A Kwame Nkrumah University of Science and Technology student, Benjamin Etornam Abotsi, has created Prep AI, a free and simple tool that generates study questions from uploaded notes

It was not just a regular week for Benjamin Etornam Abotsi, a third-year Computer Engineering student at KNUST. He had just lost his best friend. The grief hit hard. The burial was near, and Benjamin found himself struggling to process it all.

“I didn’t know what to do. I was just moving around. I couldn’t settle. I had lectures, I had projects, and this happened.”

But instead of giving up, he did something different. On the evening of March 12, the night before the burial, Benjamin sat down with his laptop. He needed something to focus on, something that could help him, and maybe others too. That was when the idea for Prep AI came to life.

Prep AI is a tool that helps students’ study. You upload your slides or notes, and the tool generates questions from them. It then gives you answers, and if you get a question wrong, it explains why. The tool quickly became useful. Benjamin shared the link, and soon, over 1,000 students signed up. In just days, users had generated more than 50,000 questions.

“It felt good to see others use it. Even though I was going through a lot, it made me feel like I was doing something that mattered.”

He didn’t plan it for a long time. He didn’t write a big proposal. He just wanted something to help him focus and it ended up helping many more.

Feedback started pouring in. Students were excited. Many were using Prep AI during the exam season to test their knowledge and get quick answers. Some said it made studying easier. Others asked for more features. Benjamin has started collecting the feedback and plans to improve the tool after his exams. Students can log in via: https://preps.onrender.com/login

This is not his first tech project. He has also worked on an AI system to detect fraud in financial transactions.
