Deep Study AI Agent uses OpenAI’s GPT models to process user-provided text or documents, extract key concepts, and generate study aids. Users upload lecture notes, PDFs, or text files, and the agent produces concise summaries, sets of flashcards, multiple-choice quizzes, and targeted practice exercises. It also offers configurable difficulty settings and contextual hints. The modular design allows extensions for new content types and prompt templates, making it flexible for various academic subjects and self-study workflows.
