Pitfalls 5

No upload, no answer — that is a boundary, not a bug

Don't expect outside knowledge

Split large files before upload to avoid truncation

Per-file cap

AI citations can mis-attach

Cross-check sensitive facts across sources

Lower risk

Tips

NotebookLM's core boundary is "answer only from your uploaded sources with inline citations" — it won't invent from training, which makes it a trustworthy research/study aide, provided sources are high quality.
Verification prompts (find contradictions/gaps/counterpoints) are its most underrated power: feed several docs and have it flag conflicts and blind spots — far faster than eyeballing.
Split large files into a master corpus before upload to avoid truncation; free tier is 50 sources/notebook and 10000-char custom prompts.
Learning Guide + Studio (infographic/audio) turn dry docs into a structured learning path — great for research/training.
