Students from leading universities study with MasteryAI
No paid hype. Just genuine feedback from people using the app every single day.
"I used to spend hours every Sunday typing notes from 60 slide lecture decks. Now I upload the lecture audio and slide PDF, test myself with practice quizzes, and feel ready for exams without burning out."
Pre-Med & Molecular Biology • UC Berkeley
"What sold me is the Feynman mode. When I explain a hard algorithm out loud and it immediately points out the exact step I missed, it sticks in my head for good. It feels like having a patient tutor right on my phone."
Computer Science & Math • Univ. of Michigan
"Most note apps stop at basic summaries that miss the details. MasteryAI extracts definitions and key holdings into question flashcards so I can quiz myself before seminar discussions."
Law & Public Policy • Georgetown Law
