Teenagers launch Klausurbuddy for German exam preparation
Two teenagers have launched an AI platform that generates practice tests tailored to specific German school types. The tool uses prize money as initial capital to provide detailed feedback on student performance.
Lukas Tomasek, 15, and Paul Eierle, 14, founded Klausurbuddy, an AI-driven platform helping German students prepare for exams. The tool generates practice tests tailored to the specific federal state and school type, matching the format, operators, and point values of local exams. It launched publicly in September 2026 and has approximately 400 users. The founders won a €10,000 prize in a startup competition, which they registered as share capital for their UG limited liability company. The platform uses AI to provide specific grade predictions and detailed feedback on missing elements in material-based answers, aiming to correct minor errors rather than just providing solutions. The founders plan to use funds for API costs and initial marketing. They argue that AI should provide clear, sometimes negative, feedback to help students identify specific weaknesses, unlike general AI chatbots that may be overly encouraging. The founders noted that the company is now registered in the commercial register with the prize money serving as the initial capital.
