HateBlocker is a free Chrome extension designed to enhance user experiences on YouTube and Facebook by filtering out toxic comments. Utilizing Chrome's built-in AI, it effectively identifies and hides harmful comments without ever sending data to external servers. Users can customize their experience with three sensitivity levels and specific categories of comments to filter, including personal attacks and hate speech.

The extension operates entirely on-device, ensuring user privacy by not collecting or transmitting any browsing data. It features a straightforward interface, allowing users to reveal hidden comments with a click and providing options for different display styles. With features such as per-platform toggles and a comment counter, HateBlocker makes it easy for users to manage their online interactions while maintaining a safe environment.
