GradeLab

GradeLab | Automated Handwritten Exam Grading | AI Assessment" is an AI-powered grading tool designed for teachers to digitize and automatically grade handwritten exams with human-like accuracy. It converts scanned answer sheets into digital data, applies AI-driven evaluation against rubrics or answer keys, and delivers detailed feedback and progress analytics to streamline grading and enhance teaching focus.

3. Detailed feedback reports. The system provides comprehensive student feedback, identifying strengths and areas for improvement.
4. Progress tracking & analytics. Real-time tracking of student performance across exams with data-driven insights to inform instruction.
