Prüfsim is an AI-powered writing and simulation application developed for users preparing for the TELC Schreiben exam. The application enables you to practice through tasks aligned with the TELC writing section and accelerates your progress by analyzing the texts you write. Realistic practice for TELC Schreiben Prüfsim offers writing tasks that match the TELC exam format. These tasks are prepared based on daily life, official correspondence, and different scenarios that may be encountered in the exam. Users can: • Solve writing tasks • Create their own letters • Practice at different difficulty levels The goal is not just to write, but to acquire the thinking skills aligned with the exam format. AI-powered writing analysis One of the strong features of Prüfsim is its AI-supported analysis system. After writing a text: • Grammar errors are analyzed • Sentence structure is evaluated • More accurate and natural alternatives are provided • An improved sample text is generated This way, the user not only sees their mistakes but also learns the correct usage. Training mode and simulation mode The application includes two different study modes: • Training mode: Focuses on learning. Errors are explained in detail, and the user is guided. • Simulation mode: Mimics the real exam experience. The user practices writing under time pressure.
