Frequently asked questions

SuperGrader achieves 99%+ accuracy on multiple choice, short answer, and math problems. Our AI has been trained specifically for educational content.

SuperGrader works with multiple choice tests, math worksheets, short answer quizzes, fill-in-the-blank assignments, and handwritten work. No special answer sheets required.

Yes! Create custom answer keys, set partial credit rules, and adjust grading standards to match your teaching style.

Your data is encrypted in transit and at rest, and student names and grades are encrypted again in our database. It is never sold, never used for advertising, and never used to train AI models. To grade a paper we do send it to our AI provider — that is how the grading works, and our Privacy Policy sets out exactly who receives what. You can delete any grade, or your whole account and everything in it, at any time. On FERPA: it binds schools rather than vendors, so signing up here is not your school's approval. Check your district's policy before uploading student work.

Review and adjust any grade in one click — you always have the final say on every score. Your correction sticks: later recalculations leave a mark you have changed alone. Grading also flags low-confidence answers rather than quietly scoring them, and your corrections are never used to train any AI model.

No downloads required. SuperGrader works directly in your web browser on any device - phone, tablet, or computer.

Yes! Export grades to CSV and import directly into Google Classroom, Canvas, PowerSchool, or any gradebook system.
