Stop Porn is a browser extension engineered to help users prevent access to pornographic content by automatically classifying images on a webpage. When you visit a site, the extension fetches and analyzes the images, and if it detects five or more pornographic images, it blocks the page. The image classification process happens entirely on your device, ensuring no data is transferred outside the extension. The extension has been tested on various well-known adult sites, showing high effectiveness in blocking them. Some sites might require additional interaction, like scrolling or refreshing, for successful monitoring.
