Pitfalls to watch at work

Mem

• Notes are stored in the service's cloud: keep passwords and employee personal data out
• An answer from your notes also pulls in outdated entries: look at the date of the note it cites
• Test the note export before moving your whole base there, so you have a way back

NotebookLM

• The model answers only from uploaded sources: if the notebook holds an old version of a law, the answer follows the old version and still sounds confident
• Keep documents with personal data and trade secrets out of notebooks in a personal account: use NotebookLM as part of Workspace for them
• Scanned PDFs without a text layer read poorly: run them through OCR first
