📚 Evalora AI – Smart Evaluation & Personalized Learning Platform

Inspiration

Teachers spend countless hours manually evaluating answer sheets, while students often receive only marks with limited feedback. We wanted to build an AI-powered platform that not only automates evaluation but also helps students understand their mistakes and improve continuously.

Our goal was to transform traditional examinations into an intelligent learning experience where AI acts as both an evaluator and a personal tutor.
