AI summary — side by side with the source

Source page numbers, plain explanations and must-memorize points.

LRU evicts the least recently used page. p.5
With FIFO, faults can increase even with more frames (Belady). p.6

Flashcards

AI tutor — grounded in your materials

Answers based on the materials you upload.

Why does Belady's anomaly only happen with FIFO?

FIFO only looks at arrival order, so with more frames frequently used pages can get pushed out first. LRU is a stack algorithm, so it's fine.

For every moment of exam season

These examples are reconstructed from real use cases.

“400 slides, 3 days before the exam. It saved me”

I skimmed the summary for the big picture, then just kept cycling the quizzes. One less all-nighter.

Harvard Junior, Economics

“My professor talks way too fast to take notes”

I just hit record and the transcript builds itself. After class the summary shows exactly what I missed.

Stanford Freshman, Computer Science

“I used to get stuck on every research paper”

It pulls out the research question, methods and limitations as cards. Lab meeting prep takes half the time.

MIT PhD student, EECS

“Three deadlines landed in the same week”

I pasted in the assignment brief and got a checklist, so I never wasted time deciding where to start.

Yale Sophomore, Political Science

“I forget things no matter how many times I review”

It only shows the cards due today, so I do 15 minutes on the train. Got through pharmacology this way.

Princeton Senior, Molecular Biology

“When the exam countdown makes me anxious”

Seeing the D-day pace and doing just today's share takes the edge off. Small thing, big difference.

UC Berkeley Sophomore, Psychology

“No past papers for this class, but the practice questions hit”

I added the exam materials, worked through the predicted questions, and similar ones showed up on the final.

Columbia Junior, Mechanical Engineering

“When stats class broke my brain”

I ask the tutor to re-explain using my own lecture slides, and it uses the same wording as the course.

UCLA Sophomore, Statistics

“Making a mistake log for circuits was a chore”

Missed questions collect on their own. The night before the exam I just redid those.

Michigan Sophomore, Electrical Engineering

“Finally used all those photos of my notes”

I uploaded handwritten pages and it read them better than I expected. Scattered notes, one clean notebook.

Oxford Second year, History

“Flashcards are the best for anatomy terms”

No making cards by hand. They come back right when I'm about to forget, so it sticks.

Cambridge Second year, Medicine

“I used to run out of time just summarizing”

I let it do the summarizing and spent my time on problems. First time I reviewed twice before an exam.

Imperial First year, Chemistry

“Great for sharing notes in group projects”

I sent the summary link and the meeting worked even though nobody had done the reading, haha.

King's College London Final year, Geography

“When the theories wouldn't connect”

The mind map puts thinkers and theories on one page, so essay questions feel a lot less messy.

LSE MSc, Social Policy

“Juggling five courses in finals week”

It tells me how much to do per course today, so I stopped wasting time making schedules.

ETH Zurich Bachelor's, Computer Science

“Coming back after a gap year, totally rusty”

I re-uploaded my first-year materials and went through the concept cards. Caught up fast.

TU Munich Bachelor's, Industrial Engineering

“Surprisingly useful for lab reports”

I paste in my draft and it flags what's missing for each rubric criterion. It doesn't write it for me, which I like.

University of Amsterdam Bachelor's, Biology

“Studying from slides in a second language”

It summarizes English slides into clear key points, so prep for class takes ten minutes.

NYU Junior, Business
