About PREPEUR
PREPEUR tells you if you're ready for your exam — and if not, what to study.
Our Mission
PREPEUR is an AI-powered exam preparation platform that tells you if you're ready for your exam — and if not, what to study. Every practice question is generated from your course materials and linked back to the exact source location.
We believe exam preparation should be directed, not blind. Upload your course materials, set your exam date, and PREPEUR shows you exactly where you stand — so you can focus on what matters: the topics that need work.
The Problem We Solve
Students prepare for exams without knowing if they're actually ready. Existing solutions don't help:
- •Blind practice — no way to know which topics you've mastered and which need more work
- •Generic AI tools — generate plausible-sounding questions with no link back to the source material; you can't verify them or go deeper
- •Pre-made study sets — rarely match your specific course materials
PREPEUR solves all three: upload your course materials, set your exam, practice with verified questions, and see exactly where you stand — topic by topic.
Who PREPEUR Is For
PREPEUR is built for the self-tester — the student who, before the real exam, wants to prove to themselves they're ready, and would rather find a weak spot now than in the exam hall.
It's exam-agnostic: a university final, a professional certification, a licensing exam — if you take it seriously enough to test yourself first, PREPEUR is the tool to do it with.
Where It Started
PREPEUR started with a study habit. As a Computer Science student at Kristianstad University, Erick used ChatGPT to drill himself before exams — useful, but every question had to be cross-checked against the textbook because the model couldn't show its work. The verification was becoming the work.
That experience drove his 2025 thesis on retrieval-augmented generation for educational content: could an AI system reliably generate and judge MCQs across complexity levels — from simple recall to higher-order reasoning — when grounded in real course materials? The work answered yes, with the right retrieval pipeline and the right models. PREPEUR takes a focused slice of that research and turns it into a product, anchored on the part the original habit was missing: every question, traceable to the page it came from.
What We Promise
Every question you see has passed a quality contract. Each one is traceable to a specific page in your materials. Each is judged for accuracy and pedagogy before it reaches you. When you answer, the same source grades you.
"If students must verify AI output, we've already failed."
