SafeGrader
A grading assistant that protects student privacy — right on your Mac.
SafeGrader is a Mac app built for teachers. Pull a stack of student submissions out of Canvas — Word documents or PDFs — and drop them in. Before anyone (or anything) reads the work, SafeGrader uses your class roster to find and hide student names, ID numbers, and email addresses, so each piece is anonymous.
From there, SafeGrader grades each anonymous submission against your rubric. The grading is done by an AI assistant that lives right on your Mac — your students' work never has to leave your computer. If you'd rather use a cloud-based AI like ChatGPT or Claude, you can switch that on; only the anonymized version gets sent. Either way, the AI is locked to the point values you set, so it can't hand out a 7 out of 5.
Every graded paper is laid out cleanly on screen for review, with a score, a short explanation, and feedback for each part of your rubric. SafeGrader also writes a summary of the whole class, pulling out student quotes that struck it as insightful, ones that look like real problems, and ones that suggest the class is confused about the same thing. When you're ready, the whole package — the rubric, a privacy report, and the class summary — exports to a polished PDF.
