How Our AI Works
Our artificial intelligence analyzes your answers, identifies strong and weak areas, and automatically generates new questions at an appropriate difficulty level. The system creates explanations, hints, and personalized recommendations to help you understand the material and prepare more efficiently.
The platform does not use any official exam materials. All questions are generated by AI based on general testing principles and the typical structure of exams such as SAT and ACT.
The AI operates in real time by:
- evaluating each of your responses;
- selecting training examples;
- adjusting difficulty;
- creating a personalized learning path.
AI Content Policy
All questions, explanations, and tasks are generated using artificial intelligence technologies. The materials are not official exam questions and are intended solely for practice and skill development. We comply with OpenAI usage policies and ensure that all generated content:
- does not copy protected or licensed materials;
- matches the approximate difficulty of the exam;
- is educational and helpful;
- does not mislead users about the origin of the questions.
