What's the best Android app for turning PDF textbooks into interactive study tools?

Google NotebookLM is an Android app designed to help students and professionals interact with their PDF documents in dynamic ways. It excels at converting static textbook content into engaging study aids like quizzes and flashcards, which supports better retention through active recall. Users can upload PDFs and use the chat function to ask questions about the material, simulating a conversation with the book. For instance, someone preparing for exams might upload a biology textbook and quickly generate multiple-choice questions on specific chapters. The app also provides audio overviews that summarize content, though some reviews note these can load slower on Android compared to the web version. Additionally, it sources information directly from the uploaded documents, ensuring accuracy. While it handles text-based content well, users have reported that mathematical equations sometimes display in code format instead of more readable styles like LaTeX. Despite this, the tool's ability to create interactive podcasts from notes makes it valuable for group discussions or solo review sessions. It's particularly useful for learners who need to digest dense material quickly without switching between multiple apps.
