About gradionis

Gradionis is an automated grading platform that turns ordinary office printers and scanners into a fast, reliable multiple-choice grading system. Instructors print QR-coded answer sheets on any standard printer, students fill them in, and the sheets are scanned back in — by a desktop scanner or even a phone. Gradionis automatically identifies each sheet, reads the marked answers, and grades every submission against the answer key in seconds.

It is built for instructors, teachers, and academic departments who administer multiple-choice quizzes and exams and want instant, accurate results without expensive proprietary hardware or manual bubble-sheet sorting. Beyond raw scores, Gradionis provides item and distractor analysis, per-student and class-wide reports, and exportable grade files, so educators can focus on teaching rather than tallying.

Gradionis is developed by the gradionis team with a focus on privacy, accessibility, and compatibility with the tools schools already own. Student data stays isolated per instructor, and every answer sheet works with standard Letter, A4, or Legal paper. Whether you grade a ten-question quiz or a hundred-question final, Gradionis handles the scanning, recognition, and reporting so you can spend your time on what matters most: your students.
