PhobiaBlocker

PhobiaBlocker helps users enjoy a fear-free web-browsing experience: when you encounter sudden, alarming images of spiders or other real-world objects in chat apps or on social media, this extension can immediately block them. Powered by an ImageNet classification model, it analyzes <img> and SVG <image> elements locally and allows users to independently select which objects to block from an extensive list of real-world entities—such as insects, animals, and plants. All image processing occurs directly on the user’s device, with no browsing data ever being uploaded.

The extension offers both automatic and manual blocking mechanisms: users can enable quick blocking of spider- or insect-related images with a single click, or finely select dozens of real-world object categories through advanced options. Additionally, it supports configuring regular expression rules, adding whitelists of trusted websites, toggling between dark and light modes, and controlling the automatic blocker’s on/off status—balancing protection precision, system performance, and ease of use.

This tool is ideal for Chrome browser users who suffer from specific object-related phobias—such as arachnophobia or entomophobia—and who prioritize local privacy processing while requiring real-time image filtering capabilities.
