HelperTeacherAI helps teachers grade paper exams by photo instead of by hand. How it works: 1. Photograph the answer key once per exam. 2. Photograph each student's answer sheet. 3. The app reads the marked answers and compares them to the answer key automatically. You get each student's score in seconds, without typing a single answer. Why teachers use it: โข No manual grading โ just two photos per exam. โข Works with multi-page exams and double-sided answer sheets. โข Student names and scores are never sent anywhere. Only the exam photos are sent for reading, and they are not stored on our servers. HelperTeacherAI is built for teachers who want their grading time back.
