GradeHQ is a private, open-source grade calculator for college students. Unlike classic tools that force you to manually type in every percentage weight, GradeHQ uses AI auto-fill. Just drop in a syllabus PDF and/or Canvas screenshot, and it instantly maps out your course categories and scores. Pick a target grade, and it solves for the exact score you need on what's left. It runs 100% locally in your browser storage, no accounts, no databases, and zero tracking.
