Lecture AI Assistant is an AI-powered educational platform that helps students transform their lecture files into an interactive study experience. The system supports multiple file types such as PDF, Word, PowerPoint, images, and audio, and uses technologies like OCR, speech-to-text, and RAG to extract and understand content. It allows students to ask questions, generate summaries, create flashcards, take quizzes, and identify weak areas, all within a structured personal study library.
