Here’s why the platform focuses on simplifying revision, improving retention, and reducing study stress.
For most teenagers, school ends with homework, sports, or scrolling through social media. But for 16-year-old Karl Hechema, evenings slowly turned into brainstorming sessions, coding experiments, and revision calls with stressed classmates trying to survive one of France’s toughest school examinations.
Today, that small idea has evolved into PrépaDNB, a free AI-powered study platform now used by more than 5,000 students across over 40 countries.
The Dubai-based Egyptian student from Lycee Francais International AFLEC built the platform after realizing that many students preparing for the French Brevet examination were struggling with revision, retention, and access to reliable study resources.
What began as helping friends over Zoom eventually became a full educational platform powered by artificial intelligence, personalized quizzes, revision tools, and student-first learning systems.
A Problem Hidden Inside Everyday Student Stress
Karl’s idea did not come from a business plan. It came from the frustration he kept seeing around him.
While preparing for the Brevet examination himself last year, he noticed that classmates constantly complained about the same problems. Many did not know how to revise properly. Others were overwhelmed by scattered study materials online that were not designed for the French curriculum.
After repeatedly helping friends prepare for exams, Karl found himself conducting regular revision sessions online.
Eventually, a bigger question emerged: how could the same support reach students without requiring him to personally teach every session?
That question became the foundation for PrépaDNB, launched in October 2025.
Instead of building another generic study website, Karl focused on creating a centralized learning platform designed specifically around the real habits and struggles of students.
The platform combines:
- Revision sheets
- Worked exam papers
- Flashcards
- Quizzes
- Podcasts
- Personalized AI-generated practice tests
The structure reflects the exact methods Karl himself used while preparing for the exam.
More importantly, the platform remains free.
For him, the purpose was always accessibility before monetization.
How AI Helped Build the Platform
Karl had already experimented with simple websites before launching PrépaDNB, but building a fully functional educational platform initially felt overwhelming.
Artificial intelligence changed that.
Using AI-assisted coding tools, he began translating ideas into working systems one page at a time. Instead of relying on traditional development teams, he taught himself how to structure workflows, troubleshoot errors, and continuously improve the platform through experimentation.
The learning process became much deeper after launch.
Building the site was one challenge. Managing real users was another entirely.
As students from different countries started using the platform, Karl had to solve device-specific bugs, fix performance issues, improve usability, and constantly adapt the system based on feedback.
That experience taught him an important lesson about technology products: platforms are never finished. They evolve continuously alongside the people using them.
The project later expanded into mobile applications for both iOS and Android, further increasing accessibility for students preparing for exams on phones and tablets.
Why the Platform Focuses on Simplicity and Retention
One of the strongest aspects of PrépaDNB is its understanding of student psychology.
Many education platforms overwhelm users with too much information, complicated systems, or rigid learning structures. Karl approached the problem differently because he understood the emotional side of studying firsthand.
The platform focuses heavily on reducing stress and improving retention through simplicity.
Its AI tools generate personalized quizzes tailored to each student’s progress, helping users focus on weak areas instead of wasting time revising everything equally.
The revision formats are intentionally short, practical, and familiar to students preparing under pressure.
That matters because exam preparation is often less about intelligence and more about consistency, confidence, and clarity.
By simplifying revision and organizing learning into accessible formats, the platform helps students feel more in control of the process.
Growing Up in the UAE Shaped the Vision
Karl believes his environment played a major role in shaping the project.
Having spent his entire life in the UAE, he says the country’s culture of innovation, ambition, and technology made entrepreneurship feel natural rather than intimidating.
In his view, the UAE creates conditions where young people are encouraged to build ideas instead of waiting for permission.
That mindset became especially important while developing an AI-based platform at such a young age.
The country’s strong investment in technology and youth empowerment helped normalize the idea that students could create meaningful products with global reach.
For Karl, Dubai was not simply where he lived. It became the environment that allowed the project to exist at all.
Balancing School and Entrepreneurship
Despite the platform’s rapid growth, Karl insists that academics remain a priority.
Managing school, sports, extracurricular activities, and a growing educational platform requires careful time management and structure.
Rather than seeing entrepreneurship and academics as competing goals, he views them as complementary disciplines that strengthen each other.
That balance reflects a broader shift happening among younger entrepreneurs globally. Many student founders today are learning to build projects while still navigating school life, using technology to solve problems they personally experience.
Karl’s journey reflects that new generation of builders.
What’s the next
PrépaDNB may have started as a student helping classmates revise for exams, but its growth now points toward something larger.
The platform represents how AI can be used not only for automation or business efficiency but also for educational accessibility and personalized learning support.
Karl hopes to continue expanding the platform into more schools while helping students feel less overwhelmed during exam preparation.
His story also highlights a wider reality shaping the UAE’s youth ecosystem: when young people are given the right tools, support systems, and environment, they often build far beyond what anyone expects.
At just 16 years old, Karl Hechema turned a common classroom struggle into a global educational platform reaching thousands of students.
And remarkably, it all began with one simple question asked repeatedly by classmates: “How do I revise properly?”
