A Cognitive Firewall for the Modern Mind.
"The screen is not hugging you back. You are holding a cold piece of glass."
FOHKASU is not just a website blocker. It is a psychological intervention tool designed to interrupt addictive digital habits by targeting the emotional and cognitive loops that drive them.
Most blockers treat you like a machine ("Block Site X for 30 minutes."). FOHKASU treats you like a human with emotions, regrets, and a fading future. It uses dark psychology and visceral design to break the dopamine loop before it starts.
-
Hyperbolic Discounting
We interrupt the immediate reward (e.g., TikTok) to force you to calculate the long-term cost — your future. -
Reward Prediction Error
By delaying the block for a few seconds, we create a "negative prediction error": the dopamine spike collapses into disappointment, weakening the learned reward. -
Memento Mori
FOHKASU calculates an estimate of how many weeks you have left and forces you to confront that number as a moment of reflection.
FOHKASU is designed to feel like high‑tech cognitive armor.
-
The Dashboard
Your control center: profile, statistics, and the Graveyard (relapse history). -
The Void (Blocking Screen)
The immersive blocking experience: screen fades to black, targeted messages, audio cues, and the Memento Mori display.
Example blocking screen content:
- 🛡️ SYSTEM ACTIVE
- Screen fades to black...
- Identity: Asagi (Parent)
- "If your child walked in right now, could you look them in the eye?"
- The Graveyard (Last 28 Days)
- 📉 Dopamine Crash Initiated
- 💀 🛡️ 🛡️ 🛡️ 💀 🛡️ 🛡️
- YOU HAVE 2,400 WEEKS LEFT TO LIVE.
- 🛡️ 🛡️ 💀 🛡️ 🛡️ 🛡️ 🛡️
- Don't waste this one.
- (💀 = Relapse / 🛡️ = Focus)
- (Audio: "Aria Math" plays softly)
-
The Hallucination Protocol
Before blocking a site, FOHKASU rewrites page text (titles, headers) into unsettling messages that speak to the subconscious. -
The Graveyard of Time
A visual calendar that marks each day you relapse with a 💀. Watch your life rot in real time if you fail. -
Auditory Horror
Uses "Aria Math" (a haunting orchestral track) to trigger a Pavlovian response of focus and melancholy. -
Identity-Based Warfare
The extension adapts to your identity (Parent, Student, Male, Female, etc.) and tailors messages to maximize psychological impact.- Example prompts:
- For Parents: "If your child walked in right now, could you look them in the eye?"
- For Men: "You promised to build an empire. Look at you now."
