Origin story

Why Gradiuz exists

Not a pitch deck. A 400-page textbook and two weeks to go.

I didn't need to read it a third time. I needed someone to test me on it.

G

Gab · Founder of Gradiuz

Still a student · still using it for every exam

The wall

Second year of uni, exams two weeks out. Gab had read the 400-page textbook twice - highlighted, annotated - and still had zero proof any of it would surface on exam day.

The hack

The fix was a tiny script: feed it the lecture PDFs, get practice questions back. Studying became answering instead of re-reading. Grades jumped. Friends asked. Then their friends did.

Still the idea

That script grew into Gradiuz, and the idea never changed: your material → active practice → in seconds. Your course, your exam, your notes - never a generic question bank.

Your notes in. → Active practice out. → Exam day, ready.

What we believe

Four simple rules that shape every feature we ship.

Active recall beats re-reading

Every feature pushes you to retrieve info, not just review it. That is what learning science says works.

Your material, not generic banks

Questions from your own PDFs and notes match your exam - no irrelevant textbook filler.

Fast enough for real life

Upload before class, practice at lunch. Study tools should take seconds, not hours.

Priced for students

A free tier to try everything, and paid plans that cost less than a single textbook.

Built for how you actually study

From uni exams to after-school practice - same product, different superpowers.

Med & university

Name every structure - not just recognize it

Upload an anatomy plate or lab diagram and cover labels with image occlusion. Hide organ names, vessels, or pathways and force yourself to recall them - the drill that sticks for exams.

Occluded image flashcards
Drill weak labels first

Younger students

Practice that feels like play

Turn notes into arcade-style games - match, race, and challenge modes that make revision fun. Same material as a quiz, but built for short sessions after school when focus is hard.
