Faculty Control

Cubby drafts.
You decide.

Think of it like a radiologist reviewing a scan: Donna drafts the grade, the redlines, and the per-issue feedback, and nothing reaches your students until you've signed off. Edit difficulty, rubric weights, and tone in plain English. Your standards, enforced at scale.

  • Claude

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.

Why Cubby For Professors

Generic AI knows the law. It doesn't know your course.

Generic AI can generate legal content, but it cannot understand the priorities, standards, and judgment that make your course distinct. Cubby is built to learn them.

General purpose AI

Generates generic, one-size-fits-all content

Creates questions and feedback from broad subject knowledge, without understanding what you emphasize, how you assess students, or what earns credit in your class.

  • Not grounded in your course materials
  • No sense of your question style or emphasis
  • Publishes without your approval
  • No view into where your class is struggling
  • Answers with no citation to your corpus

Frequently Asked

Everything you need to know before getting started

They are used to understand your course and only your course. Cubby uses your syllabus, slides, notes, exams, model answers, and rubrics to tailor assessments, feedback, and student support to the way you teach and grade. Those materials are not shared with students, other professors, other schools, or third parties, and they are never used to train a general model or improve another professor’s course. Your exams and answer keys can also be protected separately from student practice tools, so students cannot retrieve your past exam through Cubby. You can export or delete your materials whenever you need to. See the full commitment at cubby.law/professor-data-commitment.
