Blocks distracting sites until you solve a math or coding puzzle. Includes a tedious emergency unlock. What happened the last time you visited a distracting site like reddit? First you open one tab. After forty minutes (and -10 IQ points), you catch yourself wandering the internet like a lost soul after an all-nighter in Las Vegas, with no memory of where you were going or how you got here. You didn't plan for this. Nobody ever plans for this. Your brain is weaker than the algorithms. Instead of exploring the stars, fixing our environment, or curing disease, humanity has deployed our finest math geniuses to addict brains like yours with online content. We all reach for distracting sites as a physical reflex and you have no chance. So we take the approach of the Sphinx, making you solve a riddle before you pass: - If a gate on distracting sites is just a blocker, it's so annoying that people eventually disable it. Sphinx's questions are intentionally solvable with modest effort. Better to have a speed bump than a wall that you'll eventually tear down. - Our brains are getting roasted by algorithms, just as we're also eroding our cognitive abilities with AI. So the questions force you to do a small amount of real thinking in the form of math or coding. Doomscroll less, and train your brain more.
