How to Use NotebookLM to Study and Summarize PDFs⁠

Learning how to use NotebookLM is the fastest way for students, researchers, and remote workers to conquer reading overload.

Here is how to set up the tool, master your coursework, prepare for exams, and summarize long PDFs without paying a dime.
