Making world-class education accessible to every learner, everywhere.
PrepGraph combines artificial intelligence with proven learning science to create personalized tutoring experiences that adapt to each student's unique needs, pace, and learning style. We believe that with the right support, every student can achieve mastery.
In 2022, our founders—a cognitive scientist, an AI researcher, and a former high school teacher—witnessed firsthand the limitations of traditional education:
What if we could combine: The personalization of a private tutor, the scalability of technology, the effectiveness of evidence-based learning science, and the accessibility of a mobile app?
PrepGraph was born.
Every product decision starts with: "Is this best for student learning?" If the answer is no, we don't do it. We measure success by learning gains, not engagement tricks.
Quality education shouldn't be a luxury. We price PrepGraph affordably, offer financial aid, and work with schools to serve underserved communities. Education is a right, not a privilege.
We never sell student data. Ever. Your learning data is used only to personalize your experience. We're COPPA, FERPA, and GDPR compliant—not because we have to be, but because it's the right thing to do.
We don't chase trends. Every feature is grounded in learning science research and validated with real students. We publish our findings openly and contribute to education research.
We're open about how PrepGraph works, what data we collect, and why. We admit when we don't have answers. We share our roadmap and listen to user feedback.
Learning science evolves. Technology improves. We commit to relentlessly making PrepGraph better—more effective, more accessible, more empowering.
