What is NotebookLM?
NotebookLM is Google's AI research notebook, launched in 2023. You upload sources (PDFs, Google Docs, slides, web pages, YouTube links) and it produces grounded summaries, FAQs, briefing docs, and its signature podcast-style Audio Overview — every answer cited back to your sources. It is free, with a NotebookLM Plus tier via Google One / Workspace.
Why students consider it: NotebookLM is the standout 2026 tool for understanding documents: its source-grounding with inline citations is best-in-class, the Audio Overviews are excellent, it's free, and it's backed by Google's models and large context window.
How Backrow is different
Both products generate flashcards and quizzes from sources. Backrow combines live lecture capture, saved notes, study workflows and specialized tools; NotebookLM emphasizes cited answers and source synthesis.
