AIUB Portal+ is a powerful Chrome extension designed to enhance and modernize the AIUB student portal experience. It transforms the default system into a more intuitive, efficient, and student-friendly interface by adding advanced filtering, real-time insights, and clean data visualization. The extension introduces features like smart course filtering with clash detection, live class schedule timers, detailed grade and GPA breakdowns, financial summaries, and curriculum progress tracking. It also includes a redesigned global navigation system for seamless access across all portal pages. Built using Vanilla JavaScript (no external dependencies) and Chrome Extension Manifest V3, the project focuses on performance, modular architecture, and real-world usability. All data processing happens locally in the browser, ensuring complete privacy and security. This project solves real problems faced by students by simplifying course selection, academic tracking, and daily scheduling within a single unified interface.
