Users can input source questions from GMATClub and customize the difficulty level using adjustable band controls. The tool excels in providing clear explanations for the answers and options, making it a valuable resource for test-takers aiming to enhance their skills.

The application supports various text models from OpenAI and Gemini, allowing users to create questions that maintain the essence of the original while adjusting complexity. Harder questions challenge users with nuanced logic traps, while easier ones simplify the concepts.
