Students forget
KeptGone in a year
Within a year, students lose a quarter to a third of their basic science knowledge.² In organic chemistry, they keep missing questions built on general chemistry they already passed.³
memoryOS Education · for higher ed
Foster Learner Independence,
Not AI Dependency
memoryOS teaches students the Mind Palace, the memory technique world champions use, as a 3D game. They remember more with less cramming, and keep it long after the final exam.

Gateway courses that build intellectual autonomy
Give students memory they own, free from AI dependence.
AI often sounds right when it's wrong. A student who hasn't learned the material can't tell.
AI helps in practice, hurts on the exam
Practice
Exam
48% better in practice17% lower on the exam
Nearly 1,000 high school students practiced with ChatGPT. Without it, they did worse and didn't notice.⁴ University students with unrestricted AI use forgot faster too.⁵
They can't catch AI's mistakes
You can only spot an error in something you know.
People who trust AI more apply less critical thinking to its answers.⁶ In a UK study, younger adults leaned on AI the most and scored lowest on critical thinking.⁷
Our hypothesis
What we think helps: memory they own.
We think students who learn course material this way will remember more, do better on tests, think more critically and stay in their gateway courses. We're looking for faculty to help us test that.
Reducing attrition
Could improving knowledge retention reduce attrition?
Students who don't return after their first year are much more likely to have struggled in gateway courses like chemistry, calculus and accounting.⁸ If students hold on to what they learn, more of them may pass and stay enrolled. Our pilot is designed to find out.
About half
of students who didn't come back for a second year had a D, F, W or I in a gateway course⁸

He had an average memory and forgot most of what he learned at school. Then he found the memory palace in a library book. Today he teaches it in every memoryOS lesson.

Reviews
What students say about memoryOS
Real reviews from the App Store and Google Play. We picked the ones about school and studying.
I am a university student studying history and the skills learned in this app have aided me in deepening my learning to a degree I didn't realize I needed… If you want to be truly educated, you need to remember many things, and this app will give you the tools to remember anything.

Aspiring teacherGoogle Play
I love this method of learning. As an aspiring teacher I hope to try and apply these methods to help the students learn better. As for myself, already I notice huge improvements in my memory.

I'm a law student. Remembering details and maintaining focus are key to success. This app helps me everyday to learn new knowledge, new memory skills, and to sharpen my attention to detail.

As a medical student… I loved this app so much, it really helped me.

Looking backApp Store
In school they expect everyone to absorb everything at the decided pace and in whatever teaching style the instructor prefers. They don't teach you how to effectively learn though… The practices in this app fill in the missing gap by teaching you to remember by creating personal connections to the thing you need to remember.

Looking backApp Store
It's amazing to be able to remember all kinds of facts and names. I wish I'd known about this at university.
