About GradeCheck
Know where you stand before your grade comes back.
GradeCheck gives you an AI estimate of your grade on work you've already submitted to Canvas or Gradescope, plus clear feedback on what's strong, what a grader will likely mark down, and how to improve. Once your work is graded, it explains where every point went.
HOW IT WORKS
Open an assignment you've handed in. GradeCheck reads the assignment, the rubric, the syllabus and your submission, then shows an estimate next to the title. Click it for the full breakdown:
- A score on the assignment's own point scale
- Strengths and likely deductions
- Feedback for each rubric criterion
- Flagged passages highlighted right in your typed submissions
It also learns from how your instructor has graded you earlier in the course, so the estimate matches how they actually grade.
WHY STUDENTS USE IT
- Catch weak spots while there's still time to resubmit or ask for help
- Understand a grade instead of just seeing a number
- Learn what your instructor values before the next assignment
PRIVATE BY DESIGN
GradeCheck is read-only. It never edits or submits anything. It has no servers and no account to create. You add your own free Google Gemini API key once, and your key and results stay in your browser.
WORKS WITH YOUR SUBMISSIONS
GradeCheck reads typed answers and uploaded files, including scanned and handwritten work. If a file can't be read, it tells you which one and grades the rest.
AN HONEST NOTE
These are AI estimates, not your grade. They can be wrong. Treat the feedback as a second read of your work, not a verdict.
