About GradeCube

GradeCube makes the AI you already use actually useful for school. WORKS TODAY AT: University System of Georgia schools (Georgia View / D2L Brightspace). If your school is not on Georgia View, GradeCube will not have anything to read yet. More D2L schools are next, then Canvas. Want your school added? Email contact@sturdybridgesystems.com. You already use Claude or ChatGPT. The problem is they know nothing about your classes, so you spend half your time pasting in syllabi, slides, and assignment instructions just to ask one question. GradeCube fixes that. Install it, open your courses once, and from then on your AI assistant knows your whole semester. How it works, in about two minutes, once a semester: 1. Add GradeCube to Chrome and log into your school like you always do. 2. Click through your courses one time. GradeCube reads what your professors posted, around 15 seconds per class. 3. Paste one link into your AI assistant's connector settings. After that, every chat starts with your classes already loaded. What you can do once it's connected: - Ask anything about your classes and get a real answer. "What's the late policy in my stats class?" "Summarize chapter 7 from the slides my professor posted." It answers from your actual course material, not the internet. - See your whole week in one ask. "What's due this week?" pulls every assignment, quiz window, and deadline across all your classes, with the dates already worked out so the AI never has to guess what day it is. - Get real grade math. "What do I need on the final to keep an A?" comes back as an actual calculation from your real gradebook, with the work shown. - Make study decks from your own material. Ask for flashcards or a practice test on any chapter and get a deck built from your professor's actual slides, not generic textbook facts. The decks live in your GradeCube dashboard with flashcard, learn, and test modes, so you get the study-app experience built from your real class instead of a generic deck. - Open your own dashboard, no AI required. GradeCube gives you a personal dashboard that puts your calendar, deadlines, grades, and course materials across every class in one place, so your whole semester stays organized even when you are not asking the AI anything. - Find professor feedback you missed. "What did my professor say about my draft?" surfaces the written feedback and rubric scores buried in your submitted work. A study tool, with a clear line. GradeCube is built to help you understand your classes faster, not to take shortcuts through them. We drew the line in the code, not just the marketing. GradeCube cannot read or assist with live quizzes and exams; nothing in it reads an active attempt, and it only handles metadata like due dates and turned-in status. When it cannot actually read something, it tells you plainly instead of making something up. Your courses stay yours, never shared between students, never sold, never used to train AI. Honest about what works today. Right now GradeCube works with D2L Brightspace at University System of Georgia schools, connected to Claude or ChatGPT through your own account. More D2L schools are rolling out next, and Canvas support is on the roadmap after that. If your school uses D2L and you want in early, reach out. Your data, plainly. GradeCube runs in your own browser on the session you are already logged into, so we never see your school password. Your course content syncs to a private, per-student space on our server so your AI can read it, isolated from every other student. You can remove any course's data yourself at any time, and email us to delete everything you have synced.
