Attention Guardian AI

Online learning platforms are widely used for education, but frequent advertisements distract users and reduce learning efficiency. This paper presents Attention Guardian AI, a Chrome extension that detects advertisements and replaces them with study tips and interactive quizzes. The system uses DOM manipulation and MutationObserver for real-time ad detection and analyzes webpage content to provide relevant educational material. AI integration enables personalized content generation, while offline support ensures continuous functionality. Additionally, user activity is tracked and visualized through a dashboard. The proposed system enhances focus, improves productivity, and promotes active learning.
