Unlike screen-time blockers that punish you with friction, Pet Gatekeeper interrupts doomscrolling with a short video of YOUR own pet — not stock animation. Generate it on our site from one photo, install the Chrome extension to guard your feeds, and add the Win/Mac desktop app if you want coverage beyond the browser. First digital-wellness tool using personal emotional attachment instead of guilt, willpower, or hard blocks. Multi-pet cloud library, synced across every screen.
