Professor Intelligence
We already know your professor
Upload your course materials, and Cubby learns what your professor emphasizes, how they frame questions, and what earns points. Cubby may already have insights into your professor, and your materials make that understanding even more specific. That understanding shapes every brief, quiz, practice exam, and piece of feedback.
How it works
Cubby creates a personalized study system you can rely on from day one of the semester through finals. Powered by analyzing your professor’s teaching style, course materials, and past exams.


Professor-Specific Setup
Upload your outline, notes, slides, and past exams. Cubby adapts to your professor’s teaching approach, emphasis, and exam style, so your practice mirrors how you’ll actually be tested.


Study With Closed-System AI
Use Donna, Cubby’s AI teaching assistant, to ask questions and receive explanations grounded in your uploaded materials.


Practice All Semester
Prepare for cold calls, reinforce concepts with outline quizzes, and generate unlimited professor-specific practice exams with instant grading and feedback.
Blind Evaluation
Cubby beat the biggest AI models.
We had law students compare a thousand responses from Cubby, ChatGPT, Claude, and Gemini, without telling them which was which. Cubby’s answers won 63% of the time.

#1 overall among evaluated models.
Cubby’s advantage over ChatGPT was statistically significant.
- Cubby63%639-370
- ChatGPT44%153-191
- Claude36%120-212
- Gemini29%97-236
Students were shown two answers to the same legal question (one from Cubby, one from another model) and selected the stronger response without seeing the model names. Each model’s win rate is the percentage of its own matchups it won. Based on 1,000 blind comparisons, July 2026.
