Is Cubby effective? What results have students seen?

Yes. 90% of users finished in the top half in their classes last year. 55% finished in the top 20%. 2Ls saw an average GPA increase of 0.25 compared to previous semesters. Cubby is effective because you're not studying the law in the abstract. You're studying exactly how your professor teaches and tests it.

What does it mean that you already have data on my professor?

That's Cubby Memory: anonymous, vetted, aggregate patterns drawn from study materials students shared with Cubby in prior years. We've already analyzed real course materials from your professor's classes to understand how they teach, test, and grade, and that intelligence powers everything you use. Your own uploads make it even more accurate, stay private, and are never shared with other students. Learn how it works at /memory.

How does the top-half guarantee work?

If you use Cubby consistently during the fall semester and don’t finish in the top half of your class, we’ll refund every dollar. We’re confident in the results because we’ve seen how students perform when they study with Cubby. 90% of our users finished top half last year, so we’re confident enough to put our money behind it.

What happens when I upload data? Is it shared with other Cubby users?

No. Everything you upload is private to your account and never shared with other students, even if they're in your section or at your school. Uploading your materials to Cubby is no different than storing them in Google Drive. Cubby builds your workspace from only the documents you provide, and your data stays fully isolated at all times.

Does using Cubby violate my school's honor code?

No. Cubby is a study tool that helps you practice and prepare. It doesn't complete assignments or generate work you can submit. Some schools have specific policies around uploading professor materials to third-party tools, whether that's Cubby, ChatGPT, or NotebookLM. We recommend checking your school's honor code to understand what's allowed. If your school restricts uploading professor materials, Cubby works well with your own notes and outline. For our full stance, read Cubby's Academic Integrity Policy at /honor.

Frequently Asked

Everything you need to know before getting started

ChatGPT and Claude know the law. Cubby knows your class. You're graded by your professor, on a curve, on the specific rules and frameworks they teach and a general AI will confidently give you the general rule even if your professor tests a different one. That costs points. Cubby trains on your professor's actual materials, past exams, and model answers so you're not practicing Contracts, you're practicing your professor's Contracts exam.
