block. When it falls, you stop faking it. That is the whole product for now: not a medical device, not a cure for ADHD, not a promise that hardware will make you ten times better — just an honest score so a founder or an engineer can tell, without guessing, which hours were real. We are Inky and Elijah. We would rather under-claim and be right than sell another dashboard that cannot see the brain.
