Abstract
This paper introduces SmartPen, an intelligent, web-based system that automates the evaluation of handwritten
answers using Optical Character Recognition (OCR) and semantic similarity models. It integrates Tesseract OCR for convertingscanned scripts into text and leverages Sentence-BERT for context-aware semantic comparison of student responses with modelanswers. SmartPen provides educators with an interactive Streamlit-based interface to upload question papers, extract or inputmodel answers, and evaluate student submissions using cosine similarity scoring. The system supports real time evaluation,manual verification of OCR output, and downloadable scoring summaries. Through AI-driven semantic understanding,SmartPen offers an accurate, scalable, and unbiased approach to assessing subjective answer scripts in academic environments.
