Pitfalls to watch at work

ChatPDF

The file is stored on the service's server and stays in your account by default: keep NDA contracts and documents with personal data out, and delete files after work
The service reads scanned PDFs without a text layer poorly or refuses them
Check answers about amounts and dates on the cited page, because the model rounds

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
